The Field Guide

Places worth knowing

A growing archive. Each entry covers one place — where it is, what happened there, and the single detail that makes it stick. New entries are added regularly.

Regions

Regions cover the whole Field Guide — every place has exactly one. Each carries its own map.

Collections

Collections cross and subdivide the regions, because some places make more sense together: how a season works, how a route runs, what an area is actually like. A place can belong to several.

    The Drake Passage

    Southern Ocean · Open ocean crossing

    South Georgia

    South Atlantic · Subantarctic tundra & coast

  • Entry № 011

    The Aletsch Glacier

    Valais, Switzerland · High-alpine glacial ice

  • Entry № 012

    Sequoia National Park

    California, USA · Mixed-conifer montane forest

    The largest tree on Earth by volume, and a species whose cones can stay sealed for twenty years and open only in fire.

  • Entry № 013

    Cueva de las Manos

    Santa Cruz, Argentina · Patagonian steppe

    Perito Moreno Glacier

    Santa Cruz, Argentina · Subpolar glacial ice

    Acadia National Park

    Maine, USA · Coastal spruce-fir & hardwood
    Part of The US National Parks

    Torres del Paine

    Magallanes, Chile · Subpolar forest & steppe

    Isle Royale

    Michigan, USA · Boreal island wilderness

  • Entry № 021

    Katmai & Brooks Falls

    Alaska, USA · Subarctic river & tundra

  • Entry № 022

    Fernandina

    Galápagos, Ecuador · Young volcanic island

    The youngest Galápagos island: no introduced species ever, an active volcano, the biggest marine iguanas — and a tortoise that hid for 113 years.

  • Entry № 023

    Kaikōura

    New Zealand · Submarine canyon coast

    A deep-sea canyon starts almost at the beach, so sperm whales feed year-round within sight of a town whose name means 'eat crayfish'.

  • Entry № 024

    Lord Howe Island

    Australia · Subtropical island

    An island capped at 400 guests at a time, with the world's southernmost coral reef and the tallest sea stack on Earth next door.

  • Entry № 025

    The Bay of Fundy

    Part of Canada

    The highest tides on Earth: walk the ocean floor at low water, paddle over your footprints six hours later.

  • Entry № 026

    Nahanni

    Northwest Territories, Canada · Subarctic wilderness
    Part of Canada

    Náįlįcho, a waterfall twice Niagara's height, and four great canyons in a roadless reserve — among the first UNESCO sites ever listed.

  • Entry № 027

    The Osa Peninsula

    Costa Rica · Pacific lowland rainforest

    The most biologically intense place on Earth, by National Geographic's famous description — tapirs at the ranger station, macaws over the beach.

  • Entry № 028

    Coober Pedy

    South Australia · Stony desert

    The opal capital of the world solved the desert sun by moving underground — homes, churches, hotels, and a golf course with no grass at all.

  • Entry № 029

    Pico

    Azores, Portugal · Volcanic island

    Portugal's highest mountain in the mid-Atlantic, with UNESCO vineyards walled in black lava and whales off the old whaling coast.

  • Entry № 030

    Mykines

    Faroe Islands · North Atlantic basalt

    The westernmost Faroe: vast puffin colonies, the islands' only gannets, and a lighthouse across a sea gorge.

  • Entry № 031

    Sedona

    Arizona, USA · Red rock country

    Sandstone stained by rust, a chapel grown from a cliff, and a town named for the postmaster's wife.

  • Entry № 032

    The Iberá Wetlands

    Corrientes, Argentina · Freshwater marsh

    Shining waters where jaguars walk free again after seventy years — rewilding's great showcase, patrolled by unbothered capybaras.

  • Entry № 033

    Sossusvlei & Deadvlei

    Namibia · Hyper-arid sand desert

    A forest that died six centuries ago and never fell — black trees on white clay beneath the rusted-red dunes of Earth's oldest desert.

  • Entry № 034

    Hang Sơn Đoòng

    Central Vietnam · Tropical karst cave

    The world's largest cave keeps its own clouds and grows its own jungle — found by a farmer sheltering from a storm, then lost for eighteen years.

  • Entry № 035

    Living Root Bridges

    Meghalaya, India · Monsoon forest

    In the wettest inhabited place on Earth, the Khasi grow bridges from living fig roots — architecture that heals itself and strengthens with age.

  • Entry № 036

    Song-Köl

    Kyrgyzstan · High-alpine steppe

    A lake two miles up with no town and no trees — only a season: yurts and herds arrive each June, and by October it all belongs to the wind again.

  • Entry № 037

    Zhangjiajie & Wulingyuan

    Hunan, China · Sandstone peak forest

    Three thousand stone towers wearing trees for hats — when the mist rises past their feet, whole mountains cast off and float.

  • Entry № 038

    Þingvellir

    Southwest Iceland · Subarctic rift valley

    A parliament founded in 930 met for eight centuries on a valley floor that was steadily sinking and splitting beneath the argument.

  • Entry № 039

    Dominica

    Eastern Caribbean · Tropical montane rainforest

    Too steep for sugar, so the forest stayed — and offshore, sperm whale families live year-round instead of migrating.

  • Entry № 040

    Svalbard

    Arctic Norway · High Arctic tundra & glacier

    Four months without a sunrise, forty-six nationalities free to move in, and the world's spare seeds sealed inside a mountain.

  • Entry № 041

    Paro Taktsang

    Paro District, Bhutan · Himalayan cliff forest

    A monastery glued to a rock wall nine hundred metres above the valley, in a country that writes its forests into its constitution.

  • Entry № 042

    Cappadocia & Derinkuyu

    Nevşehir Province, Türkiye · Volcanic tuff plateau

    Rock soft enough to carve and firm enough to hold a ceiling — so when armies came, whole communities went eighteen storeys down.

  • Entry № 043

    Lofoten

    Nordland, Norway · Subarctic island coast

    Harbours that refuse to freeze at 68° north, and a thousand-year export trade built on one fish keeping an appointment.

  • Entry № 044

    Plitvice Lakes

    Lika-Senj & Karlovac counties, Croatia · Dinaric karst

    Sixteen lakes held back by dams that moss, algae and bacteria are still building, roughly a centimetre or two a year.

  • Entry № 045

    Meteora

    Thessaly, Greece · Conglomerate pinnacles

    A river delta turned to stone and stood on end, with fourteenth-century monasteries on the flat bits.

  • Entry № 046

    Raja Ampat

    Southwest Papua, Indonesia · Coral Triangle reef & karst

    The highest reef biodiversity ever recorded, on islands that also happen to be made of battery metal.

  • Entry № 047

    The Flaming Cliffs

    Ömnögovi Province, Mongolia · Gobi desert-steppe

    In 1923 a team here found the first dinosaur eggs anyone recognised as such, and science blamed the wrong animal for stealing them for seventy years.

  • Entry № 048

    Taroko Gorge

    Hualien County, Taiwan · Marble gorge

    A river cuts through solid marble while the island keeps rising to meet it — and since 2024, the gorge has been carefully putting itself back together.

  • Entry № 049

    The cenotes of the Yucatán

    Yucatán, Mexico · Karst sinkholes

    An asteroid cracked the bedrock in a ring 66 million years ago; the sinkholes tracing that ring today are far younger than the shortcut version says.

  • Entry № 050

    The Okavango Delta

    North-West District, Botswana · Endorheic inland delta

    A flood sourced a thousand kilometres away arrives exactly when Botswana's dry season leaves nothing else wet.

  • Entry № 051

    Cirque de Mafate

    Réunion, Indian Ocean · Tropical montane cirque

    Around eight hundred people live inside a collapsed volcano with no road — everything they own arrived on a back or under a helicopter.

  • Entry № 052

    The Makgadikgadi Pans

    North-East District, Botswana · Salt pan & grassland

    A salt flat on the floor of a lake that outlived its rivers, and the zebra still cross it twice a year.

  • Entry № 053

    Etosha

    Kunene and Oshana, Namibia · Semi-arid savannah & salt pan

    A pan so barren that water becomes the scarce thing, so the animals queue for it rather than scatter across the park.

  • Entry № 054

    Chã das Caldeiras

    Fogo, Cabo Verde · Active volcanic caldera

    A village farming inside an active crater, rebuilt on the lava that buried it in 2014 though the state said not to.

  • Entry № 055

    Vallée de Mai

    Praslin, Seychelles · Endemic palm forest

    A palm forest holding the largest seed on Earth, which had a mythology for centuries before anyone found the tree.

  • Entry № 056

    SG̱ang Gwaay

    Haida Gwaii, British Columbia · Coastal temperate rainforest

    Cedar mortuary poles left to lean, weather and fall — because the Haida Nation decided they should, and UNESCO's listing accepts it.

  • Entry № 057

    Mammoth Cave

    Kentucky · Karst limestone cave system

    The longest cave known, and still growing. The 1972 connection that made it so was already on an enslaved guide’s map, drawn from memory in 1842.

  • Entry № 058

    The Hopewell Ceremonial Earthworks

    Ohio · Monumental earthwork complexes

    Earthworks aligned to a lunar cycle of 18.6 years — a pattern nobody could establish alone, since a person sees only about three of them in a lifetime.

  • Entry № 059

    Wood Buffalo National Park

    Alberta / Northwest Territories · Boreal plain & delta

    Bigger than Switzerland, with the only wild nesting ground of the whooping crane and a beaver dam found from orbit — and 4,000 visitors a year.

  • Entry № 060

    Great Sand Dunes

    Colorado · Dunefield & alpine tundra

    The tallest dunes in North America exist because two creeks carry the escaping sand back. In late spring one of them runs in waves, every twenty seconds.

  • Entry № 061

    Hamelin Pool

    Shark Bay, Western Australia · Hypersaline marine embayment

    Microbes have built rock here since before anything could eat them. They survive because the water is twice as salty as the sea.

  • Entry № 062

    Purnululu

    East Kimberley, Western Australia · Sandstone range & savanna

    Beehive domes striped orange and black, standing only because a living skin of bacteria binds sandstone that would otherwise fall apart.

  • Entry № 063

    Tongariro

    Central North Island, New Zealand · Active volcanic plateau

    Three sacred volcanoes given to the Crown in 1887 to stop them being sold — and the first cultural landscape ever inscribed on the World Heritage List.

  • Entry № 064

    Rakiura

    Southland, New Zealand · Podocarp forest & coast

    No stoats, so the kiwi feed in daylight — which is how kiwi used to be everywhere. Also the southernmost Dark Sky Sanctuary on Earth.

  • Entry № 065

    Kati Thanda–Lake Eyre

    Far North, South Australia · Endorheic salt lake

    A salt pan most of the time. When floodwater finally arrives from Queensland, pelicans appear in their tens of thousands, and nobody knows how they know.

  • Entry № 066

    The Florida Keys

    Monroe County, Florida · Limestone island chain

    A hundred and thirteen miles of highway across open water, built on the piers of a railroad a hurricane destroyed in 1935. The old bridges still run alongside.

  • Entry № 067

    St John

    US Virgin Islands · Dry tropical forest over plantation

    Sixty per cent of the island is national park, and the forest everyone calls pristine is second growth over terraced sugar plantations.

  • Entry № 068

    Upper Svaneti

    Samegrelo-Zemo Svaneti, Georgia · High Caucasus valleys

    Stone towers built one per family, entered by a ladder you pulled up behind you — defences against invaders, and against the family next door.

  • Entry № 069

    The haenyeo of Jeju

    Jeju Province, South Korea · Volcanic island coast

    Women who dive to twenty metres on one breath, by rule and without tanks. Over 4,500 of them in 2013; about 2,600 by the end of 2024.

  • Entry № 070

    Scoresby Sund

    Sermersooq, East Greenland · Arctic fjord system

    The largest fjord system on Earth, with one town of about 350 people at its mouth — placed there in 1925 to establish a claim.

  • Entry № 071

    The Saloum Delta

    Fatick Region, Senegal · Mangrove delta and shell mounds

    Mangrove islands that are partly made of shells: 218 mounds of discarded cockles and oysters, piled up over two thousand years. Some of them are cemeteries.

  • Entry № 072

    Príncipe

    São Tomé and Príncipe · Equatorial rainforest island

    A tiny equatorial island where a 1919 eclipse photographed through cloud helped make Einstein famous — on a cocoa estate with a much harder history.

  • Entry № 073

    Gunung Mulu

    Sarawak, Malaysian Borneo · Caves and rainforest

    No road in, some of the largest caves on Earth, and millions of bats pouring out of one at dusk. Several of its famous records are out of date.

  • Entry № 074

    Nan Madol

    Pohnpei, Micronesia · Stone city on a reef

    Around a hundred artificial islets walled with basalt columns stacked like logs, on a reef off Pohnpei. The coral inside its first tomb dates it to about 1180.

  • Entry № 075

    Deception Island

    South Shetland Islands · Volcanic caldera harbour

    The best harbour in the South Shetlands is the flooded crater of an active volcano. Ships sail in through a gap in the cliffs, and the beach steams.

  • Entry № 076

    Victoria Falls

    Zambia and Zimbabwe · Waterfall that walks upriver

    Classed as the largest sheet of falling water on Earth, and a waterfall that keeps walking upriver: the zigzag canyon below it is where it used to be.

  • Entry № 077

    Machu Picchu

    Cusco Region, Peru · Inca estate above a canyon

    The best-known ruin in the Americas, and possibly not called Machu Picchu at all: two scholars argue that name came from an American's 1911 publications.

  • Entry № 078

    Salar de Uyuni

    Potosí, Bolivia · Salt flat used to calibrate satellites

    The largest salt flat on Earth, level enough that space agencies test satellites against it, and a mirror when it rains.

  • Entry № 079

    The Nazca Lines

    Ica Region, Peru · Desert geoglyphs

    Hundreds of huge lines and animal figures scratched into a Peruvian desert, still being found: in 2024 AI helped confirm 303 new ones.

  • Entry № 080

    The Great Blue Hole

    Lighthouse Reef, Belize · Flooded cave in a reef

    A perfectly round hole in a Caribbean reef, and a flooded cave: the stalactites in its walls prove it was dry when the ice ages had drawn the sea down.

  • Entry № 081

    The Giant’s Causeway

    Northern Ireland, UK · Basalt columns and an argument about rock

    About 40,000 basalt columns stepping into the sea. They helped settle whether basalt comes from water or from volcanoes, and a tray of drying cornflour grows the same pattern.

  • Entry № 082

    Venice

    Veneto, Italy · A lagoon kept a lagoon on purpose

    The lagoon that protects Venice was kept a lagoon on purpose: for nearly two centuries the Republic dug new beds to carry rivers and their silt around it. Now the barrier faces the other way.

  • Entry № 083

    Neuschwanstein

    Bavaria, Germany · A retreat opened seven weeks after its king died

    Built as one shy king's retreat from public life, closed to outsiders while he lived, and opened to the public seven weeks after he died. The throne it was built around was never made.

  • Entry № 084

    The Alhambra

    Granada, Spain · A palace whose walls speak in verse

    A palace whose rooms speak in the first person: the Alhambra's court poets wrote verses for the walls, and the Fountain of the Lions describes its own water. Its famous tile-symmetry claim is less settled.

  • Entry № 085

    Malta

    Malta · Cart ruts that run into the sea

    Paired grooves cut into the bare limestone, crossing like a rail yard at 'Clapham Junction' and running into the sea at Birżebbuġa. Nobody agrees who made them or when.

  • Entry № 086

    The Great Barrier Reef

    Queensland, Australia · A reef that has moved five times

    The world's largest reef system has died five times in 30,000 years, stranded as the sea fell and drowned as it rose, and survived each time by moving. The reef you swim over is less than 10,000 years old.

  • Entry № 087

    Milford Sound / Piopiotahi

    Fiordland, New Zealand · Where the rain lifts the deep sea

    So much rain falls here that fresh water floats on the sea like a lid, and deep-sea black coral grows within a diver's reach. The boats pass right over it.

  • Entry № 088

    The Twelve Apostles

    Victoria, Australia · Never twelve, and five more under the sea

    Named for tourists, never twelve, and now seven: the stacks were carved in the last few thousand years, and the only extra Apostles anyone has found stand drowned offshore.

  • Entry № 089

    Aoraki / Mount Cook

    Canterbury, New Zealand · A mountain that lost thirty metres

    Measured at 3,764 metres for a century, New Zealand's highest mountain lost ten metres in a night in 1991 and thirty more since. To Ngai Tahu it is an ancestor, not a summit.

  • Entry № 090

    The Blue Mountains

    New South Wales, Australia · A plateau, and a tree kept secret

    Not mountains but a sandstone plateau cut into gorges, blue because of its eucalypts and World Heritage-listed for them. One canyon hid a tree known only from fossils until 1994.

  • Entry № 091

    The Grand Canyon

    Arizona, United States · A canyon still dated three ways

    Nearly two billion years of rock, and a hole cut through it that geologists still date three ways: 70 million years for part of it, 5 to 6 million for the whole, or a lake that spilled.

  • Entry № 092

    Yellowstone

    Wyoming, Montana and Idaho, United States · Hot springs coloured by living microbes

    The colours around Yellowstone's hot springs are living microbes. From one small pool off the boardwalks came the bacterium whose enzyme made copying DNA practical.

  • Entry № 093

    Niagara Falls

    Ontario, Canada and New York, United States · A waterfall on a treaty timetable

    A treaty sets how much water goes over Niagara Falls: twice as much by day in the tourist season as at night. The rest goes through tunnels to power stations, and in 1969 the American Falls was turned off.

  • Entry № 094

    Banff

    Alberta, Canada · A park born of a hot-spring quarrel

    Canada's national parks began with a quarrel over a hot spring in 1885. The spring is now closed to bathers, because it is the main home of a snail found nowhere else.

  • Entry № 095

    Churchill

    Manitoba, Canada · Where polar bears wait for the ice

    Polar bears gather at Churchill each autumn to wait for Hudson Bay to freeze. The ones that come into town can be held by the province until the ice forms, then let go onto it.

  • Entry № 096

    Angkor Wat

    Siem Reap, Cambodia · One temple in a hidden city grid

    The famous building is one temple. Lidar flown in 2012 showed the forest around it hides a planned city of embankments, ponds and roads, and the temple was built into the grid.

  • Entry № 097

    Mount Fuji

    Shizuoka and Yamanashi, Japan · A summit that belongs to a shrine

    The summit of Japan's national symbol is shrine land: the state took it after the Meiji Restoration, the Supreme Court ruled for the shrine in 1974, and it was handed back in 2004. The prefectural border across the top was never drawn.

  • Entry № 098

    The South Pole

    Antarctica · A pole marked again every New Year

    The pole stays put; the ice on top of it moves about ten metres a year. So every New Year's Day the station's people mark the pole again, with a marker made by hand over the winter.

  • Entry № 099

    The Avenue of the Baobabs

    Menabe, Madagascar · The last trees of a cleared forest

    The giant baobabs along the road north of Morondava did not grow as an avenue. They are what remains of a forest cleared for farming, and the land around them is poor ground for young trees.

  • Entry № 100

    Ilulissat Icefjord

    West Greenland · Icebergs queuing at the fjord’s mouth

    The glacier behind Ilulissat's icebergs slowed and thickened from 2016 as the sea cooled, then sped up again from 2018 before the warm water came back. Its biggest icebergs still queue on a ridge at the fjord's mouth.

  • Entry № 101

    Vatican City

    Vatican City, enclaved in Rome, Italy · A border drawn in the paving

    The smallest country in the world meets Italy along a white stone line across St Peter's Square. By the 1929 treaty the square is the Vatican's, and on an ordinary day Italian police keep order in it.

  • Entry № 102

    Santiago de Compostela

    Galicia, Spain · A pilgrimage waymarked in yellow paint

    A pilgrimage made since the ninth century, waymarked since 1984 by a parish priest's yellow arrows and proved with a book of stamps, ending at a granite cathedral in Galicia.

  • Entry № 103

    Ephesus

    İzmir Province, Türkiye · A harbour city its river left inland

    One of the great ports of the Roman world, left inland by its own river. Ephesus moved more than once to follow a coastline that silt kept pushing west.

  • Entry № 104

    Ronda

    Málaga, Andalusia, Spain · A bridge built from the gorge below

    A town on both lips of a gorge, joined by a bridge 98 metres high that was built of stone cut from the bottom of the gorge itself. It is called the New Bridge, and it was finished in 1793.

  • Entry № 105

    Patmos

    Dodecanese, Greece · An island an emperor gave a monk

    In 1088 a Byzantine emperor granted a small Aegean island to a monk. He built a monastery with battlements above the harbour, and a white town grew up around its walls.

  • Entry № 106

    Iguazú Falls

    Misiones (Argentina) and Paraná (Brazil) · Falls that nobody counts the same way

    Argentina's park counts 275 falls; other accounts give 150 to 300, because the number depends on the river. The same river wrecked the walkway to the Devil's Throat in 2023, and it was taken apart again in 2026 before an expected flood.

  • Entry № 107

    Kruger National Park

    Limpopo and Mpumalanga, South Africa · A hundred years old, founder disputed

    South Africa's first national park turned 100 in 2026. It is named for President Paul Kruger, and historians have argued since 1994 about how much he had to do with it.

  • Entry № 108

    Ha Long Bay

    Quang Ninh province, Vietnam · Tower karst the sea moved into

    A limestone tower landscape that the sea has flooded: UNESCO calls it the most extensive marine-invaded tower karst on Earth. Every island carries a notch the tide has dissolved at its foot.

  • Entry № 109

    Bora Bora

    Leeward Islands, Society Islands, French Polynesia · Arrival by a wartime runway

    Visitors still land on an airstrip US forces built on a reef islet in 1943 for a wartime fuel base, then cross the lagoon by boat. For years it was French Polynesia's only international airport.

  • Entry № 110

    Ross Ice Shelf

    Ross Sea, Antarctica · A floating cliff at the end of the sea
