Watched breakfast being caught from a platform built specifically for watching breakfast. The fish are brave and the bears are patient and I am neither, which is what the railing is for. I picked a favourite bear within the hour. I have since revised my choice four times and regret nothing.
The short answer
Katmai National Park and Preserve covers a vast, roadless stretch of the Alaska Peninsula, reachable only by floatplane or boat. It protects an estimated 2,200 brown bears — on a peninsula where bears are commonly said to outnumber people — and its centrepiece is Brooks Falls, where the bears gather each July to catch sockeye salmon leaping the falls on their way upstream. Elevated platforms let visitors watch from a few dozen metres. The park was first protected in 1918 for a different reason entirely: the aftermath of one of the largest volcanic eruptions ever recorded.
Why it's worth knowing
Wildlife watching is usually a search. Katmai in July is the opposite: the animals commute to a known address at a known time, because the salmon do. When the sockeye run peaks, dozens of bears may work the short stretch of the Brooks River, and the falls concentrate the action into a single frame — fish in the air, bear at the lip, jaws open.
What the platforms actually show is bear society. The best fishing spots are held by rank: dominant males at the lip and the jacuzzi below it, mothers with cubs at respectful distances, adolescents relegated to the leftovers downstream. Every bear knows exactly where it stands, literally. Regulars are known by number, and some have held the same fishing spot for a decade or more.
The field notes
Born of an eruption
Katmai's original monument, proclaimed in 1918, protected not bears but a landscape still smoking: the aftermath of the 1912 Novarupta eruption, among the most powerful of the twentieth century, which buried a nearby valley under volcanic ash so hot it steamed from thousands of vents for years. The explorers who found it named it the Valley of Ten Thousand Smokes.
The smokes have gone out, but the valley remains an extraordinary place — a river-cut plain of pale ash walled by volcanoes, reachable by a daily bus-and-hike excursion from Brooks Camp. It is the reason the park exists, and most visitors never see it, which is an argument for being the visitor who does.
How the falls work
Sockeye salmon return from the ocean each summer and push up the Brooks River toward their spawning lakes. The falls are a metre-and-a-half problem the fish solve by leaping — and every leap is a moment airborne in front of animals that have learned exactly where the fish emerge.
The run peaks in July, when bear numbers at the falls are highest. By August the fish disperse and so do the bears; in September they return downstream for the season's second act, feeding on spawned-out salmon. Four elevated platforms — at the falls, the riffles below, and the river mouth — keep watchers above the traffic, and every arriving visitor gets a ranger's bear-safety briefing before going anywhere.
The fattest bear wins
Katmai's rangers turned autumn weight gain into a public event: Fat Bear Week, begun in 2014 as a single Fat Bear Tuesday and now an annual online tournament run with the operators of the Brooks Falls webcams. The public compares before-and-after photographs of known bears and votes a champion — a bracket contest that drew over a million and a half votes in 2025.
The joke is the point, and so is the biology underneath it: the fat is survival, laid down against a winter of dormancy, and the contest has taught an enormous audience how brown bears actually work. Champions become minor celebrities; several have won more than once.
- Watch the falls until a fish makes it over. Cheer inwardly; commotion is frowned upon.
- Pick a favourite bear. Revise hourly.
- Attend the ranger talk and follow the rules to the letter of the letter.
- Eat my own lunch indoors, like a law-abiding snack.
- Cast my vote in the autumn, from wherever I am by then.
The wait at the lip. A mature brown bear stands motionless at the top of Brooks Falls, facing upstream, jaws open, letting the river deliver. It is the laziest-looking feat of expertise in the animal kingdom — the position, the patience and the timing all learned over years — and when it works, the sound of the catch carries clearly to the platform.
Tally, in the marginProfessional patience, jaws-open method — I am taking notes for every queue I shall ever stand in again.
Getting there
There are no roads. Most visitors fly to King Salmon by scheduled service from Anchorage, then take a floatplane to Brooks Camp, landing on the lake by the ranger station; day trips also operate by floatplane from Anchorage, Homer and Kodiak. Brooks Camp services run from the start of June to mid-September, with a lodge, a campground and ranger programmes, and every arrival begins with the mandatory bear-safety orientation.
July is the peak of the salmon run and of demand — lodge rooms and campsites book out far in advance, and platform time at the falls can be managed by rangers in busy spells. September offers the second feeding season with fewer people. All food is eaten and stored only in designated areas, and the rules exist because the neighbourhood's residents weigh several hundred kilograms.
Common questions
Where can you watch bears catch salmon in Alaska?
Brooks Falls in Katmai National Park is the classic site: brown bears gather at the falls each July to catch sockeye salmon leaping upstream, and elevated viewing platforms let visitors watch from close range. A second feeding season follows in September as bears return for spawned-out fish.
How many bears are in Katmai National Park?
The National Park Service estimates around 2,200 brown bears in Katmai, and bears are commonly said to outnumber people on the Alaska Peninsula. During the July salmon run, dozens may fish the short stretch of the Brooks River at once.
What is Fat Bear Week?
Fat Bear Week is an annual online tournament run by Katmai National Park with the operators of the Brooks Falls webcams, in which the public votes on which bear has fattened most successfully before winter. It began in 2014 as a one-day event created by a park ranger and drew more than 1.5 million votes in 2025.
What is the Valley of Ten Thousand Smokes?
The Valley of Ten Thousand Smokes is an ash-filled valley in Katmai created by the 1912 Novarupta eruption, among the most powerful of the twentieth century. For years afterwards the hot ash steamed from thousands of vents, which gave the valley its name. Protecting it was the original purpose of the park, proclaimed as a national monument in 1918.
How do you get to Brooks Falls?
There is no road access to Katmai. Most visitors fly from Anchorage to King Salmon, then take a floatplane to Brooks Camp; day trips also run by floatplane from Anchorage, Homer and Kodiak. From the camp, a trail and elevated platforms lead to the falls. Services operate from June to mid-September.
Is it safe to watch the bears at Brooks Falls?
Brooks Camp manages proximity carefully: every arriving visitor receives a mandatory ranger briefing, viewing is from elevated platforms, food is confined to designated areas, and rangers manage access in busy periods. The system has allowed decades of close viewing, and the rules are the reason it works.
