Interest
Places where the night is part of the trip: dark-sky parks in the American West, an island with no street lights, and northern lights seasons from Lofoten to Churchill.

Dark-sky places with no published season are not in this table. You will find them in the cards above.
Roughly late August to April, depending on how far north. Lofoten's season runs from late August to mid-April, Rovaniemi's from late August to early April and Greenland's from late August to April; Iceland is dark enough from September to April; Svalbard's Northern Lights Winter runs from 1 October to 28 February; Churchill's best months are February and March; and the Northwest Territories have two seasons, mid-August to late September and mid-November to early April. These are the tourism boards' own seasons, not a forecast.
Sark, in the Channel Islands. It was recognised by the International Dark-Sky Association in 2011 and became the first island community called a Dark Sky Island, largely because it has no street lights.
Togo Chasm, on Niue. Niue is the first whole country to receive Dark Sky Sanctuary and Community accreditation from DarkSky International, and trained Niuean community members lead its guided astro-tours.
From mid-November to late January, when the sun stays more than 6 degrees below the horizon and the northern lights may show in the middle of the day. Svalbard's Northern Lights Winter season runs from 1 October to 28 February.
For a seabird. Kaikōura's dark-sky push began in 2020 to help protect the endangered Hutton's shearwater, which is affected by artificial light at night, and the coast became an International Dark Sky Sanctuary on 12 September 2024.
None of the places on this page sits in the path of totality. For eye safety during any solar eclipse, NASA keeps a safety page (https://science.nasa.gov/eclipses/safety/).
A place joins this page when its park, reserve, community trust or tourism board publishes something about its night sky: a dark-sky designation, a northern lights season, a star party or a stargazing programme. Each place carries at least three of these, each linked to its source. The calendars on the cards show the seasons as each park, reserve or tourism board publishes them. Where a board gives a season for a whole country or territory, as Visit Iceland and Northwest Territories Tourism do, the card says so.
No rankings and no forecasts: the sky keeps its own schedule. Park rules, closures and seasons change, so each card links the page with the current word.
