FatMap, the 3D mountain map many skiers relied on, shut down on 1 October 2024, after Strava bought it. Ski Info is a free alternative for ski resorts: 3D terrain with every run and lift of 1,409 resorts in 45 countries, plus the real slope of every run, stretch by stretch.
Tap a resort to open its 3D map. Every other one is in the search on the home page.
Ski Info is about ski resorts: no ski touring or backcountry routes, and no iPhone app (the website can be added to the home screen and works like an app). Each resort can be downloaded to use offline (the 2D map with its satellite imagery; 3D needs a connection).
Yes. Strava bought FatMap in January 2023 and shut it down on 1 October 2024; some of its features moved to Strava.
Ski Info (skiinfoapp.com) is free with no sign-up: a 3D terrain map with the runs and lifts of 1,409 ski resorts, and the slope of every run.
On each resort's page on Ski Info: every run has its gradient profile stretch by stretch, in % and degrees, and its steepest 50 m stretch.
