Built for a clearer ski day
Mountainmapper is developed by Otto Zhang in France. The app and this website support English, French and Simplified Chinese. Core maps and standard route planning work without an account.
A planning aid, with clear limits
Map data can be incomplete or out of date. The app does not provide live piste closures or guarantee route safety. Always follow resort signs, closures and staff instructions. Product screenshots on this site show the app; they are not evidence that every pictured connection is currently open.
Help improve the experience
For a map issue, app problem or suggestion, contact support with a short description, your device and app version. Do not send passwords or precise location data. The privacy policy explains how personal information is handled.
