Trailmap is a free service for mountain bikers, trail runners and other outdoor enthusiasts to discover new trails and plan new routes.
Various maps: You get a good picture of the terrain and especially the trails that are suitable for mountain biking and trail running
Possibility to view tracks on the map: You can download both GPX tracks and tracks from Strava activities
Function for creating routes: Automatic routing along paths allows you to compare different routes quickly. You can either save the routes you draw as GPX files or send them to Garmin devices for navigation on the trails.
Trailmap utilises many types of open map data and has an active user base who map new routes and save them to OpenStreetMap.
In addition to the website, Trailmap is also available as a mobile application Trailmap Suomi for Android devices and Apple iOS.
