Backcountry Skiing Map & Planning App

Learn about the Trailforks features useful for backcountry skiing mapping, planning & navigation.

Download The App

Trailforks is dedicated to giving you the best interactive trail maps, custom designed for your selected activity.

Trailforks might have started out as a mountain biking platform, but has since expanded to an array of sports that utilize trails.
Backcountry skiing or ski touring is one of them. Enjoy all the Trailforks website and app features along with the features below, which are particularly useful for backcountry ski adventures.

avalanche risk risk

Avalanche Risk Layer

Toggle this layer on the website or app. Polygons are color based upon known avalanche danger slope angles, with red being the most dangerous areas. Many factors are involved in an avalanche (e.g. slab, a weak layer, a trigger, and a slope angle steep enough to slide). This layer only highlights angles that avalanches typically form.

Closure & Danger Zone Polygons

Polygons are contributed to the map showing areas that might be closed, or closed to motor-vehicle use. Which can help in avoiding user-conflict with snow mobiles.

High avalanche or no-go zones might also be mapped, or just a polygon showing an entire area you can ski, like an open bowl.

Winter Activity Recordings

View public tracks recorded by others, colored coded by activity in our new winter activity recordings layer. Help plan your trip route in popular zones, or seek out new terrain which is not popular.

Backcountry Ski Zones

Analyzing our public ski data we've created polygons of popular ski zones. This light-blue colored overlay is shown on the winter map (website only currently).

Mapped Trails & POIs

The database of mapped trails and routes is always growing. Find mapped trails, most commonly used for access routes for ski touring. Check recent user trail reports and other trail information.

View POIs related to ski touring, such as huts, parking spots, danger zones and more.
