Unroll an alpine chart and find one continuous route through every trail segment. Choose a legal trailhead, follow the cairns, and leave a bright orange ribbon across the map. Each edge may be walked only once, so a tempting branch can leave the rest of the mountain out of reach.
Explore 18 handcrafted maps across the Foothills, Highlands, and Summits. The compass scene helps you find the right starting cairn: maps with odd junctions begin at one of those endpoints, while loops can start anywhere. The trail atlas keeps a permanent stamp for each completed map.
Lift your finger to pause a route and resume from its orange pennant. Undo one segment or retry the current chart when a branch strands unwalked trails. Your active route and earned stamps are saved locally. Summit Trail plays offline, with no advertisements or purchases.
Trace every hiking trail once and stamp your alpine atlas.
