Which mountains and trails can I find?

Any named peak or volcano on OpenStreetMap, worldwide, and any named trail. Pick a peak and the builder lists the hiking routes and named paths round it, the ones that reach the summit first. Tick the trail you climbed, tick two to join them, or tick none for the mountain alone. The famous climbs (Whitney, Half Dome, Longs Peak, Kilimanjaro, the Matterhorn and more) are ready to tap.
