Hiking and the Alps
Trampelpfade am Uetliberg
The Uetliberg (the 870m tall hill rising above Zürich) is full of fascinating and sometimes surprisingly challenging unofficial hiking trails ("Trampelpfade"). Documenting these has been the masterwork of Martin "Uto869" on Hikr. I have digitized all the routes and created an interactive map.
My hikes in Switzerland
All my hikes (and via ferrata, fell running, mountaineering, ski tours and snow shoe tours) in Switzerland since 2013 on a single interactive map.
