18 mapped runs, 2 lifts and 7.3 km of pistes — every metre measured from open map data and viewable in 3D in the Bonvo Ski app.
Computed from mapped terrain data — no editorial opinion, no pay-to-rank. How the score works
Every run measured from elevation-aware map geometry: true length, vertical drop, average gradient and a 0–10 slope score that rewards long, sustained descents.
