The pass itself doesn't stand out for anything special. Its last 2 km on the northern slope are beautiful, as it passes through the village of Aune. This pass is worth visiting for two reasons: first, because legend has it that Mr. Campagnolo invented the gear shift on a bicycle to reach its summit; second, because of the tradition of ringing the bell at the church at the foot of the road before reaching the village of Aune.
