Route description

The hike starts from the village of Trub and follows the River Trueb and the Fankhusbach stream. In Fankhaus, you leave the rush of the stream behind and follow the existing hiking trail to the left as far as Lenn. The path now branches off to the right and climbs to Buechi and on over the ridge via Höstulle to Grüebli. From here, you head steeply uphill one last time around Schlegelgrabe up to Napf. Then follows the roughly hour-long descent to Mettlenalp.
