Bivouac & Wild Camping · Randa → Grächen, ValaisBivouac the Europaweg past the Charles Kuonen Suspension BridgeEXPERTRisk: HIGHFreeHike the exposed high route between Zermatt and Grächen, crossing the 494m Charles Kuonen Suspension Bridge — one of the longest pedestrian suspension bridges in the world, hung 85m above the Grabengufer ravine.

Exposed scrambling sections either side of the bridge in poor weather turn this from a hike into a real objective.View details
