Walk the Plank!
In Crans we hiked Le bisse du Rho. It was a bit of a hairy climb down to it via a wire ladder and we almost thought of turning back but we knew my parents had gone ahead of us to meet us there!
Then just at the start of the Bisse proper the heavens opened for 20mins and then the sun came out and steam dried our clothes! Towards the end yes we did have to walk on those planks - just don't look down is all I can say! waterproofs!
