Les Diablerets, 1865 Ormont-Dessus, Switzerland
Via Ferrata Les CascadesAt 450m long and graded D+ (difficult) this is probably quite a challenging Via Ferrata - there are overhanging sections, it's physically demanding, some very exposed sections, and it's hot - even in the shade! If that's not for you, there is a beginner route off to the left of the starting point.
Accessible by foot from Les Diablerets, follow the signs for the Col du Pillion and the Glacier 3000 - it's also possible to park at the cable car station.
Les Cascades is well signposted - the short walk to the starting point travels though lush Alpine fields, with the odd Milka cow enjoying the grazing.
The via ferrata route follows the mountain ledges - there are a range of holds, steps, and wire crossing - the route culminates at a zip-wire crossing through a lovely cooling waterfall!
The season for via ferrata in Switzerland is usually from June to October.
