The Sentier des Bouquetins is an educational trail that explores the fauna, flora, history and geology of the Grande Dixence region, providing an overview of a pioneering hydroelectric complex. The trail was inaugurated in 2012 and features seven stops – including the Prafleuri hut, ideal for a drink.
Details of the walk are in an 86-page brochure available in English, German and French, which can be downloaded free of charge. Hard copies are available for purchase at the dam’s information pavilion (free admission).
The trail starts near the dam’s crown through a series of tunnels along the lake. The ascent through flowery meadows to the Col des Roux at 2803 m altitude offers good chances to see ibexes – the wild cousins of domestic goats, immediately recognizable by their beautiful arched horns. Beyond the pass, the glacial moraines of the Combe de Prafleuri provided the raw material for the dam in the form of rocks crushed into gravel.
The trail can be taken in two directions:
– either along the Lac des Dix (recommended direction, walking time to the Prafleuri hut: 02:30),
– or through the Prafleuri combe (walking time to the Prafleuri hut: 01:30).
Take good shoes, a waterproof jacket, water and sun protection (cream, glasses, hat..). Path, stony and narrow in places, intended for hikers with an average physical condition and children from 8 years.
