Slide, jump and wade through the Sorba–Nonay gorge in Val Sesia on a guided canyoning descent. About two hours of in-gorge action with wetsuit, helmet and harness provided and hot showers back at base.
Slide, jump and wade through the Sorba–Nonay gorge in Val Sesia on a guided canyoning descent. About two hours of in-gorge action with wetsuit, helmet and harness provided and hot showers back at base.
The gorge narrows and the river speaks in clicks and white water as you clip into a harness and step toward rock polished smooth by centuries of flow. In the Sorba–Nonay section of Val Sesia you move between walls of greying gneiss, sliding natural chutes, jumping into plunge pools and edging along ledges while the guide reads the current and the canyon answers with cold, fast water.

The gorge narrows and the river speaks in clicks and white water as you clip into a harness and step toward rock polished smooth by centuries of flow. In the Sorba–Nonay section of Val Sesia you move between walls of greying gneiss, sliding natural chutes, jumping into plunge pools and edging along ledges while the guide reads the current and the canyon answers with cold, fast water.
This valley sits on the southern flank of the Monte Rosa massif; glaciers carved the steep-sided gorges and the same hard metamorphic rocks that built nearby alpine villages frame the descent. Val Sesia has a mixed culture—traditional mountain farming and the Walser communities higher in the valley—so the canyon experience sits alongside centuries of human use of water, stone, and seasonal pasture. Local guides pair modern safety with regional knowledge, pointing out rock features and historic trails visible above the gorge.
Practical note: the active part of the trip is about two hours in-canyon; fittings, briefing, and transfers bring total time closer to three. You’ll be given a wetsuit, helmet, and harness; expect cold water, short swims, and occasional jumps into deep pools. Bring a swimsuit, sturdy river shoes, and a warm synthetic underlayer for after. Minimum age is 18; the company provides a minibus return and hot showers at the center. Plan to arrive hydrated and ready to follow guide instructions—this is playful, controlled exposure to moving water rather than a free-for-all.
