SwissChallenge Team


The SwissChallenge team will ensure you have a safe and unforgettable adventure in Ticino. Our highly trained and experienced local guides can show you why Ticino is the best place in the world for canyoning. We live, work, and play in the Riviera Valley, the heart of canyoning in Ticino. When we have time off, we do private canyoning trips to explore and equip new canyons, ensuring that SwissChallenge is always at the forefront of modern canyoning techniques.
