At this developed natural site in Seythenex, you can visit the only underground gallery open to the public in Haute-Savoie.
A network of galleries and tunnels accessible over 250 meters, waiting to be explored during a 40-minute guided underground tour… at a temperature of 10°C.
You can also admire the waterfall, where the tumultuous waters of the St Ruph plunge nearly 45 meters.
You can even try the 150-meter-long zip line, suspended 40 meters above the ground… guaranteed thrills! A dynamic and welcoming team supervises these activities. And finally, you can relax on the terrace while enjoying a local specialty.
