The activities we offer



Grotte de Choranche

You will follow your guide along a fitted-out route, where the galleries light up as you advance. All year round, discover this underground world with its fairy-tale lighting, its thousands of straw stalactites and its olms.


Jardin des Fontaines Pétrifiantes

A garden conceived and designed to showcase more than 800 plant varieties from all over the world. The water, flora and repurposed objects create unusual trails. The gardeners will guide you in discovering this world, and happily answer your questions.


Paddlewheel Boat

Sail along the River Isère to discover the wildlife, flora and heritage monuments along its banks. A friendly and tranquil interlude interspersed with the crew’s commentary, as they share history and anecdotes.

The cruise lasts 1hr to 1hr30, depending on the season, between Saint-Nazaire-en-Royans and La Sône. On arrival, your coach is waiting. 


Grotte de Thaïs

Accompanied by a guide, you explore a labyrinth dotted by hollows and by red and black concretions. Journey back in time, and find out about the Prehistoric humans who settled here at the end of the last Ice Age.
