Grottes de Saint Christophe
A cave sculpted by glacial waters, where vast halls follow one another, riddled with giants' kettles. Its concretions, like those of the Mont Blanc dome, will amaze you. You can also discover the Sardinian Way, and its monument raised by Charles Emmanuel II in the seventeenth century. This old royal road linked Lyon and Chambéry. And do not forget to cross the Pont Saint-Romain, a picturesque little stone bridge spanning the Guiers Vif gorge, the old border between the States of Savoy and the Kingdom of France.
