Sports and leisure activities Collonge-En-Charollais

The Mer de pierres (Sea of Stones) at Collonge-en-Charollais is a geological curiosity well worth a stroll. Starting from the village center, you'll have to cover a 6 km round trip and climb 200 m to admire these chaotic rocky expanses lost in the middle of the forest, along the GR7. It's a pleasant walk, in the shade and with great views, in these woods where, in 1944, one of the many Resistance maquis was organized. To avoid the first part, drive to the end of rue de la Varenne, then follow the AMSV1 signs.
