Mer de Pierres

- The route starts from the village of COLLONGE-EN-CHAROLLAIS, where parking is available near the town hall and village hall. We recommend that you make a short diversions to the church, which was restored a few years ago.
- This walk has a steep gradient, particularly at the start (uphill) and the end (downhill). We advise you to take the walk in a clockwise direction (from "Les Justices").
- You'll gradually move from meadows to a recently logged forest, where you can stop off at an old telegraph station.
- The path you follow gradually becomes narrower and stonier until you enter an unlogged forest. On this part of the route, we advise you not to leave the waymarked path if you don't want to get lost in this exceptional natural environment.
- You will wind your way through what is known locally as the Sea of Stones before returning to the village. On the way down, you'll enjoy some great views over the Guye Valley.
