These are one of the less visited megalithic sites in Brittany and one of the places where it is possible to wander freely among the stones.
They are ignored by most of the guide books which just concentrate on the megalithic remains around Carnac. The stones are just off the D776 road between Malestroit and Guer, and are signed about 2km beyond the small settlement of Monteneuf.
There is a large car park on the opposite side of the road which is used by walkers as there are many tracks through the woodland.
There are a large number of standing stones are set in an open heathland setting with heather. In mid September there was free access to the site. The box containing information leaflets was empty. There are a few information boards around the site in French.
You are able to walk among the stones. Some are massive. The biggest is 5m tall and weighs 38 tonnes. Some are arranged in lines; others are a more random distribution. There was a short row of quite small stones.
A quarry site is identified which shows how the blocks of stones were chipped out. Grooves were carved out and wooden wedges pushed in to split the rocks.
There is an area with a reconstructed dolmen and partially reconstructed neolithic house of wattle and daub.
There are no amenities at the site, which is one of its attractions. It is also easy to walk around and suitable for people with limited mobility.
The stones are in a delightful setting and we were pleased we had made the effort to visit.
