サン・マロ・ドゥ・ゲルサックの天然記念物・トップ4

This megalithic tomb, built around 4300 BC, is the oldest monument in Loire Atlantique, dating back over 6,000 years.

Situated in the middle of a field in the village of Bergon. The road to it is well signposted and ends in a gravel path. Good for cycling

Unfortunately, you have to pre-book a time slot. Attention: Access to the many paths south of the house is only guided!!

This 6,000-year-old Neolithic burial mound is worth a visit. It is open for guided tours in July and August, if there is something you want to do after your run is over.

Discovered in 1873, the Dissignac Tumulus is a burial mound five kilometers west of Saint-Nazaire in the Loire-Atlantique department in the Pays de la Loire region of France. It covers two dolmens with parallel corridors, each eleven meters long. (@wikipedia)

Crossac is a small village known for its surrounding menhirs, such as the Barbière dolmen or the Bois Hoël menhir. The town itself has small shops of basic necessities (bakery, delicatessen, pharmacy). Gateway to the Brière, the village is also crossed by the famous GR 3.

I strongly advise against taking these trails before the summer! We tested them on May 20. It was just awful! You had to push our bikes in several places where the mud and the muddy water reached our knees. We did 1.5 km in 30 minutes. I don't wish that on anyone.
