Forêt Adrénaline shares its must-see attractions and activities to enjoy during a day trip or a longer stay in the Morbihan region.
The Carnac stone alignments : a must-see during your stay
No visit to Carnac would be complete without discovering its famous standing stone alignments. Le Ménec, Kermario and Kerlescan are home to more than 3,000 standing stones spread across approximately 4 kilometres. These remarkable sites are true treasures of the region’s Neolithic heritage!
Since 2025, the “Megaliths of Carnac and the shores of Morbihan” have also been listed as a UNESCO World Heritage Site.
Carnac’s beaches and Quiberon Bay
After exploring ancient stones, it’s time to enjoy the seaside! Carnac has five beaches:
- Grande Plage (the best-known beach);
- Légenèse;
- Ty Bihan;
- Saint-Colomban (particularly popular for water sports);
- Beaumer.
Depending on the season, you can enjoy swimming, coastal walks, water sports or simply relax while taking in the ocean views.
Saint-Michel Tumulus and the Museum of Prehistory
Another must-see is Saint-Michel Tumulus. Measuring 125 metres long and 60 metres wide, this burial mound overlooks Carnac. From the top, you can enjoy beautiful views of the town, Quiberon Bay and the surrounding landscapes.
To discover more about the region’s history and heritage, head to the Carnac Museum of Prehistory, located in the town centre. You’ll find an impressive collection of artefacts uncovered during excavations at local megalithic sites.
