Gréalou

Grealou is one of the larger settlements on the causse, about 300 inhabitants gathered where a water source emerges through the limestone. That water explains why there's a village here at all.

The area around Grealou has an extraordinary concentration of prehistoric megaliths. The Dolmens de Pech Laglaire, three dolmens grouped within 200 m on the highest point of the causse, sit directly on the GR65. Dolmen No. 2 is a UNESCO World Heritage site, classified as part of the Routes of Santiago de Compostela in France. Its capstone weighs an estimated 7 tonnes. The site was used as a communal burial chamber during the Neolithic, and later excavations at the nearby Dolmen des Aguals uncovered a cremation necropolis from the early Iron Age and a copper dagger that appears to have been traded from lower Languedoc, evidence of commercial exchange with the Mediterranean coast over 4,000 years ago.

The village has a small grocery store, though hours are unreliable. There's a gite d'etape and water is available. This is the only place between Beduer and Cajarc where you can reliably resupply.
