A biking loop in Cheese land
The starting point from Saint-Affrique is via the green lane in the direction of the St-Jean d’Alcas battlements.
Then the ascent towards the Aiguières pass will offer you a magnificent view over the Tournemire amphitheatre before beginning the downhill section that goes to Roquefort  (indulge yourself with a small tasting session of Roquefort cheese and a visit to the caves).
At last, the Combalou trail marks the way back to Saint-Affrique with a passage through the land of Tiergues and Crassous dolmens

Tiergues dolmen
Listed as a historical monument, the Tiergues dolmen is part of the 20 or so dolmens which have been recorded in the area, some of them being poorly-preserved. The excavations of these megaliths were carried out by Emile Cartailhac during the 20th century and today their artefacts are scattered throughout Midi- Pyrennées (Rodez, Toulouse…)

Crassous dolmen
This dolmen which can be seen from the road is one of the dolmens that is worth making a detour to visit. It is nicknamed l’Ercoule owing to an old legend that the demigod Hercules, known for his superhuman strength, must have built this burial chamber.
