This mountain biking tour you will permit to discover two relic of the past: the Rock of Caylus on which was built the castle overlooking the city and the Dolmen Tiergues historical monument.

It first follows a road, then a trail and eventually a singletrack rising gently up to the village of Tiergues where you will be able to enjoy a typical caussenarde architecture. The way back which goes along a ridge line provides a wonderful 360-degree view and a nice downhill ride to the Caylus Rock which overlooksSaint-Affrique.

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…)

The castle was destroyed in retaliation of Count of Caylus’ rebellion against his overlord Raymond VII, count of Toulouse, marquis of Provence and of Gothie.

From the F. Fabié square, take the D50 (usually called the graveyard road) for 2.5 km up to the Moulin du Juge.

  1. Before crossing the small bridge, take the path on the left hand side (2nd marker).
  2. Cycle up the vale to the road intersection close to the well known dolmen de Tiergues (it is a 2 km ride there and back to have a look at it). Then take a wide and steeper path which leads to the hamlet of Tiergues.
  3. When you leave the hamlet, cycle up to the crest of the path towards the East.

This section of the route provides you with beautiful views overthe surrounding landscape: the avant Causse du Larzac towards the East, the Monts de Lacaune to the South and the Rougier de Camares to the West. To the North, isthe village of Bouloc with its relay mast rising to more than 1000m above sea level marking the horizon. The way back to Saint-Affrique is mostly a descent except for the approach to the Rocher de Caylus which requires a little extra energy, but the discovery of this site, which resembles a petrified fortress watching over the “villotte” is worth the effort.
