Climbing on the Thaurac
A well-known limestone crag, minutes from the property.

The Thaurac is a climbing venue known well beyond the department. The limestone is compact and sculpted, with the mix of water pockets, holes and crimps typical of Languedoc crags, and the aspect allows climbing for much of the year.
What makes it work for a group is its size: there are many sectors covering a very wide range of grades, from genuinely accessible 4s and 5s to hard routes that draw climbers from a long way off. In practice a beginner and an experienced climber can spend the same day at the same crag without either being bored or out of their depth.
Most routes are single-pitch sport climbs, which keeps the logistics simple: one rope, a set of quickdraws, something to belay with, and you can work through several routes in a morning. A few sectors offer multi-pitch routes for anyone wanting a full day out.
If nobody in the group already climbs, do not head off alone with hired gear: crag climbing requires belaying skills that cannot be improvised in an afternoon. The local guiding offices run introductory sessions, and that is by far the better way in. If on the other hand you have independent climbers among you, the local guidebook and a bit of scouting are enough.
It is also, very practically, the easiest activity to fit into a busy weekend: the crag is close enough that a pair can go climbing at first light and be back for breakfast while the rest of the group is still asleep.
