Superb view of Ambialet and its peninsula, created naturally by a meander of the Tarn, which embraces it for three kilometers. It is dominated by an old priory, perched on a shale ridge. At the level of the dam, the narrowest isthmus in Europe is located!

The Tarn valley is steep enough that leaving it involves a nice climb, 5 to 6 km with passages at 10%. And multiple routes around Ambialet.

As you come down the D74 road and around the last corner before entering town, you get a splendid view of the village of Ambialet and the old hilltop Cathar fortress. Both look as if they have naturally emerged from the local rock-bed over the past few centuries. There is one restaurant and two cafes in town as well as a cafe and small hotel just over the bridge on the other side of town.

Ruins of a medieval village abandoned in the 16th century and lost in the forest. You can still see the remains of the old mill, including huge millstones, as well as a little higher the remains of the Labastide Vassals keep which once dominated the old medieval village.
