The Creux du Van is a natural rocky cirque approximately 1,400 metres wide and 150 metres deep, on the north side of Le Soliat, in the Val de Travers district in the Swiss canton of Neuchâtel. A very well known, amphitheatre-shaped natural attraction, it is at the heart of a nature reservation area of 15.5 km2.

Geology

The rocky arc of Creux du Van was created in three phases: Phase 1: A glacier covered the area of today's Val de Travers around 140,000 years ago (Würm Ice Age). The stream of meltwater eroded material, making a V-shaped valley. Phase 2: During subsequent ice ages, other glaciers were created and hollowed out the valley. In warmer periods, the material was eroded by meltwater. Phase 3: After the removal of rocks from the fault, erosion of a stronger layer from a different age was much slower. See cirque for a description of the process forming features like this. The ground beneath the Creux du Van remains permanently frozen to this day (permafrost).

Attraction

Ibex were introduced in the area in 1965. , there are 17.

Access

The summit area can be reached on foot or by car. A paved road from Saint-Aubin-Sauges (on Lake Neuchâtel) or Couvet (Val-de-Travers) climbs to la ferme du Soliat (1,382 m), a few minutes walk away from the summit of the rocky cirque. Some hiking paths are signposted, via les petites Fauconnières. Notable trails in the areas include:
