On the border between France and Switzerland - you can easily crag on both sides in a day. Great technical granite - mostly less than vertical, though some pumpy overhangs as well. Lots of bolted multipitch up to ten pitches as well as single pitch sport. The longer routes (especially the older ones) tend to be a bit more sparingly bolted, but it's still plaisir climbing.

Depending on the area you're going to , park either near Barberine on the French side (just before the border - don't park in the village itself, but rather just as you pull off in the marked "visiteur" parking) or Châtelard on the Swiss side (park behind the "Hotel Swiss" right at the border and take the signed path towards Gietroz).
