This is a basalt ravine just south of a dam. The routes vary from easy slabs to an 8b+ overhang. The rock is of decent quality with some flakes here and there. You can climb here all year around. In the summer it is best climbed in the afternoon when the crag will be in the shade.
One of the most popular crags of the island, and an old one too. Some grades might feel stiff compared to other areas.
The guide book does not provide information about each climb apart from the grade.
Take the GC-60/GC-520 and follow it for about 11Km (and camel parks) take Left turn GC-602 downhill towards Presa Ayagaures. At the bridge (27.865951, -15.568152), leave the road and take the dirt track to white buildings (about 1km from road). Road is very bumpy with many loose stones, so be mindful if you're on a rental car. (Parking : 27.873109,-15.566646)
The main path listed in the guidebook, via the dam, is no longer of use as the stairs have crumbled away.
