Castello di Betty 

The Castello di Betty is a vertical wall with crimp. The equipment has been financed by the nice owner of the B&B of Villamssargia, the Msr. Betty.

From the center of Domusnovas follow Cagliari street in direction Musei. Once you left Domusnovas, you come to a roundabout, take the third exit (not Musei and Vallermosa) and continue for a few kilometres. Just before the road becomes dirt, take the left turn, there’s the signal to the cave of San Giovanni.
Few meters before the cave, take a trail on the left that rises steeply pointing directly to the cave Tana delle Tigri, already visible from below, about at the middle of the path (before to arrive to Chemical Area) there is a little path on the right, follow the trail for few minutes and you arrive at the crag Castello di Betty.
