The Rettilario is a small crag placed immediately to the left of the Guggenheim’s Grotta; it is a wall slightly overhanging with compact rock, with various colors, from white to red to grey. The climbing’s kind is the classic of Val Pennavaire: resistance, with some more intense passages of fingers.
If you are climbing the Guggenheim, thanks to the Rettilario you have an extra climbing option, which is not as "poisonous" as it might seem!
Approach
From the Guggenheim’s Grotta take the path to the extreme left that going up and will take you in two minutes to the base of the crag.
