In the center of the photo, the mountain pass is called "Passo Principe", and there is a small Refugio hidden near the rocks, just left of the pass. You can see the access trail to the Refugio on the left.
The mountain on the right is Catinaccio d'Antermoia, and it is equipped with a nice Via Ferrata.
Via Ferratas are climbing routes permanently equipped with a safety cable. For more info about via ferrata, go to en.wikipedia.org/wiki/Via_ferrata.
