This is the biggest wall in Valle del Vero and climbers like Matteoli, one of the pioneers who set up the first route in the area, have been coming here since the 1970s. No other routes were opened until 2005, when Andrea Giorda from Turin started setting up routes from the bottom up. Some of his routes, Hotel Varatella and Panoramica for instance, are already becoming classic routes many climbers can try, while other routes require some preparation: Wall Rats and G.T for instance. At the base of the Rocca there are several new monopitch sectors. On the left there are the varied rock of Sasso del Rio, mainly routes in the 6 grade, then the wonderful Grotta dell’Ulivo with 7 grade routes, perfect for climbers in excellent shape; then Antro degli Spettri - a new sector - with a sharp wall and wonderful overhanging routes (between 7 and 8 grade). On the right there is Placca Curzio with enjoyable slab routes, and finally Giardino del Re with overhanging tufas and higher grades. Above this last sector there are Belvedere and Arena.
If one continues from the Giardino del Re up some rocky ramps (fixed rope) one shortly reaches the sectors Arena and after that the Belvedere.
From the square walk up to the path ”Sentiero delle Terre Alte” which parts behind the ticket office and follow this path for about 15 minutes until the base of the crag close to the west arête. A short deviation leads to the sector Sasso del Rio hidden among the trees. Walk back up on the right (signposted for Arena-Belvedere) along the cliff to reach the Grotta dell’Ulivo. Higher up the mountain lie the Antro degli Spettri, Placca Curzio and the Giardino del Re (20 minutes from the car park to reach this sector).
From Toirano drive towards the head of the valley along the SP1. Immediately after the village follow the junction on the right towards Boissano. Pass the bridge, continue left towards the cave and reach the parking lot of the cave after a couple of hundred metres.
