Highly exposed route of intermediate difficulty, often used as the starting or ending section of the Bocchette Alte itinerary. Calls for physical fitness and a head for heights.

The Oliva Detassis via ferrata takes you from Bocchetta Bassa dei Massodi to the Brentei hanging glacier and runs beneath the west ridge of Cima Molveno. Well equipped with cables and long vertical ladders, it climbs over a wall of rock about a hundred meters tall up cliff faces and along narrow ledges that require athletic skill and endurance.

Running above the former Brenta hanging glacier, the trail has been dedicated to Oliva Detassis by her sons, Bruno, Giordano and Catullo Detassis. The actual via ferrata is an outing of between 2 to 3 hours, but you will also need to take account of the time it takes for the round trip to and from the trail itself (which adds another 4-6 hours).

Author’s recommendation

The lengthy series of rungs up exposed, vertical cliff faces make this itinerary physically challenging. Surface can be wet even in late summer.

Turn-by-turn directions

From Spallone dei Massodi, head down along ledges and chimneys using the cords and handholds provided until you reach Bocca Bassa dei Massodi, a section of trail dedicated to Mario Chioggiola.

At Bocca Bassa dei Massodi, you will find a fork in the trail. The section of via ferrata dedicated to Umberto Quintavalle heads down to the left and will take you to the shoulder of Cima Molveno (2,915m / 9,564 ft) and on to the Sfulmini hanging glacier and Rifugio Alimonta (2,580m / 8,465 ft). Down to the right, on the other hand, you will follow the Oliva Detassis via ferrata no. O396, which takes you to the Brentei hanging glacier.

This via ferrata features 8 series of iron rungs, including the most vertical and most exposed of the group, which together connect the various ledges and enable you to descend roughly 100 meters (330 ft) very quickly. The trail is dedicated to Oliva Detassis, the mother of Bruno, Catullo and Giordano Detassis, who dedicated this trail to their mother and to all the mothers of mountaineers, who are forced to share their children’s love with the mountains.

From the Brentei hanging glacier, you can get to Rifugio Alimonta (2,580m / 8,465 ft) by heading around Cima Molveno and Due Gemelli, or you can head down to Rifugio Brentei (2,182m / 7,159 ft).
