Bivacco Aldo Frattini, Mountain shelter in Valbondione, Italy.

Bivacco Aldo Frattini is a metal construction of about 3.5 by 2.5 metres, placed by the CAI of Bergamo on the crest between Valsecca and the Piani del Campo valley, just below the Valsecca pass. It rests on the ground, stabilised with wooden planks and steel tie rods, and fixed with ropes on its sides. Inside are nine folding bunks, three stools, a table, a gas stove, a pantry with food, and a first aid kit.

This shelter was built by the Italian Alpine Club to provide basic support for mountaineers exploring remote peaks in the region. Its construction reflects the long tradition of creating simple refuges at high altitude across the Italian Alps.

This shelter serves as a meeting point for mountaineers and hikers crossing the Orobie Alps during their journeys. People stop here to rest and connect with others pursuing mountain activities in this remote area.

The shelter is open year-round and managed by CAI Bergamo, with free access for all visitors. It is a basic structure without heating or food service, so visitors need proper mountain gear and self-sufficiency to stay safe.

The hut is held down by ropes on its sides and steadied with wooden planks and steel tie rods, a response to wind on the crest. Inside, a pantry holds food supplies and a first aid kit with medicines, and a stove runs off a gas cylinder. Nine folding bunks, three stools and a table fill the 3.5 by 2.5 metre cabin.
