The Valle Cavanata Nature Reserve is a protected area of exceptional natural value located in the eastern part of the Grado lagoon. Once used as a fishing valley, it is now a wetland of international importance (Ramsar Site) dedicated to biodiversity conservation. The heart of the reserve is a vast brackish lagoon surrounded by reed beds and hygrophilous woods, which serves as a refuge and resting area for thousands of migratory birds, including the famous pink flamingos and numerous species of ducks. Accessible via flat paths and cycle paths, the reserve offers several observation huts for birdwatching, allowing you to immerse yourself in a silence broken only by the calls of the fauna, just a few kilometers from the sea.

Looking for the Montelonga mountain hut that for the umpteenth time I didn't find. Don't follow this trail unless you want to take a difficult path on foot and carry your bike for about 30 minutes. For the rest, the forest road is wonderful, all under the trees with concrete ramps of over 25%. For the record, we saw foxes, owls and roe deers up close.

The small reservoir at the Nassfeld pass is beautiful, but unfortunately overrun by camper vans and motorcyclists on weekends.
