A simply wonderful place, easy to reach from the Carpanè-Valstagna station, following a well-marked path along the Brenta River. The staff was equally fantastic, allowing us to follow the cave tour in both Italian and English (part of my group didn't speak Italian). I recommend going in spring; it's cooler and there's usually less traffic, so you can enjoy it all better. ;)

Road that overlooks a deep gorge of the Cismon torrent. The old asphalt road is currently closed for works and it is very difficult to cross the torrent on the dam wall

Old road that runs alongside the infamous "strada statale 50 del Grappa e del Passo Rolle" and reaches the border with Trentino-Alto Adige. It is one of the most well-known and appreciated mountain roads in the Alps, especially for the suggestive scenarios and natural landscapes in which its route winds.

The Oliero caves are a complex of caverns located on the slopes of the Sette Comuni plateau, near the hamlet of Oliero (municipality of Valbrenta). Much of the water that penetrates through the plateau above flows from the caves, a classic example of karst phenomena. There are four caves currently open to the public: Covol dei Veci and Covol dei Siori from which the Oliero river flows; while the two upper ones, Covol dei Assassini and Covol dee Soree, are now dry. To visit the caves it is necessary to have a ticket and entry is allowed only with a guide. In the park of the caves it is also possible to visit the museum of speleology and karst phenomena and relax at the bike grill bar.
