One of the most peculiar places you can find in the Belluno Dolomites, and almost nobody knows it. The Bus del Buson is a fossil gorge: very high and smooth rock walls, total silence, no water — the Ardo stream changed its course millennia ago, leaving this canyon suspended in time. Short (approx. 1.5 hours) but challenging loop trail: the descent to the gorge is steep and the ground is slippery even in dry weather. Trekking shoes are essential, poles are recommended. To be avoided in rain or frost.

It is also called Bus de la S'cesòra (notch): it is a cut in the rock, which proceeds between rocky walls that almost touch each other. This gorge was carved by a subglacial torrent, about 15 thousand years ago. A landslide diverted the torrent that left the gorge, carving out a new path parallel to the original one: in fact the Ardo flows 150 meters lower

The Brent de l'Art are gorges delimited by rock walls, dug over time by the Ardo torrent. They derive from a change in the course of the Ardo, which occurred due to the clogging of the original riverbed by a landslide

The Caglieron caves are located in the municipality of Fregona, province of Treviso, precisely in the locality of Breda. It is a series of cavities created partly by natural erosion and partly by human action.

Once out of the Canyons, go up slightly until you reach a crossroads: follow the signs for Rifugio VII Alpini

The most popular canyon is Brent de l'Art, known for its deep ravines and striking red rock formations. Another significant site is the Bus del Buson Gorge, an ancient riverbed now walkable. You can also explore the Val Falcina Nature Trail, which follows a fluvial incision, and the Caglieron Caves, featuring both natural and human-made cavities with waterfalls.
The Brent de l'Art is renowned for its 'Cretaceous Red Flake' rock, formed 90 to 65 million years ago and rich in iron oxides, giving it a characteristic red color. Millions of years of water erosion by the Ardo stream have carved steep walls, revealing these ancient layers and creating artistically shaped rock formations and emerald pools.
