Just after leaving the parking lot, about 300 meters away, take the detour to the left and follow the path very easily and beautifully. If you have decent binoculars, you can see some chicks in the vulture colonies, depending on the time of year, and some adults all year round. Highly recommended, short and sweet.

Access from the pass is simple, along a good path through beech forest, the Paso del Oso, a natural window, is not dangerous in itself, unless you lean too far out; there are people who stand at the top for photos.

There is very little shade on the entire circular route, only the last, short section in the gorge has shade. In summer it can get as hot as 40 degrees Celsius and then only the section in the gorge is recommended, not the circular hike.

This is one of the hotspots for wild and free-flying vultures. I counted 16 of them. With their wingspan of almost 3 meters, they can be easily observed with the naked eye in the Foz de Lombier gorge.

A very nice gorge to visit. We didn't expect. The many vultures that sat on the edges of the canyon were an added value
