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.

It is a short but interesting walk. Going clockwise there is a possibility to swim shortly after the tunnel. The water is very cold

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.

Beautiful gorge to visit. You can spot blue rock thrushes and large numbers of griffon vultures here. Sometimes other vultures can also be seen. You can catch a glimpse of the river and see some rafting boats passing by. it's a pleasant surprise when you emerge from the railway tunnels.
