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.

The Puente de Uzún is the only way across the Rio Salazar. In summer, it's a great place for swimming.

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.

A fantastic gorge with everything that goes with it: wild water, steep cliffs, tunnels that you can walk or drive through. It's very important to have a flashlight with you.

Riding into total darkness. It initially felt a bit scary to me. Not knowing at all what to expect. The secludedness is what made it so special I guess. The daylight and the canyon at the end the reward. Enjoy!

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
