The bridge and its surroundings are very pleasant. The bike route after the fountain becomes impassable due to the undergrowth. It is advisable to return to the village and take the Camino along the track.

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.

Recommended route for the surroundings and the views, be physically prepared, the climb to Alto d Izco is hard, lunch at the top and return💪

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!
