Walk · about 4 km · low to medium difficulty · €20 with the monastery · waterfalls, lakes and caves among centuries-old trees

The Monasterio de Piedra park is a historic garden laid out in the canyon of the River Piedra: about 4 km of paths, steps and bridges among waterfalls, streams, lakes and caves, beneath centuries-old trees. The two places everyone comes to see are the Cola de Caballo (Horsetail) waterfall, more than 50 m high, and the Iris Cave, a cavern that opens up behind it.
Tickets and opening hours
The 2026 ticket includes the park and a self-guided visit to the monastery: €20 for adults, €14.20 for ages 4 to 11 and over-65s. Large families, 15% discount; Carné Joven, 25%. Under-14s cannot enter without an adult. The park is open from 9:00 to 17:45, with last entry at 16:30; from 10 November to 6 January, from 9:00 to 17:30 and last entry at 16:00. The ticket office, next to the shop, closes 15 minutes earlier. With the same ticket you can leave and re-enter on the same day, as long as you get it stamped first.
The route
The monastery rates the difficulty as low to medium: there are stretches of steps and slopes, and it is not fully accessible for pushchairs or wheelchairs. There are two signposted routes of different lengths; allow two to three hours to see it without rushing. You cannot eat inside: there are only vending machines in the lower part.
With a dog
Dogs may enter the park on a lead. In the monastery they are allowed only in a carrier or backpack, and they cannot enter the birds of prey area.
