Pozo Negro is a glacial lake located at an altitude of 1,760 meters in the Sierra de la Demanda, within the Fresneda area of the Sierra Tirón. It is an isolated and difficult-to-access spot, making it a very attractive spot for hikers seeking unspoiled nature. Its cold, dark waters, protected by Otero Peak, are the source of the Tirón River and are home to unique species such as the endemic palmate newt. The route to the lake, from the Tres Aguas refuge, takes more than three hours, passing through beech forests and high mountain areas. Therefore, it is advisable to wear good footwear, and bring plenty of food and water.

Romanesque church dating back to the 12th century on the outskirts of Valgañón, a town in the Sierra de la Demanda near Ezcaray. A great stop to get water on the way up to the top of Pradilla.

With the mountain route you can go up from Fresneda, reach the Pozo Negro (durillo), and from there to the Cruz de la Demanda, returning to Fresneda by road and passing through the top of La Pradilla.

High mountain peak that is 1,855 meters high, located in the Sierra de la Demanda, right on the border between Castilla y León and La Rioja. A nice place to take a break and enjoy the natural beauty around you.

This church, reddish in color due to the limestone, dates from the 13th century and is Romanesque in style. It is one of the Rioja jewels belonging to this period. Water flows from the three springs from one of the most important aquifers in La Rioja. Water permeates through the sandstone, storing water throughout the year.

I am not at all religious and less a believer, but I thought it was a very interesting visit and above all the person who teaches it, who lives it, has a good job of documentation and archives of more than 10 centuries. Very nice historical anecdotes.
