Fresneda de la Sierra Tirón is a small town in Burgos, located in the heart of the Sierra de la Demanda, very close to La Rioja. It is an attractive destination for hikers due to its mountainous surroundings and the proximity of places like Pozo Negro, a turquoise glacial lagoon in the shadow of Otero Peak. The town preserves historical remains and traditions, with the Church of the Assumption and hermitages as points of interest. From here, trails depart to peaks such as Otero, Cabeza Aguílez, and Torocuervo, ideal for enjoying panoramic views and beech and oak forests.

The abbey complex is a dream: 13th century and really well preserved. Unfortunately, the interior has little spiritual impact due to the latticework and the large burial chamber in the center of the room.

The monastery is an interesting place to spend the night, and has a very small bar and café, but the albergue El Descanso de San Juan by the side of the monastery has lovely pizzas

The area used to be impassable and feared due to gangs of robbers. The monastery offers a pilgrims' hostel.
