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.

A comfortable mountain pass that connects the provinces of Burgos and La Rioja. Both sides have beautiful views, and it is worth climbing both.
