Located in the Ojo Guareña Natural Monument. In the first section, the path runs along a slope covered by holm oaks, bringing us closer to the spectacular natural bridge "El Ventanón". From there we descend along a track to the town of Villamartín. In the challenging rocky cut we discovered El Ventanón, an impressive natural arch 30 meters wide and 20 meters high. Its origin is due to the passage of an ancient water conduit that dissolved the limestone over the centuries. Today, through this whim of nature we observe the mountains of Somo and Merindad de Valdeporres. Villamartín preserves popular architecture linked to farm work.
