El Pan Perdido, at 1.235 m above sea-level, is the highest and most westerly peak in the Sierra de Oña, which runs east to west, bordering part of the plains of La Bureba in Burgos, it forms part of the Natural Park of the Obarenes mountains, as well as the Site of Community Importance (SCI) and the Special Protection Area for Birds (SPAB) which go by the same name.

 This is a circular route which starts and finishes in the municipality of Quintanaélez, and it passes through the settlements of Soto de Bureba and Navas de Bureba with their interesting Roman remains.

The main attraction of the route is the ascent to the ridge of Pan Perdido through an area of Holm Oak woods to the east of the summit, from which the rough rocky crest is visible, from here it is easy to observe birds of prey such as the Egyptian Vulture, the Golden Eagle, the Griffon Vulture, and the Chough. On reaching the ridge we continue along it to the west until we come to a saddle from where we can easily descend to Navas de Bureba.
