A hill located below the summit of the same name as the Saja reserve, resting on a ridge of gentle elevations above the Cabuérniga valley. These Saja mountains are often known as the Sierra de Bárcena Mayor, due to the town that lies at its feet at an altitude of 534 metres. In ancient times, the so-called Camino de Castilla or Reinosa road crossed this ridge towards the lands of Campoo. From Los Tojos (636 m) and Colsa (729 m) the ridge was reached at the Venta Vieja hill (1152 m), where one of the many inns that awaited the traveller along the way was located.

At 2029 meters above sea level, the top of Peña Labra is located in a privileged place. It represents the border between the Community of Cantabria and Castilla y León, so to the north you will have impressive views of the Cantabrian interior and the mountains of the Picos de Europa National Park, while to the south you will be able to appreciate another wonderful landscape such as the of the Montaña Palencia Natural Park. Crowning its peak is for the most daring, very technical sectors and not suitable for those who suffer from vertigo, but it has a great reward.

Absolutely. For hikers, the ascent to Peña Labra is considered challenging with very technical sectors.

Many MTB trails in the region are also rated as difficult, offering significant challenges.
The best time to visit Sierra Del Cordel largely depends on your planned activities. For hiking and cycling, late spring (May-June) and early autumn (September-October) generally offer pleasant temperatures and stable weather conditions. During these periods, you can avoid the intense heat of summer and the snow and ice of winter, which can make higher elevations inaccessible or require specialized gear.

The area is part of the Natura 2000 network and recognized as a Special Protection Area for birds. Efforts are underway for brown bear recovery, including planting apple trees for their sustenance. You might also encounter various bat species and invertebrates indicative of mature forests.
The high-altitude pastures of Puertos de Sejos have historically supported extensive transhumant livestock farming for centuries, reflecting a significant cultural aspect of the area. Ancient human presence is suggested by mentions of the 'Ídolo de Sejos' and 'Menhires de Sejos' in connection with this area, hinting at deep historical roots in the landscape.
The Sierra Del Cordel is primarily composed of very hard sandy conglomerates from the Triassic period. These highly resistant strata lead to the formation of large erratic blocks, such as the distinctive 'cantos de la Borrica' found in the Puertos de Sejos. Limited granite outcrops can also be observed within the range.
Visitors frequently highlight the breathtaking panoramic views from peaks like Tres Mares Peak and Peña Labra, which offer vistas stretching across the Cantabrian interior, Picos de Europa, and Montaña Palentina Natural Park. The scenic beauty of passes like Palombera Pass and the challenging yet rewarding climbs are also highly appreciated by the komoot community.
While some routes can be challenging, there are options suitable for families. Look for trails with 'easy' difficulty grades, such as the 'Tres Mares loop from Estación de Esquí y Montaña Alto Campoo' mentioned in the Hiking in Sierra Del Cordel guide. These often involve less elevation gain and shorter distances, allowing families to enjoy the natural beauty at a comfortable pace.
