Valdecebollas, Mountain summit in Montaña Palentina, Spain

Valdecebollas is a 2144-metre summit in the Montaña Palentina, on the southern buttress of the Sierra de Híjar, known on this slope as Sierra de Peña Labra. Its top holds the Torreón, a small cylindrical stepped stone tower with a plaque, a summit book and a triangulation station at 2139 m. It closes the northern side of the Covarrés glacier cirque, source of the Pisuerga.

The summit's stone Torreón, a small stepped cylindrical tower with a plaque, a summit book and a triangulation station, is the reference point for the mountain's recorded history. Since 1965 a mass has been held there on the first Sunday in August, organized by residents of Barruelo and Brañosera and attended by mountaineers from Campoo and La Pernía. The peak marks the eastern boundary of the Montaña Palentina.

On the first Sunday of August, residents from nearby villages gather at the peak for a traditional mass celebration that has taken place since 1965. This ritual shows how deeply the surrounding communities are connected to this mountain.

The ascent begins from the village of Brañosera and follows a mountain path that passes through El Golobar at 1840 meters before reaching the summit. The route is walkable but requires sturdy footwear and moderate fitness.

The glacier cirque of Covarrés on the mountain's northern slope is the source of the Pisuerga River. Its water sinks at the Sel de la Fuente sinkhole and resurfaces three kilometres lower at the Cueva del Cobre, near Santa María de Redondo.
