Peña del Oso

Peña del Oso is a summit in the Sierra de Guadarrama reaching about 2,196 meters (7,205 feet) in Segovia province. The peak rises as a granite formation within the central range, accessible through various trails that wind through the mountain landscape.

The summit formed from granite geology that has been exploited since past centuries. A quarry on the southern face supplied local communities with stone for buildings and construction throughout history.

The summit is part of the La Mujer Muerta chain, where the silhouette resembles crossed hands when viewed from the Segovia plain. This visual identity has shaped how locals and visitors perceive the surrounding landscape.

The easiest access starts from Navas de Riofrío, where trails climb through forest and open terrain toward the peak. Weather can shift quickly at this elevation, so sturdy footwear and appropriate clothing help ensure a safe and comfortable hike.

The summit displays a granite sculpture of a bear, a local landmark that catches visitors by surprise. The northern face contains one of the largest boulder fields in the entire mountain range, a geological feature that sets it apart.
