Pico Frentes, Mountain summit in Fuentetoba, Spain.

Pico Frentes is a summit in the Sierra de La Llana or Sierra de Frentes, in the municipality of Fuentetoba, about 8 km from the city of Soria. It rises to 1375 m, and its rocky walls in Fuentetoba are used as a climbing school. The Golmayo River and the Cascada de la Toba spring from beneath its pointed peak.

The documented history of Pico Frentes is tied to Monte Valonsadero, the more than 3,000-hectare woodland that King Alfonso VIII gave to the city of Soria; the mountain forms its backdrop. The sierra itself is called Sierra de La Llana or Sierra de Frentes, and its highest point, the Alto de la Risca above Cidones, reaches 1,423 m. A resident of Fuentetoba supplied minerals and fossils that led to the recent discovery of water-filled caves inside the mountain.

The Sorian poet Virgilio Soria Montenegro dedicated a poem to Pico Frentes, and the peak appears in the literary output tied to Soria. The mountain rises above Fuentetoba, the village at its foot, and the Golmayo river and the Cascada de la Toba spring from beneath its pointed summit.

The summit is best reached via several marked hiking trails from central Soria that offer resting points along the way. Depending on the route chosen, the ascent typically takes between two and four hours and weather can change quickly at higher elevations.

The Golmayo River rises directly beneath the summit, and the Cascada de la Toba falls near Fuentetoba at about 1095 metres. A local resident of Fuentetoba supplied minerals and fossils that helped researchers discover water-filled caves inside the mountain.
