Sierra de Urbión

Sierra de Urbión is a mountain range in northern Soria Province with steep peaks, pine woodland, and glacial lakes scattered across its terrain. The landscape transitions from dense forest on lower slopes to rocky terrain and open slopes at higher elevations.

The range serves as the source point for the Duero River, one of the major river systems of the Iberian Peninsula. This geographic role has long connected the highlands to broader regional water networks and settlements downstream.

The Black Lagoon carries local folklore in its name and has inspired regional writers to explore themes tied to mountain life. Today, visitors encounter this connection between landscape and storytelling when walking through these highlands.

The main access routes run from Soria through regional roads toward the village of Vinuesa, which serves as the typical starting point for hikes into the higher terrain. Plan visits during late spring through early autumn when conditions are most manageable, as winter weather makes trails harder to navigate.

Rare populations of native crayfish survive in specific streams and springs within these mountains, representing one of the last refuges for the species in the region. These freshwater creatures inhabit only the coldest, cleanest water sources, making their presence a sign of the area's ecological health.
