Laguna Negra and Circos Glaciares de Urbión Natural Park, Natural park with glacial lakes in Soria Province, Spain
This natural park spans three municipalities and features a dark mountain lake surrounded by steep cliffs and dense pine forests. The landscape displays typical glacial forms including cirques, valleys, and multiple lakes that were shaped by ancient ice masses.
During the Quaternary glacial period, massive ice masses carved the mountain landscape, leaving behind cirques, lakes, and deep valleys. This glacial process created the geological features that define the area today.
The lake's name refers to its dark waters, a feature that has captured people's imagination for generations. Today, visitors experience this striking landscape that continues to inspire both hikers and writers.
The area is accessible from three towns via marked hiking trails and can be visited year-round, with spring through autumn offering the best conditions. Visitors should bring sturdy footwear and weather-appropriate clothing, as mountain conditions can change quickly.
The highest point of the park, Urbión Peak, serves as the source of the Duero River and sits at over 2200 meters elevation. This mountainous region is home to rare plant species found nowhere else in the Pyrenean foothills.
