Laguna Larga is one of the glacial lagoons found in the Urbión Mountains, very close to the famous Laguna Negra, in the province of Soria. It's less well-known but equally impressive, and is part of a natural environment of great beauty and ecological value.

Pico de Urbión is an ideal destination for hiking lovers. It is located between the autonomous community of La Rioja and the provinces of Soria and Burgos (Castilla y León). It limits to the north with the Najerilla valley, to the south with the Duero valley, to the west with the Neila mountain range, and to the east with the Cebollera mountain range.

In the Laguna Negra de Vinuesa there are two Portillas that allow climbing to both ends, right and left, of the cliff that surrounds it. The Portilla on the Right side allows the climb towards Pico del Zorraquín. The Portilla de la Izquierda, shorter and easier to climb, puts you on the path to climb the Pico de Urbión, either through the Laguna Larga or the Laguna Helada. On the way up to this Portilla you will find the Arroyo de La Laguna with its beautiful waterfall, where it is essential to stop to admire and photograph it.

To climb from Laguna Negra to Pico de Urbion, please wear suitable footwear for trail or mountain... do not go with beach flip-flops as I have already seen more than one and more than two sprains due to this imprudence.

At this point we are at the highest peak in the province of Soria. Pico Urbión, located at 2,228 meters above sea level, offers excellent panoramic views wherever we look. All the trails that bring us to the top are great for running and hiking.

Less known, but just as beautiful as the Black Lagoon. It is a lagoon of glacial origin that is worth visiting if we are in the area.

Parking availability varies by monument. For the Source of the Duero River and nearby Picos de Urbión, it's recommended to drive from Duruelo to the bunker parking lot and continue on foot. The Dinosaur Footprints site is located directly within Regumiel de la Sierra, suggesting local parking options. For other trails and natural areas, look for designated parking areas at trailheads, which are often dirt roads leading to the start of routes.
When exploring the natural monuments, especially if you plan to hike, wear appropriate footwear such as hiking boots or sturdy trail shoes, particularly for routes involving uneven or rocky terrain like those near the Laguna Negra or Pico de Urbión.

The time required to visit varies. The Dinosaur Footprints site can be explored in a relatively short time, perhaps 1-2 hours, depending on your interest level. A visit to the Cueva de Covarnantes might take a few hours, especially if you include a picnic. For more extensive sites like Pico de Urbión or the glacial lagoons, a full day or a significant portion of it would be needed to hike and fully appreciate the surroundings.
