First stop in the Moros valley, and little brother of the Tejo, it is even more beautiful for me. It is surrounded by forest and the reflection of the water gives it exceptional beauty.

A beautiful landscape surrounding the reservoir created by the Frio River dam on the outskirts of Revenga. Enjoy the reflections of the pine trees and blue sky in the calm waters.

Among the most appreciated by the komoot community are Puente Alta Reservoir, known for its beautiful landscape and role as a vital water source, and La Aceña Reservoir, where visitors enjoy exploring its various perspectives by walking around it completely. The glacial lagoons of Peñalara, especially Laguna Grande de Peñalara, are also highly popular for their stunning alpine scenery and hiking opportunities.
Yes, the Sierra Norte de Guadarrama is home to several beautiful glacial lagoons, primarily within the Peñalara Massif. The most notable are Laguna Grande de Peñalara, the most visited, and Laguna de los Pájaros, the highest in the park. These offer breathtaking alpine scenery and are popular for hiking.
The region offers a variety of outdoor activities. You can enjoy hiking, with trails like the Descent to Embalse de la Aceña from Casa de la Cueva, which is also suitable for cycling. For more challenging routes, consider the mountain hikes or MTB trails available in the area. Fishing is also popular at places like Embalse de La Jarosa, which is regularly stocked with rainbow trout.
Absolutely. Puente Alta Reservoir and La Aceña Reservoir are both noted as family-friendly destinations. The area around Embalse de La Jarosa also offers tranquil nature walks through pine forests, suitable for families. The hike to Cascada del Purgatorio, while a bit longer, is also considered accessible and rewarding for families.
The best time to visit depends on your preferred activity. Spring is ideal for seeing the Cascada del Purgatorio waterfalls at their most spectacular due to snowmelt. For glacial lagoons like those in Peñalara, they remain frozen from December to March, offering a unique winter landscape, but hiking is popular in warmer months. Reservoirs like La Jarosa are pleasant for nature walks and fishing year-round, though bathing is prohibited.
You'll encounter diverse natural beauty. The glacial lagoons of Peñalara are surrounded by alpine scenery, meadows, and high mountain scrub. Reservoirs like Embalse de La Jarosa and Pirón Reservoir are nestled within extensive pine forests and meadows. The route to Cascada del Purgatorio passes through dense forests of pines and oaks, offering impressive fluvial landscapes.
While not a lake itself, the Cascada del Purgatorio is a prominent and beautiful water feature in Rascafría, formed by the Arroyo del Aguilón. It's a popular hiking destination, especially in spring, and can be combined with visits to nearby areas. You can find more details on waterfall hikes in the region.
While the glacial lagoons of Peñalara and larger reservoirs are popular, smaller glacial lagoons like Laguna Chica and Lagunas de los Claveles in the Peñalara massif offer a more secluded experience, though they may dry up in summer. Hoya Encavera, near Lozoya, features natural pools along the river and is described as a peaceful spot for nature lovers, offering a quiet environment to enjoy clear waters.
The terrain varies significantly. Hikes to the glacial lagoons of Peñalara involve high-mountain, rocky gneiss areas with significant elevation gains. Trails around reservoirs like Espinar Reservoir (Vado de las Cabras) or La Jarosa often traverse pine forests and meadows, offering more moderate and accessible paths. Some routes, like the Descent to Embalse de la Aceña, can have slightly broken terrain in sections.
Visitors frequently highlight the stunning natural beauty, tranquility, and the opportunity to disconnect. The reflections of pine trees and blue skies in the calm waters of reservoirs like Puente Alta Reservoir are often praised. The diverse perspectives gained from walking around reservoirs like La Aceña Reservoir are also a favorite, as is the picturesque setting of Pirón Reservoir amidst pine trees and mountain views.
No, wild swimming is generally not permitted in many of the protected aquatic features, especially reservoirs like Embalse de La Jarosa, where bathing is explicitly prohibited to preserve the environment and water quality. The glacial lagoons of Peñalara are also highly protected, with fenced areas to prevent human access to the water. It's important to respect local regulations and conservation efforts.
While the focus is on natural beauty, some routes near water features pass by historical sites. For instance, the hike to Cascada del Purgatorio offers views of the 18th-century Puente del Perdón and the historic Monasterio del Paular, adding a cultural dimension to your outdoor experience.
