The Hervidero Waterfall is a double waterfall on the Guadalix River, nestled in a rocky canyon and surrounded by riverside vegetation. It can be reached via a flat and easy 7 km (round trip) route starting from San Agustín del Guadalix, ideal for family hikes.

Mountain refuge near the Laguna Grande de Peñalara, with spectacular views of the surrounding area. It's worth returning from the lagoon to the reserves, passing through the refuge—the views won't disappoint.

This refuge is located in one of the most beautiful meadows in the Guadarrama mountain range, on the north side of Peñalara. It is important to maintain it and keep it in good condition.

Tired from the climb, you sit down sheltered from the wind and eat a snack. If it's not windy or cold, look toward Peñalara and make out the landscapes and lagoons. Look toward the Bola del Mundo and admire the scenery. Look toward La Cuerda Larga and explore its grandeur.
