Seat of Philip II

From this natural observatory the monarch contemplated the development of the works of the Monastery.
Some experts assure that these granite seats, for the king and two companions, are the remains of a thousand-year-old Celtiberian altar. From here you can perceive that the Monastery has the shape of an inverted grill, in homage to San Lorenzo, who was martyred in one of them back in the year 258, since it is located on a small hill from which the Guadarrama Valley and the Sierra de Navacerrada.

Bear Cave

Highlight • Natural Monument

Part of the path that leads to the Chair of Felipe II. It is a cave of rock and vegetation. Don't expect a huge cave, but the hike is worth it.

Stone slab above the Valmayor reservoir

Highlight • Natural Monument

High granite slab that you find when surrounding the Valmayor reservoir when the water level is high. If you do it clockwise you will have to unclimb it, it is advisable to be accompanied to be able to lower the bike safely.
If you do the route counterclockwise it will be more complicated to climb it. The slab is very smooth and has few grip points.

November 26, 2025, Losa de piedra sobre el embalse de Valmayor

On November 26, 2025, the water covered many areas that are normally passable. You had to "climb" several rocks to get around the reservoir. This section was especially tricky when descending, and even more so if you were alone.

They say (I don't know how true this is) that Philip II used to watch the progress of the construction of the colossal monastery from this very spot during his hunting trips, which he was very fond of. Whether true or not, it makes for a beautiful viewpoint, especially in autumn.

The Chair of Philip II is a famous granite viewpoint in San Lorenzo de El Escorial, near Madrid. Legend has it that King Philip II used it to view the construction of the Monastery of El Escorial. However, experts believe it was actually an ancient Celtic altar, possibly used for rituals. Today, it's a popular hiking spot with stunning views of the monastery and its surroundings.

The Bear Cave in San Lorenzo de El Escorial is not a real, deep cave in the geological sense, but rather a peculiar rock formation in the Bosque de la Herrería. It is a natural cavity formed by the arrangement of large granite boulders that create a kind of shelter or "cave." It is located in the Bosque de la Herrería, a protected natural area declared a UNESCO World Heritage Site. It is on a very popular hiking trail, relatively close to the Chair of Philip II and the Fuente de los Hermanitos. Its name comes from the fact that its shape and size might evoke the idea of a bear's den, although no real bear ever lived there. Rather, it is a visual attraction, especially for children. Beyond being a "real" cave, it is a point of interest on the hiking trails in the Bosque de la Herrería.

Today, February 9, after the rains, the reservoir is higher, although you can still cross without climbing the rock, with a little care you won't get wet.

As of January 1, 2025, the water will no longer cover the path that runs under the granite stone and it can be passed through without any complications.
