Top 4 Lakes around Fresnedillas De La Oliva

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.

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.

If the reservoir flow is high, you have to walk and almost climb this rock. Easy, once you've done it.

Along this beautiful stretch you can tour the entire west side of the Cerro Alarcón reservoir, located right between the municipalities of Valdemorillo and Navalagamella. On the other side, easy to see due to the narrowness of the reservoir, you can already see houses from the urbanization.

This small reservoir or dam was originally built after the order of Philip II, who wanted to impound the water from the stream of the same name. Of this first dam, only remains of the wall remain. Later, under the reign of Carlos III, the reservoir was expanded, to be expanded again during the reign of Alfonso XIII by the Abantos Society.

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.

In the first streets of Zarzalejo Estación there is the detour of the Camino de los Molinos that enters the Fuentelámparas pasture, a new environmental wonder in the rural landscapes of the Sierra Oeste. The pasture is dedicated to livestock farms, herds of cows and sheep graze in the grass fields and there are many farmhouses and private farms. The road surface is comfortable until some meadows where a couple of lagoons are created in the rainy season. The pastoral alley passes by some stables and becomes a traditional path between the fences of the livestock farms, with cobblestones and steps that you pass without getting off the bicycle with care and skill. The remains of the old flour mill of Manuel Santos Ventura are hidden in the Portezuela stream, on the left of the road about two hundred meters off the track. And just opposite, on the cliffs of Los Picoruchos, are the ruins of a military fort from the Civil War that dominates the great plain of Fuentelámparas. The trails to visit these two places of historical and ethnographic interest are not cyclable, especially the one that goes up to the old military post, you have to leave the bike hidden near the path and walk a few minutes in both cases. The cattle track leaves the pasture and the route continues along the Camino de San Martín towards Colmenar del Arroyo.
