The name comes from the stone boundary markers erected in the 18th century to demarcate lands acquired by Charles III for hunting. During the Spanish Civil War, it was a strategic area with a Republican detachment stationed there. It formerly housed the Valcotos ski resort, which no longer exists.

There's a fountain as you reach the top on the right. Follow the cobblestone path.

No water comes out, mind you. Even so, it's a legendary spot in the Navacerrada Pass.

Mandatory stop on the way down to refill water. (Or uphill, but you have little left and you have to suffer until the end)

One of the most beautiful and toughest passes in the mountains. Beautiful climb but little shoulder and a lot of traffic on weekends. There are a lot of bikes so it is not a problem because it is respected, but it is good to know. Be patient, and enjoy the wind, that stretch is tough but the reward is closer.

A small but charming 16th century chapel, with yellow stucco, in the small town of Ortigosa del Monte.

The Church of San Juan Evangelista de La Losa is located on a small hill above the small town. There is a small park surrounded by some of the oldest buildings in the area, including an old cemetery.
