It is a good area for a quiet route without rushing... except for some sections with a lot of water where you have to walk.

In the Middle Ages, the inhabitants of Bustarviejo had to pay a “toll” of half a bushel to use this pass to carry grain to be ground at the water mills in the Lozoya Valley. Hence the name of this pass. From the pass we can see the Carpetanos Mountains of Somosierra, part of the Lozoya Valley and the entire Sierra Norte of Madrid.

Of great beauty and easy to access (be careful, there are some winding stairs) they are one of these little-known corners of Madrid. In the bed of the Guadalix River and almost at the mouth of its spectacular canyon, the waterfall depends on the opening of the reservoir, upstream, which guarantees water flow practically all year round.
