Descent to the Marmota bridge is quite technical, both uphill and downhill.

Stone bridge over the Manzanares River between Colmenar Viejo and Hoyo de Manzanares. Several hiking routes start from this place.

Although tradition attributes it a Roman origin, the bridge was built in the Middle Ages. It takes its name from an old fulling mill upstream, although in the 16th century it also began to be known as the New Bridge. It probably received this name after some remodelling, following a possible flood. A branch of the Cañada Real Segoviana, a livestock route of approximately 500 km, which links the current provinces of Burgos and Badajoz, passes over the Batán bridge.

Route along a very marked path passing through a stream with stones, seeing the Batán and Grajal bridges ending at the Colmenar Viejo train station.

Beautiful environment, although if you go gravel you will surely have to set foot on the ground two or three times to reach it.
