One of the few bridges over the stream. In winter water can get up to the bottom of the start of the bridge, but it's still usable all year.

Good place, next to Casilla de la Retuerta, to make a stop.

With the rains, it can be somewhat complicated to cross (see photos), but there is one of the few bridges in the area that allows you to cross the river.

Another interesting aqueduct from the time of Isabel II intended to supply water to the capital!

This gate gives access to a narrow but not very difficult path that connects the northern area of the Viñuelas castle preserve with Ciudalcampo. It runs between two fences of private reserves that cannot be entered.
