Already pretty much at the end/beginning of the railway line, here it is even asphalted, before/later not anymore, but always easy to ride.

Beautiful viewpoint with benches and a water source.

If necessary, this is a good opportunity to carry out minor repairs on your bike and refill your water supplies. A short rest at the benches and tables is also a good option.

The railway hasn't run through this tunnel for a long time, but the "Vía Verde de los Montes de Hierro" railway trail runs through here. Very beautiful!
