A gradient that will not leave any cyclist indifferent, especially cycle tourists, more bearable from Contreras to Silos, from Silos more gradient and the last 200 meters before reaching the top in both directions is a wall, but it is worth it, fountain at the top.

The railway crossed this port through a tunnel. When making the greenway, the original route was not recovered, so the arrival and departure of the port are two very steep slopes. Most panniers make them by pushing the bike.

The fictional cemetery “Sad Hill Cemetery” was artificially created for the filming of “Two Glorious Scoundrels”. The scene of the big showdown is iconic, in which the three opponents face each other between the graves of an old cemetery in a haunting finale. The cemetery was exposed to increasing decay. A group of courageous residents polished up the cemetery in 2016 in time for the 50th anniversary of the cult western.
