Highlight • Summit

Ventana del Relux

Highlight • Natural Monument

A bit complicated to follow as it is not very clear. Watch out for cows.

- Garmin data: 3:40h total time, 339m total unevenness. Video: relive.cc/view/vevWB4Dpoyq. This video only reaches the top of El Mazo, because my battery ran out just when I got there. It is not very important, because what was left was almost all repeated and simple.
- NOTE: very interesting and "mountain" route, but not without risks, due to the difficulty …
