Right where the antennas are, and very close to the San Lorenzo hermitage.

This is a special and magical forest. It is thick and green and feels very different from the surrounding peaks. It can be a bit messy when wet and even a bit difficult, but that's part of the fun.

This trail just below the Belabieta peak is very pretty. It has open fields and beautiful views. So if you don't make it to the top, you still have a good experience.

It is a steep and somewhat difficult climb in the direction of Belabieta. The views are nice, but you may have to push your bike to enjoy them. On the other hand, it is a fast and fun descent.
