The climb is hard, but it is worth it. Although we were not lucky enough to see all the scenery that should be seen from that height. The descent is almost harder than the ascent.

Roof climbing training venue. By not having much height, danger is avoided. Just put some mats underneath to cushion falls.

More than a climbing area, it is a learning and training area. They are not high cliffs or difficult areas. There are enough places to choose from and not do the same thing every day.

Once the effort of the climb has passed, and the required photos have been taken, it is advisable to sit in the sun on the blackboards and enjoy the restorative food. But... if it's cold, quickly begin the descent to more protected heights.
