I went first thing in the morning and loved watching the sunrise. The route is manageable, although the descent is a bit long due to the curves and loose stones.

There is a water basin known as Vao de los Lobos (1,127 m). It is a fork in the route. The branch on the right goes directly towards the Hoyo del Tejo, while the one on the left ascends towards the interior of the Ándara Massif.

It is worth getting here to have some beautiful views of the Deva river valley. In the town of Cicera you must take the detour along the north path that leads to the hermitage of Santa Catalina and from there continue a few more meters, highly recommended!

The Urdón Tresviso PR-PNPE 30 route is a route of medium difficulty due to the unevenness to be overcome (more than 800 meters), which runs along paths with sections of loose stone and areas with significant vertical drops without lateral protection. Although, unless you have vertigo, it does not present major objections.
