A beautiful, lightly traveled road along the Gave d'Issaux. In two parts: one making its way between rock walls with beautiful views of the mountain foothills, and the other in the heart of a forest offering a haven of freshness during hot summer days. Very pleasant.

The trail goes down through lapiaz land towards the Puerta de Larra “Larrako Ateak”, a tricky spot due to the textures of the mountains and the contrasts of colours. On the way there are poles of the variants that go down to the Linza Refuge, Zuriza and other areas of the karst kingdom of Larra. The GR-12 markings continue through the Hoya de la Solana valley and down to the channel that enters the Ukerdi Integral Reserve, a unique space with a special declaration of conservation within the Larra massif due to the values geological and forestry, where there is an important grove of black pine quite scattered over the lapiaz floor, the sinkholes and the labyrinth of closed valleys that make up the highest and most complicated sector of Larra. The trunks of dead trees put striking touches of authenticity in the desolate karst desert. The route reaches the hardest and most technical section of the itinerary, where choosing the right footwear and experience walking on rough terrain is essential.
