Burgui is the starting point in the lower or southern part of the Roncal Valley, which ends in Belagua, at the foot of the Piedra de San Martín. It is a very pretty and peaceful village, with all kinds of services for staying for a few days and using it as a starting point for the various cycling excursions in the area. It is also highly recommended to reach Burgui via the road from Salvatierra de Esca, following the course of the Esca River through the Esca Gorge.

Access from the pass is simple, along a good path through beech forest, the Paso del Oso, a natural window, is not dangerous in itself, unless you lean too far out; there are people who stand at the top for photos.

An incredible work of art of nature! This impressive canyon formed by the Salazar River is a true natural wonder that you have to visit if you are in the area. From the viewpoint at 630 masl you will have amazing views of the entire reserve.
