One of the many alternatives that the Valley of Roncal offers is mountain biking.

There is a fixed, marked circuit more than 50 km long with different branches to meet the preferences of all fans of the sport. As is only natural given the local terrain, the circuits are classified as average-to-very-difficult.

All the circuits are marked and have panels at the start showing the characteristics of the route.

During the year, there are several trials and non-competitive mountain-biking events in the Valley of Roncal, the most important of these being “La Ardibidepikua”, “La cañada de los Roncaleses” and “La Basajaun”.

Leaflets with maps of the routes and information on their characteristics are available from the Isaba Tourist Information Office and the Roncal Nature Interpretation Centre (NB: Leaflet currently sold out).
