Flavours of Urdaibai

This circular MTB route from Gernika-Lumo begins along the bidegorri (cycle path) towards Belendiz.

It then climbs to Arrola to continue to Nabarniz and tackle the ascent to Mount Illuntzar. Without reaching the summit, it heads to the Airo beech forest, where it continues along the wide track leading to Ereño.

Continue towards Akorda and cross the holm oak forest, from where you can tackle the climb to the beautiful summit of Atxarre if you take the turn-off to San Pedro de Atxarre at kilometre 35 (optional).

Then descend to Kanala and continue towards Gautegiz-Arteaga, passing the Ozollo tide mill, the Arteaga castle and the Urdaibai Bird Center.

The last section of the route runs along the footbridges of the Urdaibai marshes.
