Inland Loop of Urdaibai II

From the landscape of the marshes to the towns and high-rise neighborhoods on the right bank of the Urdaibai estuary. Starting from Kortezubi, this route climbs into the narrow, high valleys between Ereño and Nabarniz, before descending to Belendiz and Arratzu.

Once in Munitibar, we will face the ascent to the Balcón de Bizkaia to continue to Urrutxua and descend to Gernika along the Mendata road. Returning to Kortezubi we can take a detour to the Santimamiñe Cave.
