This time the route goes south, looking for the Ollo Valley and the mythical ascent to San Miguel de Aralar from Uharte Arakil. But before reaching these areas the route has other attractions such as the passage through Imotz before reaching Irurtzun. Here we start the Ollo Valley loop.
If what you are looking for is to know the ascent of San Miguel reducing mileage, thanks to the design of the route you can continue the same towards Uharte Arakil eliminating this loop. In the Ollo Valley you will be able to climb Azanza with its 8.5 km at 5% and enjoy the views of the valley from its summit.
Little can be added about the ascent to San Miguel de Aralar. Its 9 km at 7.5% average but with sustained ramps of 9% give us an idea of its hardness, but yes, with a good reward in the form of views.
