A comfortable route through Lapurdi, a circular route departing from Irun, traveling inland through Urruña and Ascain, returning to the coast via Donibane-Lohitzun and following the coast through Hendaye to the starting point.

The 2700m tunnel is impressive and seems to never end. Advice: Bring clothes at least when passing through this tunnel as it is cool. Otherwise there is automatic lighting.
