A bar with a view and good food, a good place to stop. Closed Mondays.

Great route for beginners as has mainly constant and light slopes. Only half a dozen uphills the first 30 km from Pamplona.

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.

That bridge is called "INTUIA-ko zubia" the INTUIA farmhouse is next to it. The misnamed "witches' bridge" is called UNANIBI-ko zubia, right in the Otita park (beginning of the Leitzaran valley). Don't forget to bring lights to cross the numerous tunnels in this valley!! Not to see but to be seen.

A must when you pass through this area. Stopping and having a coffee is almost mandatory. 😉
