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

Although you have to make a slight detour, it is worth visiting this bridge and taking a photo on it if you want.

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. 😉

This beautiful city located in the valley of the Oria River is surrounded by small mountains and green meadows. Thus, it offers you the possibility of escaping from the noise of the city in a few minutes. Furthermore, in its historic center is the church of San Martín de Tours, which is undoubtedly worth a visit.

Great tour always along the river and through countless tunnels. Also recommended in hot weather. Bring light if possible.
