Alto de Agiña

Highlight • Mountain Pass

Nice climb up a very quiet road, which runs through a leafy forest, although from time to time the landscape opens up and you can admire the views of the valley and the Endara reservoir.

The slope from Endara is 4.2 kilometers long, with an average gradient of 6.8%. Around kilometer 3 is when the hardest percentages are found, around 8 and 10%.

If you go up from Lesaka the climb is twice as long, but it doesn't really start to get steep until the second kilometer. In any case, it is not a very steep climb until the last kilometer, where there are ramps of up to 11%.

Basakabi Pass (Ezkurra Pass)

Highlight • Mountain Pass

Basakabi is how it is known by almost all Gipuzkoan fans who use the northern slope to access Navarre lands. Basa-Kabi is the name of a hotel-restaurant, currently closed and located at the top. But it is also known as Alto de Ezkurra.

Saldias Climb

Highlight • Climb

A very picturesque section but at the same time demanding when going up from Ituren in the direction of Saldias with a section of slope above 10%. Go easy and enjoy the path that has impressive views over the valley of the Ezkurra river.
