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.

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%.

The Col d'Ibardin is very close to the Franco-Spanish border. It is an ideal place to eat and fill up on water.
