Before starting the climb: check the weather forecast and make sure you have the appropriate clothing. The climb can be done in the clouds (fog) towards the end. A fluorescent vest is not an exaggerated luxury. The road is sometimes narrow, the cars drive fast. For the descent, it is best to take a windbreaker and an undershirt with long sleeves. Light gloves prevent your hands from getting numb, which makes braking more difficult. At the top near the inn at the border crossing, horses walk freely on the road. During the descent along the Basque side you can meet a real pig (180+ kg) in the middle of the road.
