This is the natural pass between the valleys of Chistau and Benasque. As such, it has been used for millennia and proof of this is the megalithic circle next to the track, which even then served to delimit border limits called "mugas".

The best time to visit the mountain peaks around San Juan De Plan is generally during the warmer months, from late spring to early autumn. This period offers more favorable weather conditions for hiking and climbing. However, even in summer, high-altitude peaks can retain snow, and weather can change rapidly, so it's essential to be prepared for varying conditions.
