Le col de Port is the first pass I did in the Pyrenees. You can climb it via a regular road (official road), or an even more pleasant small road. And the view at the summit is well worth the climb!

It is a MUST in the Pyrenees, without a doubt, that should be included in any route that crosses the Pyrenees from side to side. Either of its slopes 2 is spectacular and tough. The views from its summit are wonderful, feeling the wild side of the Pyrenees. Of course, once at the summit of this pass... you have to descend to the Étang de Lers and enjoy a peaceful rest on the shores of the lake. It is a pass that has been part of the Tour de France route on several occasions, although always far from the finish line. The first professional rider to crest it in the lead was the unforgettable Marco Pantani in 1995.
