Porteille des Bésines
Highlight • Mountain Pass
The south face is slightly rougher than the north face without the ascent imposing any great technical difficulties. Be careful though with the weather which can make the passage more challenging.
Do not hesitate to take a break to observe, to the south, the surging peaks that spring from the regional natural park of the Catalan Pyrenees.

Grandiose pass, mid-June with many snowfields for running up and sliding down. Wonderful views all around, to Pic Carlit, Puig Péric and many other peaks, to Lac de Lanoux and Lac d'En Beys (on the mountainside just before the pass) and into the valley towards Hospitalet-près-l'Andorre.

Very good place to practice skating skiing in winter!

The only positive thing about this pass is its relatively moderate gradient. The traffic (until the road to Andorra turns off) is horrific. Hordes of motorcyclists, trucks, cars... If you can, you should avoid this pass.

Although limited to 70 km/h, the tunnel is not passable by bicycle. There's even an electronic toll system.

Col del Pradel is the brother (smaller or bigger) of the Col de Pailhères given its proximity. They are twinned because it is inevitable to climb one without passing the other. Once you move to the area to upload one, you also take the opportunity to upload the other. Col de Pradel is one of the ports that I like. Very narrow gravel road (old fashioned), with tree-lined sections and open sections with good views. A port that seems like you don't know where it takes you, and that is part of its charm. It is a tough port on both sides, although they are very different. I leave you its altimetry prepared by @cyclingcols --> http://www.cyclingcols.com/col/Pradel Col de Pradel does not disappoint any cyclist!
