Tips from the Community
It is a MUST of the Pyrenees, without a doubt, that should be included in any route that crosses the Pyrenees from side to side. Any 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 quiet 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.

The highest peak in the Catalan Pyrenees is well worth the visit, although you have to earn it as it is a long route with considerable elevation gain to overcome.

Great panoramic view of France and Spain and the mega beautiful mountain scenery. I am very happy that the weather held up during our ascent. It was really mega beautiful up there. However, the ascent and descent are not for the inexperienced.

I liked the climb from the north side (from Massat), very scenic and alpine landscapes towards the end at the étang de Lers

A magnificent spot with the road winding under the rock, running alongside a partially underground stream. It's both breathtaking and peaceful. Plus, there's a starting point for a short walk; I did the beginning and it was lovely: I'd love to come back and do a longer section!

Fantastic panoramic views all around; this summit is well worth it, as you can see from my two panorama photos. Ascent from Estany de Sotllo via the pass. I took the partly exposed scrambling/climbing ridge via Pic Verdaguer. Beautiful scrambling; you just have to be careful to stay on the right track. Descent around the summit, then back to the same pass and down past the same beautiful mountain lakes, and via the Valferrera Hut into the valley. The length and roughness of this route surprised me. Luckily, I didn't start my ascent from the hut. The section along the mountainside, especially above the hut, was quite challenging. There are frequent short climbs over rocky outcrops, and at one point, I found myself on a side path below the main trail, which then ended in the undergrowth. After a short climb, everything was fine again.

The climb is steep, but manageable. The view from up there, stretching far into France, is definitely worth it!

Half of those present aren't following the rules! At the start of the climb, a sign clearly states that swimwear should be worn out of consideration (especially for children). Instead, a Frenchman presents himself completely naked. Some French women enjoy exposing their breasts. Everyone present is smugly sprawling, lying head-to-toe in the water without a single gesture of consideration for newly arrived visitors. A little further upstream from the spring, we encounter the third disappointment: Down in the village, several signs indicate a camping ban. A few meters above the spring, we found a camping tent in the forest (keyword: wild camping) and a prepared campfire site (as if there weren't enough forest fires in France by 2025). The behavior of some of the people is unacceptable.
