Cycling the Col du Soulor: Scenic Pyrenees Climb Guide

The Col du Soulor climb might be one of the best Pyrenees cycling routes in these fabled mountains. Our favourite Col du Soulor route winds itself up from Argelès Gazost along 30km of breathtaking road, climbing just under 1,500m of vertical ascent with a steady Col du Soulor gradient averaging 4.7%

Cycling the Col du Soulor: Overview

You kick things off with a punchy ascent, the kind that gets your legs working and your spirit soaring. That early effort levels off onto a peaceful plateau, giving you a chance to breathe deep and take in the expansive mountain views. But the respite doesn’t last long. Just past the charming village of Arrens, the road ramps up again—eight kilometres of relentless climbing take you straight to the top of the Col du Soulor, a regular feature on the Tour de France.

Location of the Col du Soulor

The Col du Soulor is a climb in the heart of the Pyrenees. With famous peaks all around, the Soulor takes its place as a Pyrenean great. The closest large town is Lourdes, 30km away and served by a very small airport. To climb the Col du Soulor, unless you can fly to Lourdes, most people will fly to Toulouse, a couple of hours away by car.

Connection to Col d’Aubisque

From the summit of the Soulor, things get spectacular. The road dips briefly before sweeping back uphill, hugging the sheer rock face above the dramatic Cirque du Litor. This stretch to the Col d’Aubisque is pure cycling theatre—a narrow ribbon of tarmac suspended above a deep limestone gorge, with nature all around and nothing but adventure ahead.

At the top, 1,711 metres above sea level, you’re greeted by panoramic views, the iconic trio of bike sculptures, and an auberge where you can refuel and revel in what you’ve just achieved. Two short, moody tunnels add a twist to the final section, and don’t be surprised to share the road with nonchalant cows, sheep, goats or even horses—this is their turf too.

Col du Soulor Climb Profile and Route Options

Our favourite way to take on cycling the Col du Soulor is to ride the loop that also takes in the Col d'Aubisque.

Our ride up the Col du Soulor route begins in Argelès-Gazost, and what lies ahead is a glorious 12-mile climb with 1,019 metres of elevation gain and an average Col du Soulor gradient of 5.2%. It’s a steady ascent that’ll test your legs but reward your spirit at every turn.

Not far into the climb, you’ll glide through the peaceful village of Arras-en-Lavedan. It’s quaint, beautiful, and quietly tucked into the mountains—though probably a bit early to stop unless you’re after a photo. Further on, you’ll reach Estaing, sitting at 320 metres, where a café stop could be just the thing if you’re taking your time and soaking up the day. The road does start to bite after this, with sections pushing over 10%, but keep your pace in check and you’ll have no trouble enjoying the rhythm of the ride.

This is one of those climbs that stays with you. The road is narrow—narrow enough that two cars would struggle to pass—but that only adds to its charm. It's wonderfully quiet, and even in peak season you’ll have the mountain mostly to yourself. As you climb, the road opens up to stunning valley views, with snow-capped peaks waiting to greet you in the distance.

Before the final push, make sure to stop in Arrens-Marsous. It’s your last real chance to grab supplies, top up your bottles, or treat yourself to a well-earned bite. If you're feeling the effort, this is the perfect place to recharge before the road winds higher into the mountains and on towards the unforgettable Col du Soulor to Col d’Aubisque stretch.

Things to Do Around Argelès-Gazost

If you wish to explore nearby towns, Argelès-Gazost is a great place to enjoy the stunning mountains, hike, picnic by fresh running streams or explore the flora and fauna. Many people also visit Lourdes which was made famous in the 19th century due to Marian apparitions and thereafter became an important site of pilgrimage.

If you are a train enthusiast or just want to put your feet up and take in the views, Le Petit train d’Artouste in nearby Laruns is the highest train in Europe. The railway was built in the 1920’s and early 1930’s as part of the engineering work to provide access to the construction of hydro-electric power stations in the region. The train departs in from of the famous Pic du Midi d’Ossau and you can sit back and enjoy a ride in the beautiful Pyrénées.

Tips for Cycling the Col du Soulor

Tackling the Col du Soulor is all about smart planning and steady pacing. With gradients averaging around 4.7–5.2%, it’s tempting to power through early, but finding a rhythm is key, especially as the climb kicks up in the final stretch from Arrens. Make sure you know your route too; whether you're coming from Argelès-Gazost or linking it to the Col d’Aubisque, each approach offers its own challenges and rewards. If you're heading through the dramatic Cirque du Litor, don't forget to bring lights, two short, dark tunnels can catch you off guard, especially in poor weather. And while there’s an auberge at the summit for a post-ride refuel, be sure to carry enough food and water with you to stay energised throughout the climb.

The Stats

There are three routes to the summit of Col du Soulor. The ‘easiest’ option is from the Col d’Aubisque but the views along the way are magnificent.

Many will recognise the road between Soulor and Aubisque from the helicopter photographs that are often taken of this route. All three options are relatively quiet but the second route from Ferrieres is even quieter than the others. You are more likely to encounter traffic from animals than from cars and motorbikes! The third route and our favourite, is through the narrow roads from Argeles -Gazost. This is where most riders choose to start from. Ride this on our Pyrenees Cycling Holiday.

The first 4km of the route is challenging, you will find yourself on a busy road to the village of Arras-en-Lavedan. The gradient then decreases and there is a flat section to rest your legs as you head to Arrens, which is 7.5km from the summit. After Arrens the gradient ramps up with 7km at an average of 8.3% and a maximum of an eye watering 18%. Keep your eyes peeled not only on the road, but for the local wildlife. As this is a preserved nature area, you are likely to see an abundance of fauna and flora, from roaming sheep to migratory birds.
