Famous Cycling Climbs
French Pyrenees
Col du Tourmalet
The Giant of the Pyrenees
Col du Tourmalet is the highest paved pass in the French Pyrenees, a climb that has tormented and thrilled cyclists for over a century. As one of the most frequently featured climbs in the Tour de France, it is a true icon of the sport—where legends are made, and suffering is inevitable. With its relentless gradients, dramatic switchbacks, and high-altitude exposure, this is a must-ride challenge for any serious cyclist.
A Ride Through History & Brutal Slopes
Ascending Col du Tourmalet is a journey through cycling history, tracing the tyre tracks of the sport’s greatest riders. The climb has been part of the Tour de France over 80 times, first appearing in 1910 when race director Henri Desgrange dared the peloton to tackle its ruthless gradients and unpredictable mountain weather.
Col du Tourmalet is not just a climb—it’s an experience, a battle, and a rite of passage for any cyclist. Conquer it, and you join the ranks of legends.
West Approach – From Luz-Saint-Sauveur (17.1 km, 7.3%)
The western ascent from Luz-Saint-Sauveur is the most famous route, winding through forested switchbacks before emerging into a vast, exposed landscape of rugged rock faces and alpine pastures. The final 8 km are brutal, consistently above 9%, with little respite before the last torturous kilometre.
East Approach – From Sainte-Marie-de-Campan (18.6 km, 7.5%)
Starting in Sainte-Marie-de-Campan, this route is slightly longer but equally demanding. The first 9 km are deceptively gentle, before hitting the infamous La Mongie ski station, where the gradient kicks up to 10% in sections, testing even the strongest riders.
The final push to the 2,115m summit is an all-out battle against gravity, where thin air, tired legs, and the iconic Tourmalet statue at the top signal victory.

Port de Balès
The Hidden Gem of the Pyrenees
Tucked away in the heart of the French Pyrenees, Port de Balès is a climb that demands respect, rewards persistence, and captivates with its stunning scenery. Though less famous than Tourmalet or Alpe d’Huez, this remote, high-altitude ascent has quickly earned a reputation as one of the most challenging and beautiful climbs in France. Introduced to the Tour de France in 2007, its unpredictable gradients, narrow winding roads, and breathtaking views make it a true test of endurance and grit.
A Ride Through Seclusion & Suffering
Port de Balès isn’t just a climb—it’s a journey through the untamed beauty of the Pyrenees. With its steep gradients, unpredictable nature, and stunning views, it remains one of France’s hidden cycling treasures. Conquer it, and you’ll understand why those who ride it never forget it.
Unlike the crowd-filled switchbacks of Alpe d’Huez or the legendary battles fought on Col du Tourmalet, Port de Balès offers something different—solitude and wild beauty. The climb is often empty, with little more than the sound of your own breath and the occasional cowbell ringing in the distance.
The Ascent – From Mauléon-Barousse (19.2 km, 6.2%)
The climb begins in Mauléon-Barousse, a small mountain village that marks the gateway to this gruelling ascent. The first 6 km are deceptively gentle, luring riders into a false sense of comfort before the real challenge begins.
At km 7, the gradient ramps up, hovering between 8-10% with no consistent rhythm. The climb weaves through dense forest, creating an enclosed, almost eerie atmosphere that forces riders to focus purely on their effort.
With 5 km to go, the trees disappear, revealing a stunning high-mountain landscape. Here, the wind can be brutal, adding an extra layer of difficulty. The final hairpins are relentless, and just when you think you’re done, the road kicks up one last time before revealing the breathtaking summit at 1,755m.

Hautacam
The Brutal Pyrenean Test
Hautacam is one of the toughest and most unpredictable climbs in the Pyrenees, a mountain that has delivered thrilling Tour de France battles and shattered the dreams of even the strongest riders. With sudden gradient changes, no consistent rhythm, and leg-burning steep ramps, this climb is a true test of endurance and mental toughness. Unlike the iconic switchbacks of Alpe d’Huez, Hautacam offers no respite, making it one of the hardest summit finishes in the Tour de France.
A Ride Through Relentless Slopes & Tour de France Glory
Hautacam doesn’t ease you in—it throws you straight into the deep end. The climb begins in Argelès-Gazost, a charming Pyrenean town, but as soon as you leave, the road kicks up sharply and never truly lets up.
The Ascent – From Argelès-Gazost (13.6 km, 7.8%)
The first 2 km start at a brutal 9-10% gradient, immediately putting pressure on the legs. Unlike climbs with predictable switchbacks, Hautacam has an unpredictable rhythm—one minute you’re grinding up a steep ramp, the next, you get a slight easing before another punishing section.
At km 5, the road briefly flattens before spiking back up to 11-13%—a pattern that continues all the way to the top. This inconsistency makes it difficult to find a steady cadence, forcing riders to constantly adjust their effort.
The final 4 km are the toughest, with prolonged ramps over 10% and sections hitting 15%. With no clear sight of the summit, it’s a battle of willpower to keep pushing forward. The last few turns, exposed to the wind, only add to the challenge before reaching the 1,520m summit—where you’ll find yourself gasping for air but exhilarated by the achievement.
Hautacam isn’t just a climb—it’s a war of attrition. With its relentless gradients, unpredictable ramps, and historic Tour de France moments, it remains one of the ultimate cycling challenges in the Pyrenees. Conquer it, and you’ll have taken on one of the hardest summit finishes in professional cycling

What sets Portet apart is its sheer altitude—at 2,215m, it is the highest paved road in the Pyrenees, making it an oxygen-draining and muscle-burning challenge.
The Ascent – From Saint-Lary-Soulan (16 km, 8.7%)
The climb begins in the bustling town of Saint-Lary-Soulan, where the gradient immediately kicks up to around 8%. Riders must settle into a steady rhythm early, as the road offers very few moments of relief.
By km 4, you’ll hit the first major switchbacks, where the gradients fluctuate between 9-11%. The road remains narrow and winding, adding to the challenge, but the stunning mountain vistas make it all worthwhile.
At km 10, you leave behind the tree-covered sections and enter a barren, high-mountain landscape. This is where the real suffering begins—with no shelter from the elements, you’re fully exposed to wind, altitude, and the sun.
The final 4 km are an absolute grind, with long, straight sections above 10% that test both body and mind. The road is freshly paved but narrow, creating an almost Tourmalet-like experience as you push towards the summit.
Finally, after what feels like an eternity, the Col de Portet summit at 2,215m comes into view—rewarding you with jaw-dropping 360° views of the Pyrenees and a true sense of achievement.

The longer, more dramatic approach from Saint-Michel-de-Maurienne begins with the ascent of Col du Télégraphe (11.8 km, 7.3%), a challenging climb on its own. After descending into Valloire, the true test of the Galibier begins—a 24 km grind with over 1,200m of elevation gain.
The early gradients are deceptive, but as the climb unfolds, the switchbacks become tighter, the road narrows, and the landscape transforms into a barren, rocky wilderness. As you rise above 2,000m, every breath feels heavier, and the final 8 km bring sustained gradients of 8-10% with no shelter from the elements.
Finally, at the summit, you’re greeted by the famous monument to Henri Desgrange, the founder of the Tour de France. The breathtaking descent that follows is a well-earned reward—fast, sweeping, and utterly unforgettable.
Col du Galibier is more than just a climb—it’s a rite of passage for every serious cyclist. Whether you’re chasing a personal best, riding in the wheel tracks of Tour de France legends, or simply taking in the grandeur of the French Alps, this is a climb that stays with you long after your legs have recovered.

Col de la Madeleine
A Hidden Gem of the French Alps
Tucked away in the Savoie region of the French Alps, Col de la Madeleine is a true test of endurance and climbing prowess. Though it may not have the same headline status as Alpe d’Huez or Mont Ventoux, it is a Tour de France staple, having appeared in the race more than 25 times since its debut in 1969. With stunning switchbacks, steep gradients, and panoramic alpine views, this climb is an essential ride for any cyclist looking to take on one of the sport’s greatest challenges.
A Ride Through Alpine Majesty & Relentless Slopes
Col de la Madeleine is a climb of two personalities, depending on whether you tackle it from the southern approach via La Chambre or the northern route from Feissons-sur-Isère. Both routes are long and unforgiving, rewarding riders with a sense of accomplishment and jaw-dropping views at the summit.
The Classic South Side – From La Chambre (19.2 km, 7.9%)
The southern approach from La Chambre is the steeper and more challenging of the two routes. Starting in the Maurienne Valley, the road wastes no time ramping up to 8-9% gradients in the first few kilometres. There are no real recovery sections, just an unrelenting uphill battle through dense forests and scattered alpine villages.
As the climb progresses, switchbacks begin to open up, revealing spectacular views of the surrounding peaks, including Mont Blanc on a clear day. The final 4 km are the toughest, consistently sitting around 9-10%, testing both legs and lungs as you push towards the 1,993m summit.
The reward? A breathtaking, remote mountain pass, often less crowded than other famous climbs, offering a true sense of achievement at the top.
The Gentler North Side – From Feissons-sur-Isère (25.3 km, 6.2%)
The northern approach is longer but more gradual, making it slightly more forgiving than the brutal south side. The first section is a deceptive false flat, gently winding through green pastures before the real climbing begins. The middle portion of the ascent offers a rhythmic climb, with sections hovering around 6-7%—a steady effort, but one that still demands endurance.
As you near the summit, the landscape transforms into classic high-Alpine terrain, with rugged peaks and lush meadows stretching in every direction. Though less steep than the La Chambre approach, the final kilometres are still a grind, with gradients touching 9-10% before reaching the summit sign at 1,993m.
Col de la Madeleine is not just another mountain pass—it’s a true test of climbing ability, a high-altitude battleground, and a hidden treasure in the French Alps. Whether you’re chasing a personal best, following in the pedal strokes of Tour de France legends, or simply looking for a ride that will push you to the limit, this climb will leave a lasting impression.

Col de la Croix de Fer
A Tour de France Classic in the High Alps
Nestled deep in the French Alps, Col de la Croix de Fer (Pass of the Iron Cross) is one of cycling’s most rewarding and picturesque climbs. Frequently featured in the Tour de France, this legendary ascent challenges riders with long, grueling gradients, breathtaking alpine scenery, and an unforgettable summit finish. The climb’s unpredictable rhythm—fluctuating between steep ramps, false flats, and rolling gradients—makes it a true test of endurance and strategy.
With its rugged beauty and rich cycling history, the Col de la Croix de Fer is a must-ride for any cyclist looking to experience one of the most authentic mountain passes in France.
A Ride Through Alpine Majesty & Brutal Gradients
The Col de la Croix de Fer can be climbed from multiple directions, but the two most famous approaches are from Saint-Jean-de-Maurienne (north side) and Rochetaillée (south side). Both routes offer their own unique challenges, but they share incredible alpine landscapes, unpredictable gradients, and a finish that rewards the effort with one of the most scenic summits in the Alps.
The North Side – From Saint-Jean-de-Maurienne (29 km, 5.2%)
The longest and most deceptive approach, this side of the Col de la Croix de Fer begins with a gentle start, lulling riders into a false sense of security. The first 10 km average just 3-4%, allowing for a steady rhythm and even moments to relax.
But just as you begin to settle in, the road pitches sharply upwards, revealing the true nature of the climb. The gradients fluctuate dramatically, with sections hitting 8-9%, only to ease off again before another punishing ramp.
At Pontamafrey, the climb intersects with the road to Col du Glandon, and this is where the challenge truly begins. The final 8 km are consistently steep, with gradients hovering between 8-10%, forcing riders to dig deep. The last few switchbacks wind through barren, high-alpine landscapes, with towering peaks in every direction.
Finally, after a gruelling 29 km, you reach the iconic summit at 2,067m, where a wrought-iron cross marks the historic peak of the climb.
The South Side – From Rochetaillée (22.7 km, 6.9%)
This approach is shorter but more intense, making it the favored route for Tour de France attacks. From Rochetaillée, the climb begins almost immediately, testing the legs from the start.
The first 6 km feature sustained gradients of 7-8%, winding through forested slopes before opening into classic Alpine meadows. Riders pass through Le Rivier d’Allemont, where the gradient briefly eases, offering a short chance to recover before the final push.
The last 6 km of the climb are some of the toughest, with sections reaching 10-11%. The switchbacks feel endless, and the high-altitude exposure makes for an even greater challenge. As you crest the final bends, the col’s famous iron cross comes into view—a fitting reward for an extraordinary ascent.
Col de la Croix de Fer is more than just a climb—it’s an experience. With its legendary Tour de France history, ever-changing gradients, and breathtaking landscapes, it remains one of the most rewarding climbs in cycling. Whether you’re chasing a personal best or just aiming to reach the summit, the Iron Cross awaits.

Col d’Izoard
The Iconic Ascent Through the Casse Déserte
Rising high in the French Alps, Col d’Izoard is one of the most legendary and visually striking climbs in cycling. With its rugged, lunar-like landscapes, rich Tour de France history, and unrelenting gradients, this climb is a true bucket-list challenge for cyclists worldwide. First introduced to the Tour de France in 1922, Izoard has become a defining moment in many editions of the race, where cycling greats such as Fausto Coppi and Louison Bobet etched their names into history.
Whether you’re tackling its winding forested roads from Guillestre or the steeper, more exposed route from Briançon, Col d’Izoard is more than a climb—it’s a journey through the heart of cycling folklore.
A Ride Through History & Stunning Alpine Scenery
The Col d’Izoard is one of the most unique climbs in cycling, not just for its difficulty, but for the sheer drama of its landscapes. The summit at 2,360m makes it one of the highest passes regularly used in the Tour de France, and its final kilometers—through the Casse Déserte—are unlike anything else in the Alps.
There are two primary ascents, both of which offer challenging gradients and breathtaking scenery.
The Northern Approach – From Briançon (14.1 km, 7.3%)
The shorter but steeper northern ascent starts in Briançon, a town famous for its fortified Old Town and strategic location. The first few kilometers offer a gradual but deceptive start, with gradients around 5-6%.
As you leave the valley behind, the climb kicks up, winding through dense forests with sections hitting 9-10%. The switchbacks are relentless, demanding a steady pace. About halfway up, you pass the Refuge Napoléon, a historic mountain refuge built during Napoleon III’s reign, marking the transition to the more exposed, high-altitude terrain.
The final stretch through the Casse Déserte is the highlight of the ride. The landscape transforms into an otherworldly, barren expanse, with sharp rock formations and a desolate beauty unlike anywhere else in the Alps. The monuments to Fausto Coppi and Louison Bobet, two of cycling’s greatest climbers, stand as a reminder of the Tour’s history on this mythical mountain.
After navigating the final switchbacks, you reach the summit at 2,360m, where the crisp mountain air and stunning views provide an unforgettable reward.
The Southern Approach – From Guillestre (19 km, 6.9%)
The southern ascent from Guillestre is longer and more varied, making it a test of endurance and strategy. The first 8 km are deceptively gentle, allowing riders to find a rhythm as they ride through lush Alpine meadows and past rushing mountain streams.
Once past Château Queyras, the climb intensifies, with long, exposed sections that demand focus. The road snakes through towering rock faces, offering stunning views of the surrounding peaks.
The final 7 km are the most brutal, with the road narrowing and the gradients stiffening as you enter the Casse Déserte. Here, the climb feels truly remote, with jagged cliffs and an eerie silence that makes the final push to the summit even more dramatic.
Once you crest the Col d’Izoard, the sense of achievement is immense—you’ve conquered one of the most historic and breathtaking climbs in cycling.
Col d’Izoard isn’t just a climb—it’s an experience. The combination of steep gradients, Tour de France history, and the otherworldly beauty of the Casse Déserte make this a truly legendary ascent. Whether you’re following in the footsteps of cycling greats or simply taking in the views, the moment you reach the summit will stay with you forever.

Grand Colombier
The Beast of the Jura Mountains
The Grand Colombier may not have the same fame as Alpe d’Huez or Mont Ventoux, but make no mistake, it’s one of the most punishing and majestic climbs in France. Nestled in the Jura Mountains, this ascent has become a modern icon of the Tour de France, thanks to its savage gradients, stunning switchbacks, and breathtaking views over the Rhône Valley and Lake Bourget.
A Climb That Commands Respect
Climbing the Grand Colombier from Culoz is a relentless test. The road wastes no time, throwing you into double-digit gradients early on as you snake past forested hairpins carved into the limestone cliffs. It’s not just long, it’s unpredictable. The climb kicks, flattens slightly, then kicks again, daring you to find any rhythm.
After the initial stretch, the road hugs the exposed cliff face in a dramatic series of hairpins, revealing views that are as rewarding as they are distracting. Below, the Rhône winds its way through the valley, while above, the road clings to the mountain like a ribbon. On clear days, the Alps even make a cameo in the distance.
What makes Grand Colombier unique is its variety of ascents; there are four routes to the summit, each with its own flavour of pain, but the Culoz approach is undoubtedly the most iconic and visually spectacular. Add in Tour de France banners flapping in the wind, painted names on the road, and you’ll feel like you’re part of the peloton.
The Grand Colombier doesn’t play games. It’s challenging, raw, and demanding, making it one of France’s greatest climbs. This is the one if you’re after a ride that tests your legs, challenges your pacing, and rewards your courage with panoramic drama. Cresting the summit isn’t just a victory, it’s a rite of passage.
