Best for the most visited summit of the Tour de France

- Length of climb: 19km
- Average gradient: 7.1%
- Elevation gain: 1,323m

View from the summit having cycled Col du Tourmalet, French Pyrenees
Notes
No other climb has featured in the Tour de France as many times as the Col du Tourmalet! The highest peak in the Pyrenees has some sustained steep sections that make it a particularly tough climb.
For those that reach the summit, the impressive iron Geant au Col du Tourmalet statue awaits. Some believe the statue pays homage to Octave Lapize, the first ever Tour de France racer to summit the Tourmalet in 1910.
Octave famously shouted ‘You are assassins’ at the race organisers, a testament to the trials racers face on the Tourmalet’s tough slopes. This is just one of many legendary Tour de France moments to take place on the Col du Tourmalet.
Tips
The upper part of the Col du Tourmalet can be tough in hot weather, as the rocks block the wind and amplify the sun’s heat. Check the summit webcam and plan accordingly.

2. Col d’Aspin (from Arreau)
Best for a Pyrenean climb that provides a more gentle ascent than the Tourmalet
Key statistics
- No. of Tour de France visits: 76
- Length of climb: 11.9km
- Average gradient: 6.5%
- Elevation gain: 794m

Watch out for cattle on the Col d’Aspin!
Notes
Looking for a warm up ride before tackling the Tourmalet? The Col d’Aspin is a good option.
Gentler gradients combine with Pyrenean mountain landscapes to provide a rewarding and satisfying climb. The Tourmalet’s younger brother is often combined on the Tour de France routes, meaning it has some serious race pedigree that can’t be overlooked.
Tips
Watch out for cattle and livestock on the road; they’re quite likely to walk out in front of you! The cows can be large and many have horns. Take care when passing and don’t do anything that may provoke them.
The final few kilometres to the summit average around 8% gradient. Keep some gas in the tank to tackle this tough last stretch.

3. Col d’ Aubisque (from Argelès-Gazost)
Best for one of the most dramatic mountain roads in France
Key statistics
- No. of Tour de France visits: 74
- Length of climb: 29km
- Average gradient: 4.2%
- Elevation gain: 1,415m

The scenic Cirque du Litour road
Notes
Few photos do this climb justice! The scenic Cirque du Litour road up to the summit has been cut out of the mountain and sits above a deep, green ravine. It’s a dramatic experience to ride it, but it’s not for the faint-hearted (see tips below).
The summit itself is also spectacular, with a panoramic view of the Pyrenean mountains. There are also some art installations to admire, including three colourful bikes and a statue of Lucien Buysse, the winner of the 1926 Tour. This bust immortalises his legendary achievement of what is considered the hardest ever stage of the race.
Tips
The Soulor-Aubisque road is not suitable for those afraid of heights or looking to avoid risks. Rocks (and even animals) can fall from the hillside, and the low wall offers little protection if you need to steer away from danger. Keep this in mind when deciding your speed, especially on the way down.
The Aubisque road has two tunnels with rough surfaces. Bring lights, remove your sunglasses, and watch out for livestock.

Tour de France Alps climbs
4. Col du Galibier (from Col de Lautaret)
Best for spectacular landscapes that will blow you away
Key statistics
- No. of Tour de France visits: 64
- Length of climb: 8.5km
- Average gradient: 6.6%
- Elevation gain: 563m

Summit of the Col du Galibier
Notes
It’s little wonder the Col du Galibier has become such a classic of the Tour de France. The climb boasts some of the most mind-blowing, stunning scenery we’ve ever encountered from the saddle!
Each hairpin offers new views over quiet valleys, glaciers and jagged Alpine ranges.
Since its first inclusion in 1911, the Galibier has seen many cycling legends take up the challenge. Most notably this includes Marco Pantani in 1998. In 2011 it was also featured twice to celebrate the 100th anniversary of its first inclusion.
Tips
Take care on the descent! The hairpins are tight and steep. Tragically in 1935 the Spanish cyclist Francesco Cepeda crashed on the descent from Galibier to Lautaret and later died from the head injuries he sustained.

5. Alpe D’Huez
Best for conquering cycling’s most famous climb
Key statistics
- No. of Tour de France visits: 32
- Length of climb: 14km
- Average gradient: 8%
- Elevation gain: 1,120m

The views cycling up Alpe D’Huez are spectacular
Notes
The 21 bends that wind up the Alpe d’Huez climb to the summit are what make it so famous. This must-do climb is synonymously linked with the Tour de France’s rich cycling heritage; each hairpin has been named after former stage winners of the race.
Completing it for yourself cannot fail to give you a new appreciation of what it takes to become a Tour de France champion! It really is one of the best Tour de France climbs you can conquer.
Fun fact: to date, Marco Pantani holds the fastest recorded ascent of Alp d’Huez, with a time of 37 minutes and 35 seconds.
Tips
The climb’s tough gradient should not be underestimated. The first six bends in particular are the toughest, with average gradients of around 11%. Take your time to avoid burning out before you get to the top.
Due to its popularity, the Alpe d’Huez attracts nearly 400 cyclists a day attempting the climb. So, start early if you want to be one of the first on the climb.

6. Col de Braus (from Sospel)
Best for one of France’s most beautiful climbs
Key Statistics
- No. of Tour de France visits: 26
- Length of climb: 11.2km
- Average gradient: 5.7%
- Elevation gain: 642m

Col de Braus with its winding road, at late spring
Notes
The neatly stacked hairpins of the Col de Braus in France’s Côte d’Azur region are certainly photogenic.
This is a relatively short climb compared with others featured in this list, but nonetheless rewarding. It can also be combined it with the Col de Turini (another popular Tour de France climb) for even more of a challenge.
The Col de Braus was a regular on the Tour de France route prior to World War Two. After a long hiatus, the climb was finally featured again in 2024 as part of the historic final stages of the race.
Tips
At the top of Col de Braus, check out the monument to René Vietto, whose ashes were scattered here. He was a top climber in cycling and won his first professional race on the Col de Braus.
In 1934, during the Tour de France, he gave his bike to his injured team captain, sacrificing his own chances. Vietto is considered one of the greatest French riders to never win the Tour.

7. Col de la Madeleine
Best for one of the hardest Tour de France climbs
Key statistics
- No. of Tour de France visits: 25
- Length of climb: 26km
- Average gradient: 6.2%
- Elevation gain: 1,700m

The beautiful Alpine views from the Col de la Madeleine
Notes
First featured in the Tour de France in 1969, the Col de la Madeleine was a relatively late addition to the Tour de France party.
But since then, this spectacular climb has become a regular for the pros to conquer! Memorable moments on the Madeleine include David Millar’s tough and inspirational battle up the mountain in 2010.
Ranked by the race organisers as ‘hors catégorie’ (beyond category) is a testament to the challenge that awaits riders taking it on. Alongside the reward of the climb itself, the views at the summit include the breathtaking snowy peak of Mont Blanc.
Tips
There are multiple routes to choose from! Our ride guide includes five ways to cycle the Col de la Madeleine.
There are handy milestones on both sides of the Col de la Madeleine. These show the distance to the summit, the current height, and the average slope in the following kilometre.
As you reach the summit you’ll notice the road is exposed. There’s little in the way of shelter at the top. Check the weather forecast and webcam before setting off.

8. La Croix de Fer + Col du Glandon (from Bourg d’Oisans)
Best for bagging two climbs in one go
Key statistics
- No. of Tour de France visits: 21
- Length of climb: 42km
- Average gradient: 5%
- Elevation gain: 1,650m

The summit of La Croix de Fer
Notes
Steep, continually changing gradients make the Croix de Fer a challenging climb. The breathtaking backdrop and close proximity (just 2.5 kilometres) to the Col du Glandon make it a big ride that’s not to be missed!
Both the Croix de Fer and Col du Glandon have featured regularly on the Tour de France over the years. There’s plenty to admire on the way up, with the mighty Lac du Grand Maison dam creating a beautiful, vast expanse of turquoise water.
Tips
Don’t let the lower gradient of this climb fool you into thinking Croix de Fer is easy to conquer. This rollercoaster ride can feel fairly relentless and is a big day out on the bike. Pace yourself and enjoy the ride!

9. Mont Ventoux (from Bédoin)
Best for summiting the beast of Provence
Key statistics
- No. of Tour de France visits: 17
- Length of climb: 21km
- Average gradient: 7.4%
- Elevation gain: 1,580m

On the way up the summit of Mont Ventoux is in sight for a tantalisingly long amount of time
Notes
The striking, lunar-like landscapes of Mont Ventoux and the iconic radio tower at the summit are instantly recognisable. They provide a spectacular backdrop for a memorable mountain stage.
By far the most popular route taken by the Tour is from the village of Bédoin, located at the foot of Mont Ventoux. It’s a ride of contrasts, from vibrant lavender fields and vineyards to pine forests and then on to the exposed upper section of the mountain. This challenging climb also features some daunting gradients over a long distance.
It was first featured on the Tour de France route in 1953. Since then, the climb has hosted the pros countless times, including twice in one race in 2021. One of the most notorious Ventoux moments was in 2016 when a serious crash near the summit left Chris Froome’s bike badly broken. With no replacement in sight and crowds of cycling fans blocking his replacement bike, Froome made the bold decision to run up the final kilometre. It would become known as the ‘Mont Ventoux push’.
Tips
Ventoux’s weather is notorious, so be prepared by checking the webcam and weather forecasts before you set off. The summit of Ventoux is also exposed and can be very windy. Cyclists have even been blown off their bikes at the top. Don’t forget to pack some warm layers.
There are multiple ways to climb Mont Ventoux, but the most common starting point (and notably the most regularly featured route on the Tour de France) is from the town of Bédoin.

10. Col de L’Iseran (from Bourg Saint Maurice)
Best for cycling France’s longest climb and highest paved road
Key statistics
- No. of Tour de France visits: 8
- Length of climb: 48km
- Average gradient: 4.3%
- Elevation gain: 2,250m

The snowy summit of the Col de L’Iseran climb
Notes
This huge climb in the French Alps is also Europe’s highest mountain pass. It has rightly earned itself the title ‘King of the Alps’.
The top of the climb sits at 2,770 metres above sea level, the air really does feel thinner here and the views down the valley are absolutely knockout!
Tips
The first 30 kilometres have several long poorly lit tunnels (including one that’s 750 metres long!). Bike lights are therefore essential to tackle this climb safely.
This section is also shared with other traffic and can feel busy up to the ski resort of Val Isère. For the chance to ride on quiet roads, look out for the annual car-free days which stop traffic on the last 17 kilometres of the climb.
