The GR10: Everything You Need To Know
The Pyrenees, the mountain chain which forms the border between France and Spain, stretch over 400km from the Atlantic Ocean to the Mediterranean Sea, and at Pico Aneto (entirely within Spain) they reach their highest point at an ice-frosted 3404m. Grande Randonnées, or GR footpaths, are long-distance walking trails throughout Europe. The GR10 is a superb long-distance trail that runs across the entirety of the French side of the Pyrenees from the Atlantic to Mediterranean. Find out more about the GR10, with answers to FAQs and a summary of the 4 sections and 55 stages below!
The GR10 is an extremely well-waymarked route following good mountain paths, with only a few tough stages with boulderfields to cross and occasional scrambling. Towns and villages are frequent so finding accommodation and supplies is rarely a problem.
Initially the GR10 follows ridges over the steep rolling hills of the Basque Country before reaching the impressive limestone peaks at the western end of the High Pyrenees.
After the town of Bagnères-de-Luchon the GR10 passes into the less-frequented Ariège where the route crosses a succession of deep valleys with occasional returns to spectacular Alpine terrain.
As the Mediterranean is approached the Canigou massif dominates the scene and the terrain remains mountainous with the final 1000m peak being only a few miles from the route’s end at Banyuls-sur-Mer.
The highlight of the GR10 for many walkers isn’t the mountains or the fauna (as diverse as this is), but the magnificent wildflower meadows and shimmering lakes in which great peaks are reflected. This is an unforgettable walk through a stunning mountain range.
FAQs and Advice
How long is the GR10?
954km in length with a total climb of 53,000m.
The GR10 is too long for most hikers to do in a single trip and most will break it up into sections and walk it over several years.
How long does the GR10 take to complete?
For a fit walker, it would be possible to complete the entire trek in around 45 days by combining stages.
A goal of 45 days would require some planning ahead to ensure daily distances are realistic and accommodation options fit the intended schedule. It would also require the weather to be reliably on your side and wouldn’t allow for many diversions off the main route, which would be a great pity as these diversions and side trails often lead to the most rewarding experiences and memories. Therefore, we would suggest adding in an extra week at the least.
What is the best time of year to walk the GR10?
The best months to walk the GR10 are mid and late June, July, August and September.
If you are only intending to walk sections of the GR10 in the Basque Country, you may prefer May, June or October when the weather will be cooler. However, trying to complete the entire GR10 in October would be very ambitious and should not be attempted by anyone without experience in snow and winter weather. Also, most of the refuges are unstaffed by October so you’d need to be self-sufficient.
You should be aware that the main holiday season is July and August and that some facilities are only open during those two months. July and August are hot and busy throughout the range and the later into summer you go the more parched the countryside becomes.
Which direction should I walk the GR10 in?
We suggest trekking the GR10 from the Atlantic to the Mediterranean.
This means that you have the prevailing wind/rain on your back and you have time to acclimatise to the heat before reaching the Mediterranean, with the added advantage that in hot weather the steep climbs can often be done in the shade of early morning.
It would still be possible to trek from the Mediterranean to Atlantic.
How difficult is the GR10?
The GR10 is a serious expedition so you should have previous experience of backpacking or long-distance walking before attempting this fantastic route.
On the GR10, especially in the Ariège, you are often traversing very steep slopes where a fall could have fatal consequences. It is not the difficult terrain – there is very little difficult terrain on the GR10 – it is the careless slip on an easy but exposed path that is potentially dangerous. It is strongly recommended that you use two walking poles and learn to use them effectively to prevent a careless slip on a steep traverse.
What should I pack to walk the GR10?
Keep your load as light as possible. If you don’t need it, don’t carry it!
- You will need a sheet sleeping bag or lightweight sleeping bag for use in refuges or some gîtes d’étape. If you are using accommodation you may still want to carry a sleeping bag and camping mat to enable you to bivouac when required.
- Your waterproofs should be able to cope with thunderstorms and heavy rain.
- Shorts are the preferred legwear of most hikers in the high summer.
- A sun hat is strongly recommended and you should use plenty of sun-screen.
- Good quality lightweight boots or sturdy walking they have a good tread.
- Be warned that even in summer it can get cold at night. On some of the higher elevation night stops the temperature can drop to almost zero, even in August, so you’ll want a fleece and a thermal is a good, light-weight, addition.
- If you are camping, you should have, as a minimum, containers capable of carrying three litres of water.
- It is strongly recommended that you use two walking poles. Mini spikes or even full crampons may be needed in early season in a high snow year.
- If you are carrying any electronic devices needing recharging, remember to carry a continental adaptor.
Where should I stay on the GR10 Route?
There is a wide range of accommodation on the GR10.
- Hotels vary greatly in quality and cost but even the cheapest offer a high standard of comfort. An auberge is the equivalent of an English inn.
- Chambres d’hÔtes are private houses offering accommodation similar to the British ‘bed & breakfast’. They are a fantastic way to get a more intimate look at rural French life with dinner (and sometimes breakfast) often being communal affairs hosted by the owners.
- Gîtes d’étape are a network of cheap accommodation aimed primarily at walkers. They often have dormitory accommodation, but many also have smaller rooms. Most, but not all, will offer evening meals, breakfast and picnic lunches. Some will be open for snacks and drinks during the day. Most will have a kitchen for the use of visitors. Don’t get confused by the ‘gîte’ designation; these are mainly chambres d’hÔtes rather than gîtes d’étape.
- Manned refuges are mountain huts (today some are more like full blown hotels!) that offer accommodation, possibly in dormitories. In summer many of them have a drink and meals service, open to both residents and non-residents, and will usually provide packed lunches.
- Unmanned refuges are open year round for the use of mountaineers and walkers. They are equivalent to the Scottish ‘bothy’ and range in quality from purpose-built buildings, which are well maintained by mountaineering clubs, to buildings that are little better than unmaintained cow sheds. Sometimes they are in fact just cow sheds!
- Some campgrounds will have cabins, static caravans or gîte d’étape accommodation.
- If desperate ask at a village bar-restaurant; they will often know locals who are willing to offer accommodation outside the official system.

The Sections - GR10 Route
With a walk of this magnitude, it makes sense to sort it into sections, with lots of walkers completing the GR10 in sections over months, or years. There are good bus and rail links throughout the French Pyrenees so there is plenty of choice when splitting into sections.
For convenience, the Cicerone guide has been divided into four sections, which fit in well with the rail links.
Section 1: Hendaye-Plage to Etsaut (Stages 1–12)
- Distance: 221km
- Ascent: 11,300m
- Time: 68 hours
As the GR10 leaves the border town of Hendaye on the Atlantic coast it follows ridges over the steep, grassy and wooded rolling hills of the Basque Country. After nine stages there is a rapid transition to the steep limestone peaks at the western end of the High Pyrenees.
Section 2: Etsaut to Bagnères-de-Luchon (Stages 13–26)
- Distance: 253km
- Ascent: 14,400m
- Time: 85 hours
This is the most spectacular section of the GR10, passing through the High Pyrenees, which rise to over 3000m, crossing high passes that may be snow-covered well into summer. The fantastic scenery in this section reaches its visual highlights as you pass around the Pic du Midi d’Ossau, Vignemale, Gavarnie and the Néouvielle massif.
Section 3: Bagnères-de-Luchon to Mérens-les-Vals (Stages 27–43)
- Distance: 265km
- Ascent: 17,600m
- Time: 98 hours
In this section, the border between France and Spain (or Andorra) is well north of the watershed and the GR10 passes through the Ariège. These mountains aren’t quite as high as the High Pyrenees, but the route crosses a succession of deep valleys cut out by the huge glaciers that flowed north from the Pyrenees in the last Ice Age, meaning that there is a lot of ascent. The Ariège has never been as popular as the High Pyrenees so there is often a feeling of remoteness as you walk through a land of deep forests and across pastures where a traditional shepherding lifestyle remains strong. This region is also a stronghold for brown bears and other wildlife. Facilities for walkers are harder to find.
Section 4: Mérens-les-Vals to Banyuls-sur-Mer (Stages 44–55)
- Distance: 215km
- Ascent: 9700m
- Time: 64 hours
The first few days of this section are through spectacular Alpine terrain, after which the mountains become gentler. After the dominating Canigou massif is passed, the terrain becomes drier and notably more Mediterranean but remains mountainous, with the final 1000m peak being only a few miles from Banyuls-sur-Mer.
