GR10 Section 5: Luchon to Aulus les Bains

Your walk from Luchon to Aulus les Bains

You'll walk 124 kilometres of the GR10 through the French Pyrenees — over seven cols above 1,700 metres, through abandoned zinc mining country, and across the Spanish border ridge at Pic de Bacanère. A serious section, with 8,335 metres of ascent and a thermal village at the end.

Section 5 is the GR10 at its most remote — long days between beds, old mining ruins reclaimed by grass and scree, and some of the quietest refuges on the whole trail. If you want the Pyrenees without the crowds, this is where you'll find them.

It's also one of the tougher sections, with more ascent than most walkers expect from the daily distances. The reward is a proper thermal village at the end, Aulus-les-Bains, where a warm bath and a decent dinner feel entirely earned.

How this section unfolds.

Your route divides naturally into three parts — not by day, but by country. You climb onto the Spanish border ridge, then walk through the abandoned mining heart of the Couserans, then drop down through beech forest and stone bridges to a thermal village in the Garbet valley.

Where you'll stay

Remote refuges, then a thermal village at the end.

This section leans on mountain refuges and gîtes d'étape in the more isolated stretches, with a genuine thermal hotel waiting at Aulus-les-Bains. We choose places that are used to walkers arriving tired and hungry — the specifics depend on your pace and dates, as with every trip we build.

  • Half-board in the remote mining-country refuges
  • Walker-welcoming hosts who know the terrain
  • Drying space for wet kit
  • Breakfast big enough for the big ascent days

Every trip is planned around your dates and party, so we can't promise you a specific inn — but we can promise the kind of welcome that makes a walking holiday feel like a proper holiday.

Self-guided, fully supported

A self-guided GR10 Section 5: Luchon to Aulus les Bains, explained.

Self-guided means the walking is yours and the logistics are ours. You set off on the GR10 Section 5: Luchon to Aulus les Bains when you want, walk at whatever pace suits you, and stop where you like — there is no group to keep up with and no leader setting the schedule. Everything that makes an independent long-distance walk hard work to organise is handled before you arrive.

There are no fixed departure dates. Choose your own start day, tell us how many nights you want, and the planner rebuilds the 124 km route around it.

Your trail, whether you come alone or bring everyone.

We remove the awkward parts at both ends: quiet reassurance for a solo walker, and no unpaid-invoice chasing for the friend who gets a group moving.

Going solo

Independent, not unsupported.

We lend solo walkers a satellite GPS tracker. It updates automatically, even away from phone signal, so you can walk freely while the people at home follow your progress.

  • Fixes your position from satellites, not phone masts
  • Posts automatically every 30 minutes — nothing to remember
  • Keeps working in the glens, on the cliffs and out of signal

Things walkers ask us.

How fit do I need to be?

You'll want to be comfortable walking 15–20 km a day with around 1,000 metres of climb, on mountain terrain with some scrambling on rocky cols. This is one of the more demanding sections of the GR10 — the day from Fos to Araing Lake involves 1,680 metres of ascent, and the descents are long. If that feels steep, the Explorer pace stretches the trail to ten days at a more measured rhythm.

When should I walk it?

June to September is the realistic window. The route crosses cols above 2,000 metres, and snow can linger on the highest passes into June. July and August give the most reliable weather but are also the busiest. Early September is often the sweet spot: paths still clear, refuges quieter, and the high country starting to turn. We don't run the route before June or after early October because the higher cols carry serious snow risk.

Do you include luggage transfer?

Yes — between road-accessible accommodation, up to 20 kg per bag. The exception is the Refuge d'Araing at the end of Day 4: it sits beside a mountain lake with no vehicle access, so for that night you'll carry an overnight kit yourself. Your main bag waits for you at Eylie the next afternoon.

What kind of accommodation do you book?

On the Standard package, gîtes d'étape and mountain refuges with breakfast — small, well-kept, the kind of places where the gardien remembers your name by the second night. On Premium, village hotels and guesthouses where the trail passes through inhabited valleys. The Refuge Jacques Husson at Araing is dorm-only for everyone — there are no rooms on a mountain lake — but the food is good and the staff have walked the route.

Can I walk it solo?

Yes — the GR10 is well-waymarked (red-and-white blazes the whole way), and the section is busy enough in summer that you'll meet other walkers most days. We book single-occupancy rooms with a single supplement where the accommodation has them. The exception is the dorms at Araing — those are shared, but most refuges have a women-only option. The remote middle days are the ones where you'll go longest without seeing anyone — fine in good weather, worth checking the forecast.

What's the realistic total cost?

Our Standard package is £1,631 per person for the eight-day Hiker pace, based on two people sharing. That covers accommodation (gîtes and refuges with breakfast), baggage transfer where the route allows, a route pack with maps and notes, and 24-hour support. On the trail, budget around €25–40 a day per person for lunches, evening meals, and drinks. Most refuges offer a demi-pension — dinner, bed, breakfast for around €55–70 — which is the easiest way to handle food and lodging.

Is this a self-guided GR10 Section 5: Luchon to Aulus les Bains walking holiday?

Yes. Every GR10 Section 5: Luchon to Aulus les Bains trip we run is self-guided: you walk the route on your own, at your own pace, with no group and no guide. We do the planning and the logistics — an itinerary of 3 – 7 days built around the pace you choose, accommodation booked in your name along the 124 km route, your main bag moved between stays each day, GPX files and route notes for every stage, and a real person on the end of the phone while you're out there. You choose your own start date; there are no fixed departures.

What's the difference between a self-guided and a guided GR10 Section 5: Luchon to Aulus les Bains trip?

On a guided trip you walk with a leader and a group to a fixed schedule. Self-guided means the day is yours: start when you like, stop for lunch where you like, walk fast or slowly, take a rest day. The route is waymarked and you navigate with the GPX and notes we provide. Everything that makes a trip complicated — accommodation, luggage transfer, the shape of each day — is arranged for you before you arrive.

Can I walk the GR10 Section 5: Luchon to Aulus les Bains without a guide?

Yes — the GR10 Section 5: Luchon to Aulus les Bains is a signed long-distance route and thousands of people walk it independently every year. What most walkers want help with isn't navigation, it's the 124 km of accommodation, the bag transfers, and getting the daily distances right. That's exactly what we take off your hands, while you still walk it under your own steam.

Who books the accommodation and moves my luggage?

We do, both. We book walker-friendly B&Bs, inns and small hotels in your name at each overnight stop, with breakfast, and arrange door-to-door luggage transfer between them so you walk with a daypack. You'll get a full itinerary with every address, check-in detail and transfer time before you travel.

How many days do I need for a self-guided GR10 Section 5: Luchon to Aulus les Bains?

Most people take 3 – 7 days for the 124 km. Our planner lets you set your own pace and number of nights, so you can stretch the trip out with shorter days or compress it if you're used to back-to-back big days — the itinerary, accommodation stops and price all update as you change it.
