There are a lot of opportunities for hiking in the Spanish Pyrenees, but does it get any better than the Carros de Foc? To be fair, it's also one of the best-known multi-day hut-to-hut hikes in the area. Rather obvious, because with 65 kilometers, over 3,500 meters of elevation gain, and 9 welcoming huts, an epic adventure awaits you on the Carros de Foc. Hiking in, quite a mouthful, Parc Nacional d'Aigüestortes i Estany de Sant Maurici doesn't get any better than this. Are you ready to discover the wild and adventurous side of Catalonia?

Once started as a joke by local hut wardens to visit each other, the Carros de Foc has now grown into a world-renowned multi-day mountain trek that is mentioned in many a guidebook as one of the most beautiful multi-day hut-to-hut treks in Europe. What makes the Carros de Foc so special? Why is it called "Chariots of Fire" in Catalan? Where do you start? Is the Carros de Foc something for you? Although well-known, one can still have a lot of unanswered questions about this epic trek. In this blog post, we'll answer them all for you!

What and Where Is Carros de Foc?

Carros de Foc is that epic hut-to-hut hiking tour that was not on your bucket list yet but will be after reading this blog post. No lies, there is no better way to discover the Catalonian Pyrenees. That answers one of your questions: You can find Carros de Foc in the Pyrenees, about 4 hours northwest of Barcelona, and because they are the Pyrenees after all, basically on the border with France. Carros de Foc is Catalan for Chariots of Fire and although no one knows why the trek carries this curious name, we dig it. The route was created in 1987 when the caretakers of the refuges in Aigüestortes i Estany de Sant Maurici Park decided to visit each other's huts, resulting in a beautiful circular hike, connecting all the mountain huts, "Refugi" in Catalan, in the area.

A great takeaway for Carros de Foc is that there is still this bond between the different refugis. The 9 huts are not only connected by 65 kilometers of trails, hikers are also able to collect stamps from each and every refugi, allowing for a great tangible memory to take home. The hike can be started at any of the participating refugis and you can choose your own pace and decide to stay in as many or few refugis as you wish. Having said that, it is of course to great to follow some sort of plan. If you keep reading, you will find one of the better self-guided itineraries for the Carros de Foc.

Is The Carros de Foc For Me?

Traversing from hut to hut in the Pyrenees on the Carros de Foc may not be for everyone. This is a high mountain hike that does require a bit of experience and respect for the mountains. Having said that, because you are staying at refugis, you will have more comfort than for example when you are hiking the GR11 in the Pyrenees. The refugis offer you a chance to recharge your mental and physical batteries and you will never have to stay in a tent. Also, since the Carros de Foc is a circular hike, you can take it as fast or slow as you want. It is recommended to do the Carros de Foc in at least five days, but it is also possible to do it in six. You could even only do half of the route.

It is important to know that although the Carros de Foc is a well-known route, it is not a perfectly marked one. Reason for this is that the route is that the park authorities of Aigüestortes i Estany de Sant Maurici have their own trail marking policy which does not include marking for the Carros de Foc. However, the directions to the independent huts are marked and with maps and/or a guidebook you can easily find your way. Is the Carros de Foc for you? If you are looking for an epic adventure in the Catalonian Pyrenees, this is totally for you!

Carros de Foc Accommodation: Staying in Refugis

At we like to do things properly and when it's about accommodation on treks in the Alps and the Pyrenees, this means you should stay in mountain huts. Refugi is the Catalonian name for a hut where mountaineers can enjoy a bed, a meal, and in, most cases, even a fresh draught beer or a good glass of wine. In Carros de Foc you can find 9 Refugis and what all these have in common is their fantastic locations. In the most remote spots in the Pyrenees, you can check into these safe havens.

On the Carros de Foc, not every Refugi offers the same standard. All of the huts have showers but only about half of them offer hot showers (against a small fee), only two can process card payments and not every refugi can be reached by car. Well, since you are on foot anyway, that's no problem. Now, in contrast to for example the Tour du Mont Blanc or the Alta Via 1, it is possible to not only have breakfast and dinner, but also lunch. This makes the Carros de Foc one of the only hut-to-hut trekking options with full board. This will save you a few extra grams in your backpack.

One clever way to both keep track of your visits and to have a tangible memory is the stamp card. For 30 Euros you get a high-quality map of Carros de Foc and a stamp card. Find a stamped example below.

What Is The Best Season for The Carros de Foc?

The Refugi on the Carros de Foc are open between June and October. This doesn't count for all of the Refugi, though. Some are only open between mid-July and mid-September, in line with huts in France, Austria, Italy, and Switzerland. No surprise then, that this is the best season for hiking in Aigüestortes. No huts, no refreshments, so you will be on your own. The best months are typically July and August, these are also the busiest. It’s peak season, so make sure to book as much in advance as possible. If you decide to go trekking in September, you’re still in for a treat and it’s not as busy on the trail. But this could also mean that some accommodations might be closed for the season already. Also, the days are shorter and the weather is significantly colder. If you want to set out on a long hike in a warmer area during this period, check out the GR221 in Mallorca.

Safe hiking tips for the Carros de Foc

When you go on walking holidays it is wise to be aware of a few points. Even if this is not your first time, you should never underestimate the mountains. Good tour planning and compliance with the regulations on the mountains will significantly increase safety. To ensure that your hiking holiday is a safe and enjoyable experience, here below you can find a list of 8 recommendations for safe hiking in the mountains:
  • Know your limits

    Hiking the Carros de Foc is the perfect outlet to escape from daily life. It is an endurance sport along with a beautiful nature experience with a positive effect on body and mind —as long as one is in good shape and has a realistic picture of one's possibilities and limits—. Never overestimate yourself or underestimate the route. Don't overdo it! Always choose the slower variant and take more time for your plans. Hiking under time pressure is not fun and at too fast a pace it can be dangerous. Be wise!

  • Plan carefully

    Good planning is half the work! Hiking maps, literature, the Internet and expert advice are invaluable when planning the route in the Carros de Foc and enable you to determine the length, altitude difference, difficulty and conditions of the hike. When planning group treks, the itinerary should always be planned for the weakest member of the group! The weather in the mountains can change incredibly quickly and rain, wind and cold all increase the risk factor. For this reason, always check the weather forecast beforehand and contact our trekking experts to find your way around before you start.

  • Be fully equipped

    Equipment is everything. In the most extreme case, it makes the difference between life and death, and in any case, it definitely makes the difference between having fun and having a bad time. Food and water, sunscreen and waterproof and warm clothes must always be in your backpack, as well as a first aid kit and a mobile phone with a full battery (in case there is an emergency). However, packing light makes walking easier, so don't take too much extra luggage with you. Your equipment should always be suitable for the terrain you'll be hiking on in the Carros de Foc.

  • Wear suitable footwear

    Good walking shoes protect your feet and provide a better fit. Shoes with a good fit, with non-slip soles, water-resistant and lightweight are a must for additional walking pleasure during the Carros de Foc. Trail running shoes are great for a weekend in the mountains, but on longer hikes or more technical trails, you'll want at least A/B hiking boots. That means it is recommended wearing high mountain shoes that are water-repellent with extra ankle support to prevent sprains.

  • Stay on marked trails

    Carros de Foc has endless marked hiking trails, which are controlled and maintained and should not be deviated from. It may be tempting, but it's not a good idea to take shortcuts or alternative routes through unmarked terrain. It increases the risk of disorientation and you're more likely to get lost and have accidents or fall in the mountains. Even steep slopes of packed old snow are often underestimated and dangerous. Are you in doubt? Better don't do it. For easy navigation we work with our trusted partner Komoot, whose interactive maps, also available offline, provide you with the necessary digital means to get from A to B. As a backup, make sure to bring a hiking guide or a paper map with you. FYI, 75% of stumbles occur due to carelessness on marked paths or roads, not in open terrain!

  • Take regular breaks

    Remember you're on a hiking holiday. Timely and regular breaks not only provide welcome relaxation but also make it possible to enjoy the Carros de Foc. The body needs a regular food and drink intake to maintain performance and concentration. Our advice is that if you have little time, it's better to follow the short itinerary than to speed up the long one.

  • Stay reachable

    If you are hiking solo or in small groups it is advisable to inform people back home about your plans, what route you are taking and when you plan to return. Even small incidents can lead to unpleasant emergencies so make sure you are available at all times. Bring a charged phone containing at least the phone numbers of immediate family members, your accommodations en route and the emergency phone numbers operating in the Carros de Foc.

  • Respect nature

    Leave no rubbish behind, prevent noise, stay on the marked trails, do not disturb wildlife or grazing animals, and respect protected areas.
