What is the Carros de Foc trail?
The Carros de Foc route is a hiking trail covering around 65 kilometres, with a total elevation gain of over 9,000 metres. It’s certainly not your average Sunday stroll, but it’s a spectacular journey that offers a unique way to discover the Pyrenees. The name means “Chariots of Fire”, and the route was created by the wardens of the nine mountain refuges. It is within the Aigüestortes i Estany de Sant Maurici National Park, so they could visit one another.
Of course, if you can’t complete the entire circuit, you can start the route at any of the nine refuges. There are also several options to make the experience more comfortable, including luggage transport and taxi transfers. Children can join in too; with a special pass, they can stamp at each refuge. For more experienced hikers, there’s also the Carros de Foc Plus route, which adds two extra refuges and several more kilometres.
