4–6 days at the hidden mountain lakes
A trip for outdoor adventure lovers.
A mountain adventure in the wild heart of the Pyrenees
Reserva ahoraOn this trail, you truly escape from civilization and immerse yourself in the remote mountain world. The route leads through the mountains of Cerdanya and Andorra, crossing three high mountain passes at around 2,500 meters and passing numerous small and large mountain lakes.
Thanks to the many opportunities for bivouacking, the trek can easily be adapted to your own pace. The trail can be completed in four stages, though this is quite demanding. A division into five or six stages is possible for those who prefer a more relaxed pace.
Most stages end at unstaffed mountain huts, but along the way you will also find three staffed refuges. This makes it easy to combine nights in a bivouac or tent with stays in mountain huts.
This circular trekking route to the hidden mountain lakes is a true adventure in a remote high-mountain landscape —perfect for outdoor enthusiasts and also suitable for families with children who already have some hiking experience.
