If you are looking for the perfect hiking adventure in one of the most emblematic national parks in Spain, then search no more! Follow me on this Ruta de los Tres Refugios: 4-day trek in Posets-Maladeta Natural Park!

Located in the northern Province of Huesca, within the Aragonese Pyrenees, the Posets-Maladeta Natural Park is famous for having the highest concentration of peaks with an altitude over 3,000 meters. From Aneto (3,404 m), the highest mountain in this mountain range, to Posets (3,369 m)Perdiguero (3,221 m) and Alba (3,118 m) we won’t stop marveling at these summit’s breathtaking views. 

I have carefully organized this 4-day itinerary where each day we’ll find a new place to explore. By following the Tres Refugios route, we’ll discover the Chistau Valley, the Eriste Hill, the charming mountain lakes of Ibones de Batisielles and more!

Throughout this trip, participants will hike for approximately 6 hours per day and from hut to hut, they will get to see this natural paradise in all of its glory. Technically speaking this isn’t a difficult journey, but all participants will need to be physically fit and have some trekking experience.
