Trekking in the Posets-Maladeta Natural Park

5 Days & 4 Nights - Self-Guided or Guided

This tour explores the Posets-Maladeta Natural Park, a protected area with the greatest concentration of 3,000 meter peaks in the entire Pyrenees. Our route is a 3-day circular trekking circuit around Pico Posets, at 3375 meters, the 2nd highest peak in the Pyrenees, staying overnight en-route in 2 mountain huts in superb settings in the high valleys.

This is a classic route in some of the most spectacular and remote terrain in the entire Pyrenees, the massive natural boundary between France and Spain.

  • Fantastic scenery – with so many big mountains around, numerous tributary valleys provide an incredible variety of terrain. France’s Pyrenees National Park is just on the other side of the ridge along the northern edge of the park. High summits, glaciers, magnificent waterfalls, canyons, and fertile lands of forests and meadows, offer a fantastic contrast of colours and landscapes – nature at its finest and a superb environment for any outdoor lover
  • Traditional mountain culture – The valleys in this area preserve traditional landuse practices in which the relationship between humans and the environment have evolved over the centuries in a balanced, intelligent and sustainable manner, for mutual benefit.
  • Glorious views, exuberant flora and abundant fauna – a nature photographer’s dream.  Marmots and chamoix observe us from rocky perches and birds of prey soar overhead, including the Lammergeier – one of Europe’s rarest birds of prey. A great location for alpine flowers, including the famed Eidelweiss – many mountain wildflower specialists consider the Spanish Pyrenees one of the best sites in the world.
  • A world-class mountain environment – for the Spanish mountaineering and climbing community, the Posets-Maladeta area is perhaps the country’s top location. Nearby Benasque is the home to the Spanish Mountaineering School. The area offers myriad opportunities for ice climbing, alpine and ski mountaineering, traditional and sport rock climbing, via ferrata, parasailing, mountain biking, etc.
  • Local guide option – a great way to add an extra measure of safety, access more adventurous terrain and learn more in-depth about the area’s fauna, flora etc. is to hire a locally born and raised professional mountain guide for the hike.We’ll arrange it for you!
  • Optional Posets summit ascent – add an extra day to climb to the summit of Pico Posets, 2nd highest in all the Pyrenees – a non-technical hike – with an elevation of 3371 meters. AUGUST ONLY.
  • Aínsa – where you’ll stay on your first and last nights – one of the most attractive historic towns in the Pyrenees, strategically located at the confluence of the Cinco and Ara rivers, with impressive views of the Pyrenees. Various accommodation options depending on budget. The town is easily accessible from Barcelona or Madrid. Various accommodation options in this area, or in the Valle de Chistau, just 10 km from the hike trailhead.
