Reasons to go

  • If you're looking for off-the-beaten-track hiking, you'll love the peace to be found on the trails
  • The reserve is remarkably untouched, making for breathtaking views of forests, valleys, waterfalls and hanging glaciers
  • You can see the highlights in day hikes, or take on a more challenging multi-day trek
  • The famous Carretera Austral passes through the park, making it easily accessible during a road trip 

Things to do


Numerous trails weave around the park, but no matter which you choose, you're likely to have the path to yourself. Although its reputation as a trekking destination is growing, Cerro Castillo remains a hidden gem, where the trails are blissfully quiet. Start in Coyhaique or Cerro Castillo Village and take a day or join a multi-day trek where you'll camp among the peaks, waking up to the rocks bathed in pink and orange. 

Our favourite route is the Cerro Castillo Trail, a 45 km trail that takes 4-5 days to complete. You'll hike deep into the forest, crossing cool streams on foot and seeking out hanging glaciers. Keep an eye out for eagles and the elusive native Patagonian deer which make their home here.

Horse riding

The people of Aysen are incredibly proud of their gaucho culture, and you can still explore the old mountain paths the way they were originally travelled, on horseback. Travelling this way means you can cover more ground and reach the truly undisturbed areas, where the forests, mountains and rivers stretch as far as you can see. You can even do a half-and-half trek, riding partway up the 1,600m climb towards the Cerro Castillo Lagoon before completing the last part of the ascent on foot.

Road trips

The Carretera Austral stretches all the way from Puerto Montt down to Villa O'Higgins, and passes through the Cerro Castillo National Reserve. This famous highway is mostly a dirt and gravel road, but offers some wonderful sights and scenery along the way.  A great way to explore the Aysen Region, but make a stop off in the park to trek to Cerro Castillo.
