The Most Beautiful Hiking Trails in Aigüestortes National Park

Discover the most beautiful hiking trails in the Aigüestortes Natural Park in Catalonia. I recently returned to this park after visiting it years ago. Read about my experiences, tips, trail descriptions, and places to stay in Espot.

About the Aigüestortes and Estany de Sant Maurici National Park

Nestled in the rugged foothills of the Pyrenees lies one of Spain’s best-preserved nature reserves: Parc Nacional d’Aigüestortes i Estany de Sant Maurici. Here, jagged granite peaks, blue glacial lakes, and pine forests dominate the landscape. With over 200 lakes and countless waterfalls, the park offers a rare interplay of water and rock.

The name Aigüestortes—“winding waters”—is not a poetic exaggeration, but an accurate description of the small valleys and mountain streams that wind their way through the park. The terrain is rugged, but accessible to anyone willing to climb and let themselves be guided by silence and steep trails.

If you’re lucky, you might catch a glimpse at dusk of the brown bear, which has recently returned here after years of absence. The capercaillie and golden eagle are also permanent residents of this remote ecosystem. Yet it’s not just the wildlife that makes this place special. The lakes—from the iconic Estany de Sant Maurici to the high-altitude Estany Llong—reflect more than just the clouds: they bear traces of the Ice Age, geological layers that become visible if you look closely. There are also guides in the region who can tell you all about it.

Back in the ’90s, as a student, I happened to end up in this park. No map, no experience with mountain hiking—just a poorly adjusted backpack and a vague sense of adventure. What I found there surpassed anything I had ever known: a wild, unspoiled mountain range where winding streams squeezed their way between pine trees and granite, and the lakes lay like mirrors, as if time had stood still.

I remember taking a photo of the snow-capped peaks of Els Encantats near Estany de Sant Maurici. I felt as if I had stumbled upon a secret landscape.

Now I was back. This time, it was a conscious decision; I was better prepared and had years of hiking experience under my belt. But my memory hadn’t romanticized it—it was just as overwhelmingly beautiful as ever. The park feels like a cross between the ruggedness of the Alps and the steep, rugged slopes of the Dolomites—but without the crowds.

Three Circular Hikes from Espot to Refugi d’Amitges and the Surrounding Area

Below are three hiking options ranging from easy to difficult. All three start from the official Prat de Pierró parking lot, 4 km from Espot. During peak season, you can take a four-wheel-drive Jeep taxi from Espot to be dropped off directly at Lake Estany de Sant Maurici. This shortens the hikes by over an hour and reduces the elevation gain by 150 m. More info: www.taxisespot.com
