The Aigüestortes i Estany de Sant Maurici National Park is located in the Catalan Pyrenees and is known as the land of a thousand lakes. It is home to over 200 crystal-clear, deep-blue mountain lakes (estanys), which rest in the rocky hollows of the high mountain landscape as silent witnesses to the last Ice Age. The name 'Aigüestortes' (Winding Waters) refers to the numerous streams and rivers that meander picturesquely in wide loops through the flat, high valleys, creating a unique wetland ecosystem. The majestic, often snow-capped peaks, including the distinctive double summit of the 'Els Encantats' (The Enchanted Ones), tower above dense forests of mountain pines and firs. In this remote and rugged environment, numerous protected animal species, such as the western capercaillie, the marmot, the golden eagle, and the Pyrenean chamois, find handy living conditions.

📋 Practical info
Getting there
Entrance to the Catalan Pyrenees park is typically via the gateway villages of Espot or Boí, which are easily reached by regional mountain roads. Private vehicles are restricted inside, so visitors commonly utilize the official 4x4 taxi service or hike from the entrances.
Best season
Summer and early autumn are the peak times for hiking, offering clear trails and beautifully reflective mountain lakes. Winter transforms the park into a snowy wonderland suited for snowshoeing, though many high passes become impassable due to deep snow.
Terrain & paths
The landscape features rugged Pyrenean peaks, glacial valleys, winding watercourses, and over 200 alpine lakes. Hikers navigate a network of well-marked trails ranging from gentle lakeside boardwalks to demanding, rocky ascents across high mountain passes.
What to bring
Dependable hiking boots, trekking poles, and versatile clothing layers are essential due to rapid altitude and weather changes. Bringing a detailed topographic map, sufficient hydration, and emergency rain gear is highly advised on all trails.
Parking
Visitors generally park their vehicles at designated large car parks outside the park boundaries in Espot or the Boí Valley. From these official parking zones, you must either walk in or take the authorized shuttle transport to the main lakes.
Safety
Mountain weather can be unpredictable, with sudden thunderstorms possible even on clear summer afternoons. Hikers should respect the high altitude, stay strictly on marked paths to protect the sensitive ecosystem, and inform someone of their route.
Time needed
A leisurely visit to Sant Maurici lake or a short valley walk easily fills a pleasant half or full day. For those attempting the famous multi-day refuge treks, dedicating five to seven days is normally required to traverse the park.
