Catalonia's Hidden Gem: 200 Glacial Lakes at 3,000m — UNESCO Starlight Reserve Aigüestortes National Park
Nestled in the Catalan Pyrenees, Aigüestortes i Estany de Sant Maurici National Park is one of Europe's best-preserved natural environments.

That northern Catalonia boasts some of Spain's most beautiful and unique natural landscapes is common knowledge, but what many don't realise is that some of these places tell stories about our past that are even more impressive than their views.
Aigüestortes i Estany de Sant Maurici National Park is an immense jewel that brings together over 200 different lakes, surrounded by peaks reaching nearly 3,000 metres and the winding meanders (aigüestortes) that define this landscape. This exceptional combination makes it one of the best-preserved environments in all of Europe, with over 14,000 hectares of protected land.
But what truly makes this park irreplaceable is its origin: its rivers, lakes, and waterfalls were born from glaciers that completely melted after the last Ice Age some 15,000 years ago — the very glaciers that carved the terrain.
A Destination for Stargazing & Native Wildlife
All these conditions make this national park a must-visit for nature lovers, with sightings of endemic and exclusive species. The Pyrenean chamois, Pyrenean newt, Pyrenean desman, and the famous bearded vulture are just some of the standout names.
If birdwatching isn't your forte, there's a simpler way to enjoy the landscape. UNESCO has certified Aigüestortes i Estany de Sant Maurici National Park as a Starlight Reserve and Tourist Destination — meaning it's one of the best places on Earth for stargazing. The altitude, location, and complete absence of light pollution mean the sky can be admired effortlessly from anywhere in the reserve.
Settlements Over 10,000 Years Old
For those with an adventurous spirit or a love of archaeology, several teams of researchers have been studying the area over recent decades and have uncovered settlements dating back over ten millennia.
However, these sites are not easy to visit. They consist of open-air structures and settlements, some inside natural caves and others much more recent. They are visible if you find their exact location, but they are neither turned into museums nor signposted for hikers.
Rafting & Canyoning on the Noguera Pallaresa River
For those seeking a more intense and fun-filled escape, companies within the national park offer extreme water sports and activities only possible in environments like this. At very affordable prices, you can enjoy a family day out rafting on the Noguera Pallaresa River, or discover canyoning as you slide through different gorges and ravines along the river and its tributaries.
