Aigüestortes i Estany de Sant Maurici is the only national park in the Spanish Pyrenees, protecting a high mountain landscape of glacial lakes, granite peaks, and ancient forests in the central Pyrenean range of Catalonia. The park sits far from any major Spanish or French city, and its high alpine terrain at elevations above 6,000 feet achieves Bortle Class 2 to 3 skies — among the darkest in the Pyrenees. The park takes its name from its twisted streams (aigüestortes) and the lake of Sant Maurici, and its more than 200 mountain lakes provide exceptional reflection foreground for Milky Way photography under Spanish Pyrenean peaks. The combination of lake reflections, granite spires, and Pyrenean darkness makes Aigüestortes one of the finest astrophotography destinations in the Iberian Peninsula.

The galactic core is visible from approximately April through October. The high Pyrenean location means alpine weather can change rapidly, with afternoon thunderstorms common in summer that typically clear by late evening. The park's interior roads are closed to private vehicles, requiring access on foot or by authorized taxi, which limits crowds and preserves the darkness. July and August offer the warmest nights and most reliable access to the high mountain terrain, while September brings excellent transparency and the beginning of the autumn color season.
