Located in the province of Zamora, Lago de Sanabria is the largest glacial lake in Spain. Surrounded by lush forests and rolling hills, this lake is perfect for autumn visits when the foliage turns golden and crimson. Just 12 km from the medieval village of Puebla de Sanabria, it’s ideal for hiking, boating, and nature walks.

Tips for visitors: The lake is accessible by car, but the water is cold year-round, so swimming might be a brisk adventure! Autumn offers a peaceful atmosphere, perfect for photography or a relaxing picnic by the shore.

Lagos de Covadonga

In Asturias, the Lagos de Covadonga—Enol, Ercina, and Bricial—are nestled in the stunning Picos de Europa mountains. Famous for the Vuelta a España cycling race, these lakes are magical in autumn, when morning mists and changing leaves create a truly atmospheric setting.

Tips: Take the bus to avoid parking issues, and don’t miss the Sanctuary of Covadonga nearby. Sunset at the lakes offers one of the most enchanting experiences in northern Spain.

Lago San Mauricio

Lago San Mauricio, in Aigüestortes National Park, Catalonia, is a high-altitude gem surrounded by peaks soaring up to 3,000 metres. Autumn transforms the landscape into a tapestry of reds and oranges, perfect for hiking and photography.

The lake is a short walk from the Prat de Pierró car park. While winter freezes the waters, autumn provides crisp air, fewer tourists, and spectacular reflections of colourful foliage on the lake surface.

Laguna Rosa

Near Torrevieja on the Costa Blanca, Laguna Rosa is a unique pink lagoon within the Mata and Torrevieja Lakes Nature Reserve. The pink hue, caused by high salt content, contrasts beautifully with autumn skies, making it a photographer’s paradise.

Tips: The lagoon is shallow and highly saline—perfect for photos but not ideal for swimming. Visiting in autumn provides calmer conditions and vibrant reflections of the surrounding landscape.

Martel Lake
