Your Travel Experience with Avellera
Self-Guided Swimming in Interlaken offers a refreshing way to experience Switzerland’s alpine lakes independently and at your own pace. Interlaken lies between Lake Thun and Lake Brienz, both suitable for swimming and known for exceptionally clean, drinkable-quality water. During the summer season, water temperatures typically range from 18–23°C, depending on the lake and recent weather conditions. Public beaches, lakeside lawns, and natural access points allow easy entry without special equipment.
Lake Thun is the warmer of the two lakes and is often preferred for longer, relaxed swims. Its water temperature is more stable, and gentle waves make it comfortable for casual swimmers. Many areas feature grassy sunbathing spots, shallow entry zones, and nearby cafés or facilities. The lake’s green-blue color and open shoreline create a welcoming environment for swimming and floating.
Lake Brienz is famous for its striking turquoise color caused by glacier minerals. The water is noticeably cooler and clearer, offering a crisp, invigorating swim. Entry points are often pebbled rather than sandy, and the lake deepens quickly, making it ideal for confident swimmers. The surrounding mountains create a dramatic, peaceful atmosphere with fewer crowds.
Swimming is done entirely at your own responsibility, as most locations do not have lifeguards. Water shoes are recommended, especially at pebble beaches. Sudden depth changes and cooler water temperatures should be considered before entering. Changing areas and restrooms are available at designated lidos, while natural spots offer a more wild experience.
This self-guided activity is ideal for travelers seeking nature, freedom, and an authentic Swiss lake experience. Whether you prefer warm, accessible swimming or a refreshing alpine plunge, Interlaken’s lakes provide memorable summer enjoyment surrounded by spectacular scenery.
