Glaswaldsee Travel Guide

Glaswaldsee, often described as the 'blue eye' or 'black eye' of the Black Forest, is a captivating destination steeped in history and natural beauty. This 'Karsee,' or cirque lake, was formed during the Würm Ice Age, approximately 11,700 years ago, by glacial activity that carved out the basin from Bunter sandstone. The lake is nestled on the southeastern slope of the 966-meter-high Lettstädter Höhe, at an elevation of 839 meters.Originally known as the 'Wilder See' (Wild Lake), its current name, Glaswaldsee, is derived from glassblowing factories that were established nearby in 1587. These factories produced glass bottles, consuming vast amounts of wood from the surrounding forests. The lake was also historically used for timber rafting, with a sandstone wall raising the water level to facilitate the transport of logs down the Wolf valley.The Glaswaldsee lies within a 124-hectare nature reserve established in 1960, showcasing diverse flora and fauna. Fed by underground springs and a diversion from the Seebach stream, the lake's water is exceptionally clear. The lake itself is relatively small, with a surface area of approximately 3 hectares, a length of 220 meters, a width of 170 meters, and a maximum depth of 11 meters. Steep cirque walls, rising up to 120 meters, encircle the lake.Visitors can explore the lake via several hiking trails, with options for various skill levels. The area offers panoramic views, picnic spots, and opportunities to connect with nature.
