Großer Sonnstein

The Großer Sonnstein is a mountain summit rising to 1,080 meters that towers above Lake Traunsee in Upper Austria. The peak features steep rocky slopes on multiple sides, making it a dominant landmark visible from various points around the lake.

The mountain served as an important landmark in the Salzkammergut region as Alpine tourism began developing in the early 1800s. Routes across its slopes were used by travelers and merchants moving through the mountains.

Local hiking groups maintain traditional mountain festivals at designated spots along the trails, bringing together residents from surrounding communities.

The ascent starts from Ebensee church and follows a marked trail, taking roughly one and a half hours to reach the summit. The route is fairly steep, so sturdy footwear and sure-footedness are important.

A distinctive feature is a steel cable installation connecting this summit to the neighboring Traunkirchner Sonnstein, creating a technical mountain traverse above the lake. This route is used by experienced hikers seeking an additional challenge.
