Achensee & villages

Lake Achensee, with a surface area of 6.8 square kilometres Tirol’s largest lake, is known for its intense shades of blue and excellent water quality. Its five villages are nestled in the magnificent natural landscape of the Karwendel and Rofan mountains. The region surrounding the mountain lake attracts visitors with plenty of active recreation, leisure and cultural pursuits.

Since tourism began in the Achensee region, it has been one of the most popular holiday and excursion destinations in Tirol. In 1887, the first steamship “St. Josef” was launched, which marked the beginning of the Achenseeschiffahrt. To this day, the boat cruises are one of the region’s major attractions for visitors to the region. The same applies to the historical Achenseebahn, a steam-powered cog railway that travels from Jenbach up to Lake Achensee in the summer months, covering 400 metres of elevation over a distance of 6.7 kilometres. The region is famous for the Tiroler Steinöl®, also known as the "black gold" of Lake Achensee. The fossil oil has been mined locally for over a century and has a very positive effect on the musculoskeletal system, skin and hair.

Lake Achensee - Heart of the region

Formed after the last ice age, the natural glacial lake is flanked by the mountains of the Karwendel and Rofan massifs and replenished by underground tributary streams. The setting of Lake Achensee with its dark blue waters backdropped by a stunning mountain scenery is reminiscent of a Norwegian fjord. The region is a paradise for nature lovers and offers amazing outdoor experiences year-round. Popular activities in summer include hiking, biking, sailing, swimming and even diving, while in winter the gentle slopes are ideal for family-friendly skiing. In addition, the region boasts a huge network of cross-country ski trails, which built the region’s reputation as "Tirol's top cross-country skiing centre".
