As the saying goes a long time ago a guest from the north would have made a difficult and unknown journey to the Achen Lake and would have been surprised by seeing the beauty in front of him and would have exclaimed: "ah, a lake!"
Over a length of 9 km extends the imposing, crystal-clear Achen Lake, also called "Fjord of the Alps", between Rofan and Karwendel Mountains. With an average width of 1 km and a depth of 133 m, it is an Eldorado for all kinds of water sports: sailing, windsurfing, kite surfing, swimming, paddling, everything is possible on the water.
In the summer with up to 21 degrees the lake is very suitable for bathing, it offers above all a wonderful hiking trail. There are 23 very varied kilometres, from an easy walking path to demanding stairs and climbing steps around the Achen Lake. In addition, the Achen Lake is one of the few lakes, which almost all banks are freely accessible. Tranquillity is guaranteed, as there is a motorboat-driving ban apart from the water rescue.
If you still would like to sail across the lake, you can do it with one of the 3 beautiful ships of the Achensee fleet with 5 stations connecting the villages of Pertisau, Maurach and Achenkirch. The TIWAG (Tyrolean hydropower) operates besides the Achensee shipping and the Gaisalm, also the hydropower station, which was put into operation in 1927, functioning with 5 Pelton turbines and is being supplied from the Achen Lake
