Lake Fernstein is located in the Tirol alps in Austria near Fernstein pass at about 1000 meters above sea level. Together with Lake Samaranger it is in private property of Hotel Schloss Fernsteinsee. Diving is only permitted to hotel guests with two night stays at demi-pension. At checkin you have to show your diving logbook. One needs at least 80 logged dives. The ground of the lake is covered with sediments and if one touches the ground the visibility gets bad and al the plants get covered with dirt and may die.
