The entire Blankensee is under nature protection. The plank bridge is the only part of the 280-hectare lake that is in contact with civilization. The Blankensee is surrounded by an intact reed belt, several hundred meters wide in places, and represents a valuable biotope. Great crested grebes and other rarer seabirds can also be observed from the much sought-after benches on the Bohlensteg. Or just eat a snack before you continue hiking in the Glau mountains...
