Situated to the south of Terfens in the Inntal Valley, the "Badesee Weißlahn" covers an area of 0.044 square kilometres and is surrounded by a large sports and leisure centre.
The lake is a popular meeting place in summer for locals and visitors alike in search of sporting action or simply a little relaxation. There is plenty to see and do for children and teenagers, from inflatable floating platforms on the lake to rock climbing and beach volleyball. Younger children and toddlers can splash around in a separate area with a small stream running through it. The Badesee Weißlahn has a large car park but can also be accessed by bicycle via the Inn Cycle Path.
