The hiking trail around the Arendsee is certainly the best-known and most popular hiking trail in this region. There is so much to see and discover along the way. The proximity to the water is permanent.
The lake is 3.77 km long, max. 610 m wide and covers an area of 175 ha. It is approx. 6 m deep. At Lenzen and Leuengarten there are two, no longer official, swimming areas.
