Located below St Anthony's Chapel and the forest cemetery, the forest lake on the outskirts of Oberachern is a popular recreational destination all year round. The lake itself - originally known as the "Allmendweiher" - was created in 1929 and has been repeatedly expanded. Today, the two sky loungers invite you to linger and enjoy the peace and quiet. There is also a fitness park and a lovely children's playground above the forest lake in the direction of the sports ground.
