Yes, you can swim in Lake Eibsee Germany. The lake is located near the Zugspitze mountain and offers stunning views of the surrounding alpine landscape. It's a popular spot for swimming due to its crystal clear waters and lack of motorized boats. Swimming is allowed from May to October each year, with lifeguards on duty during peak times. There are no showers or changing areas at the lake, so it's best to come prepared with towels and appropriate clothing for when you finish swimming.
