I visited Zugspitze years ago and was amazed by the stunning turquoise water from the observation deck on top of Germany. Today, we rented e-bikes and rode from Garmisch-Partenkirchen to the beach, following the classic Rundweg. The sunlit water is beautiful from every angle. You can rent a boat, hike, bike, swim, or just relax on the beach. It's a great place to visit alongside Zugspitze. Just be aware that there may be traffic on weekends and public holidays.
Beautiful lake with a lovely scenic loop hike. The loop takes about 2 hours (less if you walk quickly). There are several spots with benches to stop and enjoy the views. I cannot wait to return to this beautiful spot!
