I did the tour from the parking lot at the Hündlelift, all the way around the Alpsee. On the left side of the lake, the bike path is super easy and well-maintained. On the right side, I cycled over the top station of the Alpencoster. However, it's more for experienced cyclists and involves a lot of elevation gain.

The view over the Great Alpsee near the Alpe Alseewies is magnificent and offers a picturesque combination of mountains, water and nature. At this height you can see the Great Alpsee from a medium distance, which offers an ideal panoramic view. The largest natural lake in the Allgäu with clear, turquoise-blue water is embedded in a hilly, green landscape. Gentle hills, wooded mountain slopes and alpine meadows rise all around. The combination of idyllic lake, green meadows and surrounding mountains makes this bike tour particularly attractive.
