A lot of locals are a member in a canoe/kajak club or they own one. It is a nice way to discover the lake or the river rhine and do some exercise at the same time. On a sunny day you won't be the only person on the water and other paddlers will greet you in a friendly way.
Discovering the area from the water will give you a totaly different perspectiv and you might spot things, that you wouldn't notice from the land. For sure you will be able to spot a lot of birds and fishes as well. Great way to spend a few hours outdoors and explore nature.
Too many cool places, where you can start your tour. It is up to you.
