What's even more interesting is that each owner maintains a public easement, a shore path that circles the entire lake, all 21 miles of it. This was originally established in the 1800's so that the local Native Americans could hunt and fish around the lake, as was specified in their treaties. Today it is there for the public's enjoyment (and exercise. Yes, I have hiked the entire 21 mile distance. Once. Only once, but I've hiked large portions of it many times). Each owner maintains their section as they see fit. So parts of it have flagstones, parts are grass, parts are paved with various types of stone. Some look like this:
Others like this:
This is the path in downtown Lake Geneva:
And this is the path as it goes past one of the most impressive mansions:
The homes along the lake are, as I mentioned, gorgeous, and the only place to see them is either from the path or from a boat. The shore path is a wonderful opportunity to take a walk. If you're ever in the area, stop and walk a portion of the path. It's a truly unique experience!
