The Lake Geneva Shore path first used by the Potowatomi is incredibly beautiful in itself. The bonus is that it runs next to a sparkling 28 mile spring fed lake! Start in any of the town on Geneva Lake: Lake Geneva (the name of the town, not the lake), Williams Bay, or Fontana. In the towns you can get on and off the path. Once you commit to the path and head toward the private homes and mansions, you will have to walk until another public access road. Once called the "Newport of the West" Geneva Lake was the home of the millionaires who rebuilt Chicago after the Great Fire. The homes are set back from the lake, but still could be a couple of miles from the access road, so no trespassing on the grounds!
It is a great workout! The terrain varies from sidewalks to gravel, dirt paths. Each owner has the responsibility of maintaining the path that goes through their property. It is hard to decide whether to focus on the lake, or the nature of the trails, or the beautiful homes. So, do it in segments, and more than once. You will enjoy every minute! Don't forget to take water.....and a little snack. Of course, there are great restaurants at any of the towns for very reasonable prices! Public bathroom facilities are available in the towns. Maybe your could spend a little money there to help those who provide such a lovely experience for you! Treasure the Beauty!
