We loved Lehman’s Lakeside RV Resort. It is a great park to stay. We had the opportunity to camp here a couple of years ago.
It’s out in the country and easy to get to. The sites are wide, level and grassy and you park on gravel or concrete. The management was friendly and accommodating.
We had to change our arrival date due to an emergency and the campground was able to move things around so that we would be able to stay for two weeks in the same site. This is a wonderful park for dogs and walking.
I would recommend this park for Chicago visitors as you can drive to the town (10 min) and take the train downtown.
