Yogi Bear Jellystone Park at Barton Lake is another of our favorite campgrounds. We usually spend 4 weekends in May and 4 weekends at the end of August into September. This is an award winning campgrounds and it shows. They believe in putting money back into the park and each year you can see many projects take place. One such project was the indoor swimming pool. You can roller blade or bike around the campground on smooth asphalt roads.
