This beautiful park does not seem to belong in the Midwest. Our family returns at least once a year for the scenery and biking. We generally use the Rally group campsite and invite our friends to join us. This site is great due to the extra room for tents and proximity to the mountain bike trails. Keep in mind that these sites run a lot more per night and additional occupants that show are expected to pay the park over and above the daily rate. Also the park does not allow usage of the campground shower facilities if you stay on a Rally site.
We have also stayed in both the electric and primitive sites. Both are very nice and allow use of the nicest campground shower facilities around.
This campground is busy all season so book a long time in advance. Also they are very strict about dogs even in the large open areas so beware to keep them on leash at all times. No frisbee or fetch games allowed.
