Great County Campground
Large campground with lots of trails and activities (although we camped in early May so many activities were not open). We would think that different times of year provide different experiences and we camped for a week in early May so we were able to experience quiet mornings and afternoons, great walks with our four legged camperand invredible views of swans, geese and ducks as they introduced their new little ones to the area.
The campground has a large beach, boat rentals, bike paths plus a BMX area and several playgrounds. Most of the activities (IE beach and rentals) open Memorial Day.
The showers cost 25 cents and we heard some people complain but we thought that the showers were immaculate and the time allowed was quite sufficient for a nice shower without wasting water(and having visited several National Parks with quarter showers, we were used to a cost).
We travel in a 42 ft motorhome and suggest if you are traveling in a large rig, drive through the park to find an appropriate site. We had called ahead but the site they had reserved for us would not have worked. Luckily, the people in our site had not left yet and we found a very good site for our stay. We are not Michigan residents anymore but we would not hesitate to return to Groveland Oaks!
