Happy Camping at Peninsula State Park!
One of my favorite places to camp! It's a beautiful campground, with great hiking trails and fantastic views of the clear waters of Lake Michigan. Because of how amazing this place is, it does fill up and it can very busy on the weekends, especially in the warmer months, like July and August. Depending on the time of the year, it's best to make a campsite reservation in advance by at least a couple of months for this place. But they do offer walk up campsites. When I went in late May/early June, it was a little cooler of weather so not as many campers! I enjoy camping in south nicolet bay campground; it has easy and close access to the swimming beach and camp store. My favorite campsite is 868 for its views, and then 856 for its privacy. The campsites are close to one another, but there tends to be lots of shrubbery and trees in between the campsites, so you don't see your neighbors too much.
When visiting, I would recommend trying to bring your bicycle to Peninsula State Park! It's a large park and has an wonderful bike trail called Sunset Trail, which travels throughout the state park and brings you right along the shores of Lake Michigan. Also, try to hike Eagle Trail! Even though its difficult, it has some beautiful views of the lake and bluffs. There is lots to do at Peninsula State Park, along with some beautiful scenery and has become one of my favorite places to camp since I was a child.
