This park is a GEM!  Honestly, the campground is a bit busy for my liking during the summer, but it's a great place to camp in winter!  Facilities are decently maintained. 

The cord walk trail is great. The beach stretches so far and makes for a good afternoon of walking.  Nice nature center. Fun programs during the summer as well.  Lots of wildlife, especially birds, but we saw deer as well.   

*For a rainy day or chilly winter day, I like to check out the art museum in Sheboygan. Not big, but some unique stuff.
