Charles Mears State Park is located in the quaint village of Pentwater along the Lake Michigan shoreline. Paved campsite lots are surrounded by fine sand, with a swimming beach adjacent to the harbor pier. Shore fishing is very popular at Pentwater Lake in the fall. Fishing from piers adjacent to the park is also a popular year-round activity. During the winter, Pentwater Lake provides excellent ice fishing. There is an interpretive trail about one mile in length for hiking. It winds around to the tip of Old Baldy, a wooded and sand-blown dune that provides an excellent view of Lake Michigan's shoreline, and the town of Pentwater and the boat harbor. Snowmobiles are not allowed on the hiking/cross-country trails, but the activity is supported in the park. It also has a metal detecting area. Pet friendly shoreline.
