Holland State Park is located in the U.S. state of Michigan, in Park Township, Ottawa County, four miles (6 km) west of the city of Holland. The park covers about 142 acres (0.57 km) on the northern side of the channel connecting Lake Macatawa with Lake Michigan, and consists of separate Lake Macatawa and Lake Michigan units. The former features an extensive campground, a beach on Lake Macatawa, and a public boat launch, and the latter features a smaller, paved campground, a pavilion with a snack bar and other facilities, and a broad sandy beach along Lake Michigan. The adjacent channel breakwall is a popular walk in the summer, though it is not intended for public use and can be treacherous during adverse weather. The park features several dune areas, picnic areas and playgrounds, as well as views of Holland Harbor and the Holland Harbor Light (Big Red).
In 2004, more than 1.2 million visitors came to Holland State Park, making it the most used park in the Michigan State Park system. Holland's pristine white sand beach, boat access to Lakes Michigan and Macatawa, and freeway access to large population centers such as Grand Rapids, Lansing, Detroit, and Chicago have all contributed to its popularity.
