Warren Dunes State Park is a 1,952-acre (7.90 km2) Michigan state park, located along the eastern shore of Lake Michigan in Berrien County. The park's large sand dunes and lakeshore beaches make it one of the most popular of Michigan’s state parks with an average of about one million visitors annually.
Large sand dunes are found throughout the park. Among the park's dunes are Mt. Fuller, Pikes Peak, and Mt. Edwards, with the most significant being Tower Hill, the highest point in the park, which stands 240 feet (73 meters) above the Lake Michigan. This dune is the one that is most visible to visitors, many of whom delight in scrambling up its slopes and rushing back down again. Easy access to the dunes make it a popular location to practice the sport of sandboarding.
The dunes and beach area was preserved by a local businessman, Edward K. Warren, who originally purchased the site as a favor to a friend who had encountered significant financial difficulties. By 1930, the Warren Dunes area had been taken over as a state park.
Warren Dunes is in the top five most popular camping destinations in the state of Michigan. The park contains two main campgrounds: Warren Dunes Modern and Warren Dunes Semi-Modern. Warren Dunes Modern has almost 200 campsites and is on the inland side of the dunes so the beach is just a short walk. Warren Dunes Semi-Modern is rustic and much smaller (only about 30 campsites). It has a variety of sites—some with high levels of privacy and others that are fairly close together. Both campgrounds are immensely popular and normally at full capacity in July and August.
Skygazing: Clear skies allow viewing of more stars than in most populated areas.
Clay painting: Walking about a mile up the creek which empties into the lake just south of the beach leads to large beds of light gray clay, through which the creek flows. Mixed with the creek water, clay makes body/face paint which can be worn home, but is much more commonly washed off by another swim in the lake. Clay painting has a negative effect on the park environment due to the amount of clay that is introduced to the creek water through man-made erosion and dispersion. Clay particles in the water create a turbid water environment. Turbid water can also have negative health effects if ingested; the higher the turbidity level, the higher the risk that people may develop gastrointestinal diseases. These health hazards are of particular concern given the number of small children and infants who play in the creek at the lake shore.
Creativity: This park is big and often not crowded, so a great testing ground for beach activities and equipment. For example, it was the inspiration and development site for the Beach Buggy, a self-contained mini-kitchen which could be wheeled to a family's water-side picnic site
