Indiana Dunes State Park is a cool place to visit in Porter County, Indiana, USA. It's about 47 miles (75.6 km) east of Chicago. This park sits right next to Lake Michigan and is surrounded by the bigger Indiana Dunes National Park.

The park is famous for its amazing dunes, which are big hills made of sand. A large part of the park, about 1,530-acre (619.2 ha), is a special area called the Dunes Nature Preserve. This preserve has most of the park's hiking trails and beautiful dune landscapes.

Indiana Dunes State Park was created in 1925. It became a National Natural Landmark in 1974, which means it's a very important natural place. Like other state parks in Indiana, you need to pay a small fee to enter. In 2018–2019, it was the most visited state park in Indiana, with over 1.3 million people coming to explore!

How the Dunes Were Formed

The awesome sand dunes at Indiana Dunes State Park were made by strong winds blowing off Lake Michigan. When the wind carrying sand hits plants, hills, or other dunes, it slows down and drops the sand. Over a very long time, this process builds up the huge dunes you see today.

After the last Ice Age, the water level of Lake Michigan dropped. This made the shoreline move back, and new dunes started to form closer to the lake. Plants began to grow on the older dunes, and eventually, forests grew on top of them.

Sometimes, you can find "blowouts" in the dunes. These are spots where the wind has blown away the sand, revealing old, dead tree stumps that were once buried. The most famous blowout here is called Big Blowout.

A Look at Park History

The idea to save the Indiana Dunes started a long time ago. People realized how special this area was and wanted to protect it.

In the early 1900s, many people worked hard to make the dunes a protected area. They wanted to save this unique landscape from being developed. Their efforts led to the creation of Indiana Dunes State Park in 1925. This was a big step in protecting this natural wonder for everyone to enjoy.

Dunes Nature Preserve

Designated: 1974

The Dunes Nature Preserve covers about two-thirds of the state park, around 1,530 acres (620 ha). You can only explore this special area on foot. All eight of the park's hiking trails go into the preserve. These trails offer experiences from easy walks to tough climbs among the dunes.

Highlights of the preserve include:

  • The Tremonts: These are the three highest dunes in the park. They are Mt. Tom (192 feet (59 m) above lake level), Mt. Holden (184 feet (56 m) above lake level), and Mt. Jackson (176 feet (54 m) above lake level).
  • Blowouts: You can see large blowouts like Beach House Blowout and Furnessville Blowout.
  • The Marsh: This wet area has a bird observation tower, perfect for spotting different bird species.
  • Trails:
    • Trail 8 is 1.5 miles (2.4 km) long. It takes you over all three of the high dunes, starting from the Wilson Shelter and ending at the beach.
    • Trail 10 is the longest at 5.5 miles (8.9 km). It's considered a moderate trail. It starts at the beach and goes east along the shoreline. You'll pass Beach House Blowout and Furnessville Blowout. The trail then goes into the dunes through an area called Paradise Valley, following a creek and passing through the Pinery and along the marsh. You can reach the Bird Observation Tower from this trail. Trail 10 ends at the Nature Center.

The preserve was named a National Natural Landmark in 1974. It also has the Ancient Pines Nature Area, which is an old forest that has been uncovered by the wind blowing away the sand.

Understanding Blowouts

Blowouts are cool features formed by the strong winds coming from Lake Michigan. The wind picks up sand and piles it into dunes. As dunes grow, plants like beach grasses start to grow on them. These plants have strong roots that hold the sand in place, making the dune stable. Over time, other plants like sumac and juniper also grow, creating a protective layer over the sand.

A blowout happens when this protective layer of roots and plants gets a "nick" or a break. This can be caused by animal trails, people walking, or even a tree falling over. Once the open sand is exposed to the wind, the wind starts to move it again. It can dig under other roots and carry the sand away.

If the winds are strong enough, a large blowout can form. This can reduce the height of the dunes in a big area. The three biggest blowouts in the park are Beach House, Furnessville, and Big Blowout. Big Blowout has even uncovered an area of dead tree trunks, which is known as the Tree Graveyard.

The park also has a special Youth Tent Area for groups, separate from the main public campground.
