Indiana Dunes State Park, National Natural Landmark and state park in Porter County, Indiana, US.
Indiana Dunes State Park is a protected nature reserve along Lake Michigan's southern shore in Porter County. The landscape combines sandy beaches with towering dunes and shelters a diverse ecosystem of plants and wildlife.
The protected area was established in 1925 to preserve the dune formations and natural ecosystems of the Lake Michigan region. This action recognized early on the importance of coastal habitats for conservation.
The Nature Center hosts educational programs about local wildlife adaptations and organizes an annual sand sculpture contest that brings together community members.
The site has multiple trails for different fitness levels and is accessible year-round. Visitors should prepare for changing weather and wear sturdy footwear, especially when hiking on the dunes.
The Three Dune Challenge invites participants to climb the park's highest sand formations, Mount Jackson, Mount Holden, and Mount Tom.
