Clark State Forest is Indiana's oldest state forest, a true outdoor gem. Covering nearly 26,000 acres, this sprawling natural area in southern Indiana offers a diverse landscape of rugged knobs, deep ravines, and scenic waterways, embodying a rich history of scientific forestry and conservation. It stands as a testament to Indiana's commitment to preserving its natural heritage and providing a sanctuary for both wildlife and outdoor enthusiasts.
Visitors can explore an extensive network of trails, including the renowned Knobstone Trail, Indiana's longest footpath, which offers challenging backcountry hiking and breathtaking vistas. The forest is also home to four distinct nature preserves—White Oak, Virginia Pine-Chestnut Oak, Alum Cave Hollow, and Outbrook Ravine—protecting unique ecosystems and experimental tree plantings from the early 20th century. These plantings showcase over 150 different tree types, such as cucumber magnolia, black walnut, sugar maple, and tulip trees. Keep an eye out for diverse wildlife, including white-tailed deer, raccoons, red and gray foxes, wild turkeys, and Eastern box turtles, along with a variety of bird species like woodpeckers and songbirds.
Whether you seek adventure on a challenging hike, a peaceful day of fishing in one of its seven lakes, or a quiet night under the stars in its primitive campgrounds, Clark State Forest provides an unforgettable escape. Its blend of historical significance, ecological diversity, and vast recreational opportunities makes it a cherished destination for connecting with nature and experiencing the serene beauty of Indiana's wilderness. Don't miss the panoramic views from near the Henryville Fire Tower, which on clear days can even offer glimpses of the Louisville skyline. Eager to name that creature?

Clark State Forest holds the distinction of being Indiana's first state forest, established in 1903. Its creation, initially as "The State Forest Reservation and Experiment Station," was a direct response to concerns about dwindling timber supplies in the state, which threatened local woodworking industries. The initial purchase encompassed approximately 2,000 acres and was designated for forest research and as a seedling nursery. Under the guidance of botanist Charles C. Deam, who served as state forester, the forest became a living laboratory for scientific forestry. Between 1905 and 1935, over 150 different tree species were planted experimentally, many of which can still be observed today. During the Great Depression, the Works Progress Administration (WPA) further developed the forest, building artificial lakes and bridges and establishing one of Indiana's largest Civilian Conservation Corps (CCC) cantonments, contributing significantly to its infrastructure and conservation efforts. Today, the forest has grown to nearly 26,000 acres, continuing its legacy of timber management, recreation, and watershed protection.
