Mounds State Park sits along the White River in Anderson, Indiana, protecting ten remarkable earthworks built by the Adena and Hopewell peoples nearly 2,000 years ago. The Great Mound, the park’s centerpiece, is a circular earthwork roughly 360 feet in diameter that once served as a ceremonial gathering place — one of the best-preserved prehistoric mound sites in the eastern United States.

Across 290 acres, the park balances archaeological significance with genuine recreational appeal. Over five miles of trails wind through ravines and old-growth hardwood forest, connecting the mound sites and offering surprisingly rugged terrain for central Indiana. The trail along the White River bluffs is a standout, particularly in fall when the canopy turns. Birders know Mounds as a reliable spot for warblers during spring migration, and the river draws anglers targeting smallmouth bass.

The park’s campground offers both electric and non-electric sites nestled among mature trees, making it a solid base for a weekend visit. Summer weekends fill up, so reservations are wise. A swimming pool operates seasonally, and the park naturalist runs regular programs on the mound builders’ history — worth attending for the context they add to what you’ll see on the trails.

Spring and fall deliver the best hiking conditions, though summer brings the fullest programming calendar. Winter visits are quiet but rewarding if you want the mounds to yourself.

Established in 1930, Mounds carries a 4.7-star rating across more than 2,500 reviews — a reflection of a park that genuinely surprises first-time visitors.
