Indian Cave earns its name. The park’s sandstone cave holds petroglyphs — human and animal figures carved by Native people, some believed to be thousands of years old — viewed from an ADA-accessible boardwalk with interpretive signs. It’s one of the few places in this part of the country where you can stand in front of rock art that old, on a bluff above the Missouri.
The rest of the park backs it up: 3,400 acres of rugged, wooded river bluffs with real elevation change for eastern Nebraska, 22 miles of hiking and biking trails plus 16 miles of equestrian trails, and the partially reconstructed town of St. Deroin, an 1850s settlement on the old Nemaha Half-Breed Reservation, with a schoolhouse, trading post, and cemetery.
Fall is the sweet spot — the hardwood forest colors up and the river views open. The park also hosts one of the region’s better-known Halloween events, the Haunted Hollow, if you’re planning an October trip.
