Caves define the draw here. Onondaga Cave State Park Campground in Leasburg, Missouri sits along the Meramec River and gives campers direct access to guided tours of Onondaga Cave, a walking tour that runs roughly 90 minutes through well-lit passages with maintained paths. The cave closed seasonally for bat hibernation, so check tour availability before booking if that's your primary reason for coming. Campgrounds around Onondaga Cave State Park fill a range of styles, but few combine cave access with full hookups at this price point.
The campground meanders through hilly terrain and runs long enough that sites at different points along the road feel distinct from one another. RV campers have the advantage here: large concrete pads, full hookups, and a 45-foot maximum length make this a practical overnight stop. Tent campers get the same concrete pads and fire rings, but as Annie C. notes, "the trees are along the back of the camping row," which limits privacy and hammock options. Sites on the basic loop, numbers 1 through 13, sit close together and work better for groups than for campers wanting separation. Sites farther northeast of the playground tend to have more breathing room when the campground fills.
Bathrooms and showers draw consistent praise across multiple years of reviews. The facilities are well-maintained, with shower passes available for purchase from the camp host. Beyond the cave, the park has hiking trails, river access, kayaking, and fishing. The Meramec River bank is narrow in places, so don't expect to spread out along the water during busy weekends. Water shoes are worth packing.
The lower campsites sit close to the river but are prone to flooding after heavy rain. Site 65, near the entrance, has been flagged by multiple campers as slow to drain after precipitation. Off-season visits in spring or fall tend to mean quieter nights and more available sites. Reservations are accepted, and weekend stays may require a two-night minimum, so confirm the policy when booking.
