Some mention

cell service

"Visitors consistently praise the cave tours (well‑guided, outstanding formations) and the park’s wooded, quiet campground with river access and good trails. Common drawbacks cited are limited cell service and the absence of full sewer hookups; some visitors note narrow access roads that can be difficult for large rigs."

Best Time to Camp at Campground

The campground operates with full amenities from April through October, when you'll have access to water hookups, hot showers, and all the conveniences that make camping comfortable for families and first-timers. This is peak season for cave tours and river activities, with mild weather perfect for exploring both above and below ground. Come November, the park shifts into its winter mode with reduced services through March. This quieter season appeals to experienced campers who appreciate fewer crowds and don't mind cooler temperatures—just pack accordingly and call ahead to confirm which facilities will be available during your stay, as opening and closing dates can shift slightly each year.

About Campground

Imagine descending into one of America's most breathtaking show caves in the morning, then relaxing by the Meramec River come afternoon. At Onondaga Cave State Park, your camping adventure combines the thrill of exploring a National Natural Landmark underground with the serenity of riverside trails and bluffs above.

Campground accommodates both tent and RV campers and includes primitive walk-in/tent-style sites as well as sites with hookups for larger rigs.

Historical SignificanceOnondaga Cave is designated a National Natural Landmark. No additional historical or cultural significance is detailed on the park's official page.

Natural Features and SceneryThe main attraction here is genuinely unforgettable: Onondaga Cave takes you into a living geological museum where active formations continue their ancient work, dripping and growing before your eyes. Massive stalagmites rise from the cave floor while delicate soda straws hang overhead, all illuminated to showcase nature's patient artistry. Back on the surface, lace up your hiking boots for the Vilander Bluff Natural Area, where trails lead to panoramic overlooks of the Meramec River winding through the valley below. The river itself beckons paddlers and anglers alike—whether you're floating past limestone bluffs in a canoe or trying your luck at landing smallmouth bass, the Meramec offers some of Missouri's finest waterway experiences just steps from your campsite.
