Where to Camp Near Meramec State Park
The primary camping option is the state park's own campground, run by Missouri Parks. With 186 sites, most with electric hookups and some with full hookups, you can reserve via recreation.gov. Sites run $22–30 per night depending on season and hookup level. The park fills up quickly during summer weekends and fall leaf season, so reserve early.
Beyond the state park grounds, Sullivan offers several private RV parks within a short drive. These tend to fill the gap for peak season overflow or travelers preferring more amenities like laundry facilities, convenience stores, or dog parks. Sullivan is literally 1 mile away, so nothing here feels remote in a bad way—it's far enough to feel like real camping, close enough to grab supplies without a major drive.

Meramec Park Attractions
Fisher Cave is the tour centerpiece. It's the only cave on the park grounds open for public guided tours. At $8–12 per adult, these 1-hour walk-through tours show off stalactites, stalagmites, and the cave ecosystem. Reservations are required—book on recreation.gov ahead of time, especially on weekends. The tour is easy, not technical; families and older adults do this regularly.
Meramec Caverns, 3 miles away on Route 66, is a separate private operation and Missouri's largest commercial cave. It's the one famous for the Jesse James hideout legend (historically unproven but perpetually marketed). The main attraction is the "waterfall of lights" underground show—a 60-foot illuminated waterfall. Entry is $28/adult. It's touristy in the best Route 66 way, and worth the short drive if you're doing a multi-day trip.
The Meramec River itself is the real draw for many. The park permits canoe rentals directly on-site through concessionaires, or you can book with outfitters in Sullivan. It's a gentle float—perfect for beginners—with sandbars for lunch and wildlife viewing (deer, herons, turtles). A 5-mile float takes roughly 2–3 hours. This is classic Ozark paddling.
Hiking trails crisscross the park, ranging from short nature walks to more serious treks. The park sits on bluff-and-valley terrain, so views of the river gorge are frequent.

RV Logistics
Getting There: Sullivan is right on I-44 between St. Louis (west) and Rolla (east). If coming from St. Louis, take I-44 west for about 60 miles; the park turnoff is well-marked. The drive from St. Louis urban center is 45 minutes to an hour, making it the ideal weekend getaway.
Cell Service: AT&T and Verizon coverage is generally solid near Sullivan and the park. T-Mobile can be spotty. If you're banking on work-from-RV connectivity, confirm before booking a long stay.
Water & Dumping: The campground has water hookups at sites. There's a central dump station for full hookups. Water quality is good; the park is well-maintained.
Fuel: Sullivan has multiple gas stations. I-44 corridor has plenty of truck stops within 10–15 minutes if you're fueling a large rig.
Propane: Available in Sullivan at several hardware/supply stores.
Groceries & Supplies: Sullivan's main drag has a Walmart, Save-A-Lot, and local pharmacies. Fresh produce is hit-or-miss during off-season; plan accordingly or shop before leaving St. Louis.
Dog-Friendly Notes: Pets are allowed in the campground but must be leashed. Several of the private RV parks in Sullivan have dedicated dog parks. The town itself is relatively walkable.
