An hour southwest of St. Louis, Meramec State Park has been the city's family escape valve since 1927 - and it may be the most complete reunion package in the Missouri park system. The park drapes nearly 7,000 acres of Ozark hills along a bend of the Meramec River, a gentle, gravel-barred float stream that canoes, rafts, and inner tubes drift down all summer. Beneath those hills run more than 40 caves - one of the highest cave counts of any state park in the country - including Fisher Cave, where ranger-led tours by handheld light pass calcite columns and bear-claw marks left in the mud by animals that denned there thousands of years ago.
What sets Meramec apart for a family gathering is that the infrastructure does the heavy lifting. There is a dining lodge above the river serving meals in season, a park store, cabins and motel-style rooms for the branch of the family that is done with air mattresses, and a large campground with electric sites, showers, and shady loops for the branch that is not. The on-site outfitter rents rafts and canoes and runs the shuttle, which converts the classic Ozark float trip from a logistics project into a walk-up amenity. Add a visitor center with a 3,500-gallon river aquarium, playgrounds, and 13 miles of trails, and three generations can each build their own perfect day within a half mile of each other.
The location seals it. Sullivan, five minutes away, covers groceries and pharmacies; Meramec Caverns - the billboard-famous show cave with its own Jesse James lore - is fifteen minutes up the interstate for a rainy-day spectacle; and Onondaga Cave State Park, another National Natural Landmark cave, is twenty-five minutes southwest. St. Louis relatives drive an hour; flying relatives land at Lambert and arrive before lunch. Missouri state parks charge no entrance fee, so the reunion budget goes to cabins and barbecue rather than gate tickets. The proven Meramec formula: cabins and campsites booked the day the window opens, a float-trip morning with every able-bodied relative in a raft, Fisher Cave tickets for the afternoon, and a dining-lodge dinner while the sun drops behind the river bluffs. Families have run that exact play for nearly a century, and it has not aged a day.

Things to do (with the family)
Hand-curated. Every entry links to its official source so you can plan without guessing.
Float the Meramec River
The park's on-site outfitter rents rafts, canoes, and kayaks and shuttles floaters for gentle gravel-bar floats back to the park - the definitive Ozark summer activity, easy enough for grandparents and first-timers.
Official source ↗Tour Fisher Cave
Ranger-guided tours (seasonal, ticketed) explore the park's showpiece cave by handheld light - calcite columns, soda straws, and ancient bear-claw marks scratched into the mud banks. Book ahead; tours sell out summer weekends.
Official source ↗Swim and skip rocks at the gravel bars
The riverfront day-use area opens onto wide gravel bars where kids wade, swim, skip rocks, and hunt crawdads while the adults hold down lawn chairs in the shallows. Free, unstructured, and the heart of every Meramec afternoon.
Official source ↗Visit the park visitor center
A 3,500-gallon aquarium of Meramec River fish, cave and karst exhibits, and ranger advice - the free first stop that orients the whole group and absorbs an hour of kid energy.
Official source ↗Eat at the dining lodge
The park's dining lodge serves meals in season with a deck above the river - the no-cook anchor meal that turns a campground weekend into an actual vacation for whoever usually runs the kitchen.
Official source ↗Hike the Bluff View Trail
The park's classic short hike climbs to limestone bluff overlooks above a bend of the Meramec - the golden-hour photo spot, and honest exercise without losing anyone for a whole afternoon.
Official source ↗Backpack the Wilderness Trail
A roughly 10-mile loop through the park's wild interior with backpack camps - the overnight challenge for the reunion's teenage-and-uncle adventure squad while everyone else keeps the cabins.
Official source ↗Fish for smallmouth and catfish
The Meramec holds smallmouth bass, goggle-eye, and catfish - fish the riffles at dawn from a gravel bar or drift-fish from a canoe. Missouri fishing permit required; the park store stocks tackle basics.
Official source ↗Day-trip to Meramec Caverns
The famous billboard cave at Stanton - 15 minutes away - runs walking tours through vast lit chambers with Jesse James hideout lore. The region's best rainy-day spectacle and a guaranteed grandkid hit.
Official source ↗Add Onondaga Cave State Park
A National Natural Landmark cave with dramatic formations, 25 minutes southwest - cave collectors in the family can bag two state-park caves and a commercial cavern in one weekend.
Official source ↗Bike and stroll the campground loops
Flat, shady park roads connect the campground, store, dining lodge, and river access - kids on bikes own the place by day two, and the evening family stroll to the river is a built-in tradition.
Official source ↗Join a ranger interpretive program
Seasonal ranger talks, night hikes, and campfire programs run near the campground - free structured entertainment that buys the cooks an unbothered dinner hour.
Official source ↗Canoe the quiet upper stretches
Away from summer raft traffic, the upper river runs are quieter - herons, turtles lined up on logs, and bluffs reflected in green water. Ask the outfitter for the calmer put-ins.

Good for
- St. Louis-area families - a true reunion park one hour from the city
- Float-trip reunions with on-site raft rentals and shuttles
- Cave lovers: 40+ caves in-park plus two famous show caves nearby
- Mixed lodging groups - cabins, motel rooms, and a big campground
- Multigenerational crews wanting a dining lodge and playgrounds
- Budget reunions: free entry, affordable cabins, cheap floats
Practical logistics
- Closest Airports
- St. Louis Lambert (STL) is about 1.25 hours away with nonstops from every major hub - practically a home-field airport for this park. Springfield-Branson (SGF) is about 2.5 hours for southwest-based relatives.
- Drive Times
- Sullivan 5-10 min · Meramec Caverns (Stanton) 15 min · Onondaga Cave State Park 25 min · St. Louis 1 hr · Columbia 2 hr · Springfield 2.5 hr. I-44 exit 226 puts the park entrance minutes off the interstate.
- Group Lodging
- Inside the park: cabins (rustic to modern, some riverfront), motel-style rooms near the dining lodge, camper cabins, and a 200+ site campground with electric loops and showers - reservations through the Missouri State Parks system and park concessionaire up to 12 months out. Summer weekends sell out early.
- Rental Companies
- Vrbo and Airbnb list river cabins and country houses around Sullivan, Stanton, and Bourbon; private resorts along the Meramec corridor add cabin clusters and group campgrounds for overflow branches of the family.
- House Size
- Park cabins run roughly $90-250/night sleeping 4-8; motel rooms less. Private river houses sleeping 10-16 run about $200-450/night in summer. Sullivan's chain hotels ($80-140/night) cover the branch that wants a pool and elevator.
- Peak Season
- Memorial Day through Labor Day is float season - warm river, full outfitter schedule, dining lodge open, and campgrounds selling out most weekends. Summer Saturdays bring heavy raft traffic to the river by late morning; float early or float weekdays.
- Shoulder Season
- September-October is the local secret: warm water into early fall, blazing bluff color, half the river traffic, and easy cabin availability. April-May brings wildflowers, strong river flows, and the first Fisher Cave tours of the season.
- Restaurants
- The park dining lodge covers meals in season, plus a park store for basics. Sullivan, 5-10 minutes away, has full groceries (Walmart), pizza, barbecue, and Mexican - closer supply lines than almost any Ozark park enjoys.
- Kid Friendly
- Excellent - gravel-bar wading, rented rafts that hold whole families, a cave tour with bear-claw marks, an aquarium visitor center, playgrounds, and bike-friendly loops. River rules apply: life jackets for weak swimmers and a designated watcher during gravel-bar hours.
- Accessibility
- The visitor center, dining lodge, store, and several campsites and cabins are accessible, and river-access points near the day-use area keep gravel-bar time within reach. Fisher Cave tours involve uneven, wet walking - ask rangers about tour accessibility when booking.
- Weather Window
- May through October is the full-service window. July-August run hot and humid (90°F+), which is exactly when the river and the constant-cool cave earn their keep. Spring floods can briefly close river access - check park alerts after big rains.
- Park Fee
- Free - Missouri state parks charge no entrance or parking fee. Float rentals, Fisher Cave tour tickets, and lodging are the only line items, and all are priced for families rather than tourists.

When to go
June through August is classic Meramec - warm float water, Fisher Cave tours running daily, the dining lodge open, and gravel-bar afternoons that define Missouri summer. For a reunion, mid-June and late August offer the full package with slightly saner crowds, and September is the connoisseur's pick: swimmable water, golden bluffs, and campground availability July never has. Whatever the date, book cabins and campsites the day the 12-month window opens, reserve the float with the outfitter for a weekday morning, and buy Fisher Cave tickets before the trip, not at the door.
Best for your group size
Small group · 10–25
Groups of 10-25 fit into a cabin cluster or one campground loop section, one outfitter raft flotilla, and one Fisher Cave tour slot - the whole reunion books in a single sitting.
Medium group · 25–60
Groups of 25-60 mix cabins and motel rooms with a campsite block, split the float into two waves, and reserve a picnic shelter as the daily anchor. Pre-arrange dining-lodge group seating for one all-hands dinner.
Large group · 60+
Groups of 60+ should hold the core at the park (every cabin they can get plus a big campsite block), overflow to Sullivan hotels, float in staggered weekday waves, and book a reserved shelter or lodge group meal as the single all-family event each day.

Reunion organizer tips
Book cabins, motel rooms, and a campsite block in one coordinated session the day the 12-month window opens - Meramec is metro St. Louis's backyard park and summer weekends evaporate.
Reserve the group float with the park outfitter in advance and ask for a weekday morning launch - you will have the river's best hours ahead of the Saturday raft flotilla, and the shuttle logistics are handled for you.
Buy Fisher Cave tour tickets early for a single afternoon block - tours are ranger-led, capacity-limited, and sell out summer weekends. The cave stays cool year-round, making it the perfect 95-degree-day escape.
Claim a riverfront day-use spot with chairs and coolers right after breakfast on gravel-bar days - shade trees by the water go first, and a staked camp is the reunion's natural gravity well.
Split the fleet on float day: rafts for families with kids and grandparents (stable, social, slow), canoes for the racers - then reunite at a designated gravel bar for the mid-float watermelon stop.
Book one dining-lodge dinner for the whole group early in the trip - it resets the cooks, and the river-bluff deck at sunset is the best table in Franklin County.
Life jackets on every weak swimmer at the gravel bars and on the river - the Meramec is gentle but it is a real river with real current. The outfitter provides them; use them.
Assign the visitor center as the arrival-day rally point - aquarium for the kids, maps and honest crowd advice from rangers for the planners.
Keep Meramec Caverns in your back pocket as the rain plan - 15 minutes away, fully lit, 60 degrees, and theatrical enough to make a washed-out float day feel like a win.
Do the grocery run in Sullivan on the way in - five minutes from the gate, full supermarkets, and the park store then only has to cover ice, bait, and ice-cream emergencies.
Send the adventure squad up the Wilderness Trail for one backpack night while the base camp holds the cabins - they return with stories, and the reunion gets two flavors of outdoors in one weekend.
Keep the float-crew manifests, cave-tour tickets, cabin assignments, and meal roster in Reunly - share the link once and nobody has to ask which raft, which tour time, or whose night it is to grill.

Frequently asked
Does Meramec State Park charge an entrance fee?
No - Missouri state parks are free to enter with free parking. You pay only for extras: float rentals, Fisher Cave tour tickets, lodging, and camping - all family-priced.
Can you rent rafts and canoes inside Meramec State Park?
Yes - the park's on-site outfitter rents rafts, canoes, and kayaks in season and runs the shuttle, so a reunion float requires no vehicle gymnastics. Reserve group floats in advance for summer weekends and ask for morning launches to beat the river traffic.
What is Fisher Cave and can kids do the tour?
Fisher Cave is the park's showpiece cavern, toured seasonally with ranger guides by handheld light past calcite formations and ancient bear-claw marks. Kids generally love it; the walking is uneven and damp in spots, and tours are capacity-limited ticketed events that sell out summer weekends - book ahead.
Does Meramec State Park have cabins and a restaurant?
Yes - the park offers cabins from rustic to modern (some riverfront), motel-style rooms, camper cabins, and a large campground, plus a dining lodge serving meals in season above the river and a park store. It is one of the most fully equipped parks in the Missouri system.
How many caves are in Meramec State Park?
More than 40 caves lie within the park - among the most of any state park in the country. Fisher Cave is the tourable showpiece; the rest riddle the park's karst hills, and nearby Meramec Caverns and Onondaga Cave add two more famous caverns within 25 minutes.
Is the Meramec River safe for kids to swim and float?
The park's gravel bars offer shallow wading and swimming areas, and the float stretch is a gentle, family-grade river - but it is unguarded moving water. Life jackets for weak swimmers, a designated adult watcher, and respect for post-rain high water are the standing rules.
How far is Meramec State Park from St. Louis?
About one hour southwest via I-44, exit 226 at Sullivan - close enough that St. Louis families have treated it as their reunion park since 1927. Flying relatives land at St. Louis Lambert (STL) and arrive in about 75 minutes.
Can you reserve a picnic shelter at Meramec for a family reunion?
Yes - reservable picnic shelters with tables and grills sit near the river and campground areas, booked through the Missouri State Parks system. Summer Saturdays go early, and a reserved shelter plus the adjacent gravel bars is the standard Meramec reunion setup.
