Planning a Meramec River float trip? The Meramec is St. Louis's backyard river — friendly, easy to reach, and built for groups and families.

This guide covers where to put in and take out, every outfitter on the river, live conditions, the best float segments with a river map, and tips for floating the Meramec with kids or dogs.

Float Tips
What to know before you go
Party Float tip: The Meramec is built for this. Wide, easy, great outfitters, gravel bars. Peak summer weekends are lively. That is kind of the point.
Chill Float tip: Timing matters. Weekday floats or early June hit a noticeably calmer river. Lower stretches near Sullivan run quieter.
Dog tip: The Meramec is very dog-friendly — mellow current, frequent gravel bar stops, and most outfitters allow dogs. Call ahead to confirm and book a canoe rather than a tube for easier dog management.
Segments
Where to put in, where to take out
Recommended stretches with mileage and notes. Best segment to start with is highlighted in the segment notes below.
Meramec State Park 5-mile loop~5 mi
The iconic Meramec day float. State park concession handles canoes, kayaks, rafts, and shuttle. The default first-timer trip — wide, easy, and finishes near Sullivan with cabins and camping at the takeout.
Meramec State Park to Meramec Caverns~6 mi
Float ends at the famous Stanton show cave. Half to full day depending on pace. Good combo trip for groups that want a cave tour after the float.
Onondaga Cave State Park to Meramec State Park~28 mi
The classic multi-day Upper-to-Lower run. Bookended by two of Missouri's best show caves with extensive bluff scenery in between. Plan two nights on gravel bars.
Steelville cluster (Upper Meramec)
Above Onondaga the river is narrower and shaded. Bass River Resort, Indian Springs, and the Steelville outfitter cluster handle put-ins through this stretch. Less crowded than the State Park section, especially mid-week.
Sand Ford to Birds Nest Campground~15 mi
Smallmouth Bass Special Management Area — trophy fishing stretch. More angler traffic than recreational floaters. Worth booking specifically if smallmouth is the goal.
Must-See Stops
Springs, caves, and bluffs to look for
Fisher Cave (Meramec State Park)
One of the few wild Missouri caves still open for hand-held lantern tours. The state park keeps it minimally lit and minimally developed — closer to actual caving than the show-cave experience down the road.
Meramec Caverns (Stanton)
Missouri's most famous show cave. Jesse James hideout legend, Route 66 history, multi-level lighted tour. The Caveman Floating concession launches from here. Touristy but worth it once.
Onondaga Cave State Park
Lesser-known sibling to Meramec State Park, with its own show cave and quieter river access. Ozark Outdoors Resort sits directly across the river. Often the best put-in for a 2-day Upper Meramec float.
Greens Cave
Natural cave 1.5 miles upstream from Meramec State Park with a small creek flowing out. Easy paddle-up exploration with a flashlight. Less marked than Fisher or Onondaga, so ask the State Park concession for directions.
Limestone bluff corridor
The Meramec is bluffier than its reputation suggests, especially the stretch through Meramec State Park and the Onondaga area. Peak color hits early-to-mid October — and the river runs lower and clearer in fall.
