About 23 miles south of St. Louis, Imperial lies on the state line, with only the Mississippi River to its east separating it from Illinois. Originally called West Kimmswick, Imperial was part of the town founded in 1859 by St. Louis dry goods merchant Theodore Kimm. While the suburb offers little by way of tourist attractions (save the Mastodon State Historic Site), it does provide peace and quiet while remaining in close proximity to the urban bustle and cosmopolitan comforts of St. Louis. Though small, Imperial is well connected to the rest of the country: Interstate 55, which connects Chicago to Louisiana, and US Route 61, which runs from Wisconsin to Louisiana, run through it. Book an RV in Imperial today and follow where the road leads you.

Discover Imperial


Discover the Garden of the Gods and the Great River Road

Take your Imperial RV rental to the 1.5 million-acre national forest in southern Missouri named in honor of the state’s celebrated native, Mark Twain. Just an hour south near Rolla, the Mark Twain National Forest beckons adventurers of all stripes with abundant recreation opportunities. There are over 750 miles of hiking, horseback riding, mountain biking, and motorized-use trails, including parts of the Ozark Trail, that wind through it. Perennial streams where you can float a canoe or kayak year-round crisscross the forest for more than 350 miles. Parts of the forest are also designated as Wilderness and National Scenic River areas. Stay in one of the campgrounds and explore the forest for as long as you like.

Across the Mississippi River and state line lies the Shawnee National Forest, an hour and a half southeast by Imperial motorhome rental. Of its lush forests, rolling hills, open lands, rugged bluffs, lakes and creeks, Shawnee is most famous for its deservedly named Garden of the Gods Wilderness. Here you'll find cliffs and dramatic rock formations that have been sculpted by the elements over millions of years. The Anvil Rock, Camel Rock, and the Devil's Smoke Stack are some of its most spectacular rock formations offering unparalleled hiking and photographing opportunities.

St. Louis is, of course, on the road to everywhere: the Gateway Arch is a testament to that. Today you can follow in the steps of the pioneers by aiming west along Interstate 44 as it enters northeast Oklahoma, and from there picking up US-40 (historically Route 66) as it meanders its way to the Pacific. Or take a cue from the Mississippi River and follow US Route 61, otherwise known as the Great River Road, as it snakes all the way from Wyoming, MN, all the way down to New Orleans, LA. You'll find plenty of campgrounds along the way so you can break up your journeys into bite-size adventures with your Imperial travel trailer rental.

Where to Park Your RV

While there are only mobile home parks in Imperial, there are a handful of RV parks and campgrounds to be found within a 10-mile radius of town. Expand your search to 20 miles and you'll find a range of RV parks suitable for big rigs with amenities to match. The closest Walmart store is in Arnold, about five miles north, and could provide a spot to park the Imperial rental motorhome for the night.

Whether you go up or down the Great River Road, you're bound to find RV campsites along the way. The closest ones to Imperial are located along County Road (Jefferson County), DeSoto and Ste. Genevieve County, and across the state line in Baldwin and Ellis Grove, IL. All are within 30-60 miles away by Imperial rental RV.

What is There to See in the Gateway to the West?

The Mastodon State Historic Site is Imperial's main tourist attraction. Here, scientists found solid evidence in the Kimmswick Bone Bed that the American mastodon and other now-extinct ice age animals coexisted with humans in eastern North America. Learn about how paleontologists discovered this site and how the Missouri landscape looked in the prehistoric era, and marvel at the museum displays of fossils, artifacts, and mastodon skeleton replica. If you want to see where it all began, stretch your legs on the trails, including on one that leads to the site where the bones were found.

When you've had your time with nature, take your Imperial rental motorhome north and venture into the big city to enjoy the urban delights of St. Louis through a combination of JeffCo Express buses (from Arnold, the closest city to Imperial), Metro St. Louis buses, and St. Louis MetroLink.

Explore the Forest Park, the Missouri Botanical Garden and the national park surrounding the Gateway Arch. Browse the displays at the City Museum, Missouri History Museum, Mildred Lane Kemper Art Museum, and the Contemporary Art Museum, then join a tour around Anheuser-Busch Brewery. Step back in time and into the Old Courthouse where the Dred Scott cases were heard, and visit the Ulysses S. Grant National Historic Site, one-time home of the 18th president of the United States.

Start your journey today from the Gateway to the West. Find the best RV rental in Imperial, MO, enjoy the sights, smells and sounds along the way, and create lasting memories.
