Third stop on our quick trip across the Midwest was at Sundermeier RV Park, a large and well outfitted park located on the Missouri River in St Charles, MO which is just West of St Louis across the river. St Charles turns out to be notable for several things. Most interesting to us is that it’s the Eastern terminus of the Katy Trail, a 237 mile rails to trail across most of the state of Missouri. The Katy Trail is the longest rails to trail in the US, and over half of it follows Lewis and Clark’s path up the Missouri River. See more about the Katy Trail here:

Sundermeier RV Park is also located within walking distance of a couple of interesting tourist spots. First, it backs up to Frontier Park, a nice city park along the Missouri that houses the Lewis and Clark Boathouse and Museum ( The museum has full size replicas of the boats used by the expedition, as well as exhibits on the expedition, local Native Americans, and Missouri River habitat. Second, it’s walking distance to the site of Missouri’s first state capital building, a building that’s now state owned and housing reenactments and interpretive programs. See more about it here:

Sundermeier is a relatively large park, with gravel parking spots and roads. It has nice clean bathrooms and showers, a small supply shop, and event facility for group gatherings. Prices are on the higher end of our price range, $59/night for a pull through spot, with a 10% Good Sam or Military discount offered. The staff was friendly and helpful, and takes great care of the campground.
