[18121 - 18199] Old US Highway 66
Eureka, MO 63025
This is picturesque camping as it was meant to be - with lots of trees, a babbling creek, fireflies and a campfire (with s'mores!) Under a starlit sky. Located on Historic Route 66, this beautiful KOA is less than 1 mile from Six Flags St. Louis. It's less than 30 minutes from other St. Louis attractions, including the Gateway Arch, Forest Park, Missouri Botanical Garden, Museum of Transportation, Anheuser-Busch Brewery, Grant's Farm and riverboat rides on the Mississippi. Meramec Caverns, Purina Farms and wine country are also nearby. New this year: Geming mining station, fun cycle bikes, Full-time Director of Fun, activities/amenities. Groups enjoy the renovated pavilion and new air-conditioned meeting space. Railroad buffs can stay in the newly renovated red caboose.

The management and owner of this place do not care about their business or their customers. We had a terrible accident at this campground over the summer where a tree crushed and totaled our...
