Getting Outdoors

The Lower Meramec River is rich in spotted bass, channel catfish, flathead catfish, carp, drum, gar, walleye, crappie, bluegill, longear sunfish, and bass. A Missouri fishing license is required for fishing in Meramec River. 

RV camping at Castlewood State Park is great for boaters. A concrete boat launch ramp provides access to the river, and small, light, non-motorized boats like kayaks, canoes, and small boats are preferred. There is a sand bar at the base of the ramp, and when the water levels rise, the ramp is closed. Check with the park office about boating regulations before you take your watercraft into the river. 

Put on hiking boots and set out to explore over 26 miles of hiking, mountain biking, and horse riding trails. The trails differ in length, and difficulty levels and a few of the more popular ones are the Al Foster Trail that covers 4.7 miles, Castlewood Loop that’s shorter at 2.75 miles, and Chubb Trail that is 6.5 miles long and perfect for hiking, biking, and horse riding.
