Thorny Ridge sits within Harry S Truman State Park on the shores of Truman Lake, offering a mix of site types from secluded spots to closer-together arrangements. The campground accommodates RVs up to 60 feet with full hookups available, plus tent sites without utilities starting at $15 per night. Three shower houses serve the area, though lines may form during busy periods.
Many sites provide direct water access and substantial shade, though campers should watch for the thorny branches that give the area its name. Early morning boat traffic on the lake starts around 5:30 AM, and tick activity can be heavy during warmer months. Reservations are accepted, and the campground connects to campsites near Warsaw for additional options in the region.
Description
There are 42 basic campsites in Thorny Ridge. The pads are between 47 and 60 feet in length and the four family sites have an extra pad between 52 and 55 feet long and an additional electric hookup. You will be close to the lake no matter which site you choose at Thorny Ridge because this campground is on a peninsula that juts right out onto the water. In fact, the boat ramp is at the end of the road by campsite 157. There is a parking lot at the boat ramp large enough to accommodate a trailer as well as an RV for the day while you take your boat out for the day. You will find the shower house, restrooms, and laundry facilities right in the middle of the campsite by the camp host site 166. The water, showers, and RV dump station are turned off during the off-season so bring your own water during that time. Pets are welcome but they have to be on a leash or restrained at all times.
