Singing Hills is a nice private RV park near Mammoth Cave. We stayed one night. Sites 37, 39-44 are not shady, while the lower numbered sites have shade. The park streets and sites are gravel. The park was clean and quiet, and the staff was very friendly. They have a huge selection of DVDs and some fishing poles you can use for free. Stayed in pull through campsite#49 which was not shady but mostly level. It was a gravel site with grass on either side. There was enough parking for my 34 ft TT and truck. Neighbors are close. The site included: picnic table on grass and fire ring. Utilities: 20/30/50A electric in back. Water in back, good pressure. Sewer in middle with threaded fitting. AT&T had 2 bars of LTE and Verizon 1 bar of LTE service. AT&T Speedtest: 3 Mbps down, 1 Mbps up. Verizon Speedtest: 0.15 Mbps down, 0.13 Mbps up. Free WiFi Speedtest: 24 Mbps down, 15 Mbps up, but frequently drops out. Would stay here again We camped at Singing Hills RV Park& Campground in a Travel Trailer.
