Step into the Stone Age—the Hanna-Barbera version of it, anyway—at Flintstones Bedrock City in Williams, Arizona. Located 29 miles south of the Grand Canyon’s tourist-slammed South Rim, the 30-acre theme park and campground is a wonderland of dilapidated kitsch.

Although it isn’t technically abandoned, the 44-year-old roadside attraction sure has seen better days. Concrete statues of Fred, Wilma, Barney, Betty, Pebbles, Bam Bam, and Dino dot the property; once upon a time, stereos played stock phrases from each character, but no more. Some of the “stone houses” are boarded up or have leaky roofs, but you can still walk underneath a volcano hung with plastic skeletons, slide down the back of a two-story brontosaurus, load up on pink and yellow “dinosaur eggs” at the Bedrock grocery store, rattle the bars in a prehistoric jail, or pose next to a giant pterodactyl roasting on a spit.

The camp/RV park has showers, laundry, a convenience store, and a game room. The gift shop looks like it hasn’t been restocked in 50 years, which is fine if you’re in the market for a throwback souvenir. Fred’s Diner serves Bronto Burgers and Fishasaurus Sandwiches, but, uh, you might not want to go there. (No, you definitely yabba-dabba-don’t.) Entry to the park is $5—in our opinion, the best $5 you’ll ever spend near the South Rim.
