Planning a road trip with the kids or grandkids can be an adventure that’s part excitement, part logistics. For many, a must-see is Arizona’s Grand Canyon National Park, which is especially ideal to visit on a weekday in the fall. But if the kids aren’t into scenery and hikes, you’ll need some fun, low-key activities to break up the trip. Enter Bedrock City: a nostalgic roadside attraction where kids can play and grown-ups can relive Saturday mornings with The Flintstones. Plus, this attraction is paired with another family-friendly activity, filling up at least a half day.
