I was traveling to The Grand Canyon to meet up with some friends from High School (We're 72 now) and they were staying at El Tovar so I drove my 2005 Born Free towing my JEEP from Tucson.  I originally booked at a KOA in Williams, but found out it was an hour to the park, so I looked for something else.  Found Raptor Ranch - only 1/2 hour to El Tovar so I booked it.  The place is pretty cool.  Just off of 64.  There is an attraction here called Bedrock City.  It's an homage to The Flintstones.  Kids today have no idea about how the Flintstones were part of our childhood.  It's great that they are preserving this memory.  The Ranch also does demonstrations of Birds of Prey three times a day.  Another educational opportunity.  The sites are pretty close together, but I wasn't bothered by my neighbors.  The sites are pull throughs and some back in.  Only about 40 sites.  There is a general store and a restaurant on the premises.  I'd recommend this campground if you're going to spend time at The Grand Canyon and have a tow vehicle.
