GRAND CANYON NATIONAL PARK, Ariz. — Visitors heading to the Grand Canyon lately know they are going to get two things when they arrive: breathtaking views and long waits, whether it is to get into the national park itself or to find a parking spot inside. A few frustrated tourists have even turned around and left.
The crowds haven’t just been coming to the Grand Canyon, where a sign ahead of the entrance gates warns of limited parking.
