There's a reason this place was featured on the cover on National Geographic, it is a MUST-SEE place! It's far from the easiest destination to get to but that is what makes it that much better. The town of Supai which is where the waterfalls are located have no roads that go there so it is only accessible via a 12 mile hike each way or $80 helicopter ride each way, it is one of the few towns left in United States that still gets their mail by pack mules. They only allow a certain amount of visitors each season which keeps it from being overcrowded so if you can manage to book a reservation, consider yourself very lucky. Their are campsites, cabins, and a motel, they will not allow you to hike in for the day, you must have an overnight reservation to hike in.
