Havasu Falls, Havasupai Reservation, Grand Canyon National Park, Arizona, United States. I hiked down to these falls (11 miles from parking lot), and it was every bit worth it! You need to plan on camping out a few days. It's too much to do in a short period of time.
Montezuma Castle National Monument, near Camp Verde, Arizona ... One of my very favorite places in Arizona which is filled with many places that I love dearly. This spot has the power to take me to that time and place when the people wandered and lived here. I can feel them ... I feel as I have been one of them. The peace that fills me is like no other.
