My family is this, 30 years old, I have been to the canyon twice, there is some moisture, because the virgin forest inside, of course the air is very good, are steps, from the entrance, ask for money, from the exit do not have money, but the exit entrance is far away, if you drive, go out from the Grand Canyon, Also take a taxi to the entrance! Enjoy the natural scenery is worth a visit! There is a gold ancient town nearby. The gold ancient town has nothing to say. It is not interesting, but foreigners, it is not easy to come and see!
