Here's something to consider. The Grand Canyon Skywalk on the Hualapai Indian Reservation is something to see! It is somewhat hard to get to, but well worth the effort. From Las Vegas, take US 93 across Hoover Dam and continue SE. Turn on Pierce Ferry Road, then take Diamond Bar Rd. to the reservation. There are several miles of bumpy, dusty,
dirt road but in the end it is worth the effort. There are fees for the reservation and the Skywalk.
