We visit a few times a year and like to do something non-gambling for the weekend, then hit the casinos and gamble and drink all week. Basically, we arrive late Friday, then have all day Sat./Sun. to enjoy the outdoors. Then we spend Monday-Friday in the casinos. So far over the years, we've visited Death Valley, Zion/Bryce, Red Rock Canyon, Mt. Charleston, and Valley of Fire. Are there any other hidden gems around we should try to visit for scenery and hiking? We've been to the South Rim of the Grand Canyon, but not the North Rim, which is much closer to Las Vegas.
