Hoover Dam Lodge
This property, which features a gorgeous view overlooking Lake Mead, was originally a mining parcel that was somehow overlooked when the federal government moved in to develop the Lake Mead Recreational Area and Hoover Dam. The land was known as Sullivan's Gulch and eventually became the Gold Strike Inn, with the casino opening in 1958. The resort was destroyed by a fire in 1998, reopened as the Hacienda, and made a comeback in 2015 as the Hoover Dam Lodge. It's the first casino you'll come across after crossing the border from Arizona on U.S. 93.
