Landmark's pool was the largest in Las Vegas at the time of it's construction measuring 240 feet long and cost $200,000 to build. It held 400,000 gallons of water. Styled after a lagoon, it sported a center island with bridges spanning across to allow patrons to access it without having to go through the water. A lava rock wall was located at the west end of the pool with a waterfall flowing down into a smaller pool below at a rate of 4,000 gallons per second. At night, multi-colored lights would "dance" across the falls.

 

     The pool won the National Swimming Pool Institute's Gold Award. Visitors enjoyed laying out on the center island or behind the waterfall. In the early days, plastic bags with the Landmark logo were given out so guests could put their bathing suits away without tracking water through the hotel.
