Swim with Sharks or Enjoy a Roof-top Pool at Golden Nugget's H20 The Golden Nugget Hotel and Casino Pool is located in the heart of Downtown Las Vegas and is called H20. It is one of the top ten pools in the world on several lists, and its design with three levels and two pools leaves little to be desired. Level one allows you to swim with sharks in the shallow end (they're behind glass) or climb to the third deck to slide through the shark tank in a tube. While on the third floor, pay a little more to enter the adult pool area, no kids allowed. This luxurious rooftop pool area has day beds, cabanas, a bar, and very unique see-through wading pool for those relaxing, drinking and partying. Gaze out at the Downtown Las Vegas skyline as you get served a medley of food and adult beverages.
