Shark Reef at Mandalay Bay

Shark Reef at Mandalay Bay is an underwater fantasy world in the middle of the desert. A see-through tunnel immerses the visitor in the midst of a water-world, with sharks swimming directly overhead. This isn't the cheapest attraction in Nevada, but it is worth the money you spend. Not only is this a visitor center, but it is also a facility for research and conservation of ocean life.
