The Strip, Las Vegas, Nevada
Mandalay Bay Resort & Casino has a 1.3 million gallon tank filled with more than 30 sharks and other marine animals. Adrenaline junkies who aren’t content simply looking at these creatures can actually scuba dive in the aquarium. The downside? Guests must already be a certified diver, but with the Sandtiger, Sandbar, and White Tip Reef sharks they could encounter (not to mention sawfish and stingrays), it’s probably for the best.
