Shark attack! The Shark Reef Aquarium is exactly what it says it is: an aquarium filled with sharks. They have a couple different other types of wildlife, but the majority are all sharks and they are sharks of all shapes and sizes.You walk next to shark tanks, under shark tanks and you can even pet a stingray! It's fun for kids and also adults. I personally liked the Secret Garden at Mirage a lot better but this was still cool to see! If you're looking for an activity during the day while in Vegas, this is a fun option. It won't take you more than 20 minutes to go through.
