Don't let the name "Secret Garden" fool you. Note that here, not only do they have dolphins but the "Secret Garden" is in fact home to the white tigers, leopards and lions. It was a nice break to typical Vegas scene. It is $20 a ticket, but for that you get to enjoy seeing the dolphins both above and below ground and the garden with the animals. They also have a gift shop and cafe so you can stay as long as you want.
