Hands down, one of the best zoos in the country, the Henry Doorly wins all sorts of awards every year for its design and activities. Start out at the largest indoor rain forest in the U.S., where toucans fly overhead as gibbons swing from the trees and all sorts of creepy, crawly things ooze about in the waters below. Play patty-cake with apes at the interactive gorilla exhibit, but be sure to let them win. On a hot summer day, cool off with hours of entertainment in the penguin exhibit. Then spend the night in the desert dome. Yes, sleep out with nocturnal desert creatures who rarely appear until the sun goes down. If possible, plan on spending two days at this world-class zoo. You won’t be disappointed. And if you can’t spend that much time, be sure to check out the penguin webcam when you get home. It’s almost as much fun as being there.
