The chance to stroll among some 1,200 fluttering butterflies and 27 different species of birds inside this greenhouse-like attraction in Key West is one of those rare activities that’s as much fun for adults as it is for kids. The butterflies — all bred in captivity and from locales around the world — often land right on you. Glassed in, the exhibit is lush with waterfalls and tropical foliage complete with turtles and a koi pond. Don’t forget your camera! Kids under four-years old get free admission, and there’s discounted admission for kids up to age 12.
