The Key West Butterfly and Nature Conservatory is a hidden gem among the bars and bustle in Key West. The small glass-enclosed habitat is fluttering with more than 50 species of butterflies, as well as colorful birds and a large tortoise. Different species of butterflies are active at different times of the day: In the mornings, some types bask in the sun and feed on the flowers and fruits; as the sun goes down, the largest butterflies on-site, the owl butterflies, become most active. Within the 5,000-square-foot conservatory, there are fountains, ponds, flowers, plants and trees. The best part of a visit to this tiny wonderland is interacting with the butterflies. If you put out your hand, they'll land right into your palm. The site includes a learning center and a gallery.
