Top Family-Friendly Activities in Key West, FL (What Kids Love!)

The best things to do in Key West with kids are the Butterfly and Nature Conservatory, the Key West Aquarium, a Fury dolphin watch and the Conch Tour Train. The butterfly conservatory is the gentle one for every age, a glass-domed garden where hundreds of butterflies float around your heads, best first thing in the morning. The aquarium is a small, air-conditioned stop with touch tanks, the dolphin boat suits school-age kids, and the Conch Tour Train shows you the whole island from a seat.

Key West Butterfly and Nature Conservatory

The conservatory is a glass-domed garden full of butterflies, a calm way to start the morning before the heat.
