Historic Seaport at Key West Bight, from Greene to Grinnell streets at the north end of the island. Along a half-mile harbor walk are shops, restaurants, bars and a 156-slip working marina that is home to tall ships, ferries and catamarans which provide dive, snorkel and sunset cruises.
At Schooner Wharf which is at the end of the Harbor Walk you'll discover Schooner America, the fastest schooner in the world as it's said. Once it won the America's Cup and offers now 2 hr cruises. Especially the sunset cruise is worth to be considered as something you should do.
