The very first thing we wanted to do on our first trip to Key West was go to the Mel Fisher Maritime Museum featuring the shipwreck Atocha. There was a small entrance fee. The museum was small and dimly lit, however, it was bursting with treasure! It took about 45 minutes from start to finish, reading most of the information plaques. You could avail yourself of a self-guided audio system, but you don't really need it. The gift shop was unique; the sales help informative; memorabilia overpriced. All in all, I'm glad we made the stop.
