My husband and I found this while taking the Citi View trolley for the day. It is free to get in and operates from donations. This is nice because most of the KW attractions are over priced. The Discovery center is a great place to learn a little bit about Florida's natural habitats. There is even a theater with some narrated underwater footage. I think that this is a spot for kids and adults. There are some really nicely done exhibits reflecting different types of habitats and some of them are interactive. This is no a huge building and does not take much time out of your day to experience so it is worth stopping by especially when taking a tour that stops right out front. There are also nice bathrooms here and drink machines if you need a break from the hot day.

Very interesting and informative of ocean life around the Key West waters. It really opens up your eyes of the life in the surrounding oceans. A great place to spend about an hour or so.

Admission is free, so I feel like I shouldn't complain, but the informational video was so dull and irrelevant, I fell asleep. The exhibits were ok, but there are many other more interesting places to see in Key West and its environs.

Another very worthwhile and free attraction. Especially enjoyed the coral reef and tropical fish tanks. Be sure to catch the short video, Reflections of the Florida Keys.
