Sponge docks is the place which most of the people visit first. It’s only a quarter mile north of the historic district. Here you can eat, shop, take cruises to the Gulf of Mexico, or go deep-sea fishing.
Besides numerous shops and restaurants, there are 2 museums here. Coral Sea Aquarium maybe a good place to visit with kids. A scuba diver feeds sharks at 11:30, 1, 2:30, and 4 PM. In my opinion, Florida Aquarium in Tampa is much better.
Open daily 10 to 5. Admission fee $4.75 for adults, $4 seniors, $2.753 for kids 3 to 11.
Spongeorama – Admission is free. You can buy a sponge here (but most likely you’ve bought it already on the docks) and watch video about sponge diving (very old and boring). Open 10 to 5.
