Go below the waves on a Sea Experience! The SCUBA shop is right down near Las Olas and the Beach. Reported as the premier dive center in South Florida, you can get your PADI licence here, go out for some snorkeling or stay dry and see the reef through a glass bottom boat.
The water is warm year round, and the wreck diving trips are said to be a lot of fun, so jump in! Call them at (954) 770-DIVE.
