Learn to Dive

Start the first step at home to earn your first scuba certification with our PADI Open Water Diver course. This lifetime certification will allow you to dive all over the world and experience the wonders below the surface.


If you're unsure if diving is for you, try it out with our

PADI  Discover Scuba class.  This class is one session, 1.5-hour fun introduction to Scuba for ages 10+. You'll get a poolside introduction and 45 minute pool session to try Scuba without the commitment of the full Open Water Diver course.
