Our Story

Alpharetta’s full service scuba & snorkeling shop located just 2 doors from Publix in the Flynn Center Crossing shopping center.
We faithfully serve the greater Atlanta area for all of its diving and snorkeling needs. Our six instructors have been teaching for a combination of over 100 years and are willing to dive anywhere that has water- from the dark water of Cooper River to the pristine water of the Red Sea. At 20,000 Leagues Scuba and Aquatics we truly believe that everyone who walks through our doors is a Dive Buddy For Life and will work to make sure that you feel like a part of the family no matter what lever diver you are.
