Our Story

Alpharetta’s full service scuba & snorkeling shop located just 2 doors from Publix in the Flynn Center Crossing shopping center on McGinnis Ferry Road.

We faithfully serve the greater Atlanta area for all of its diving and snorkeling needs. Our instructors have been teaching for a combination of over 100 years and are willing to dive anywhere that has water- from the dark, waters of Cooper River offering ancient fossils to the pristine water of the Red Sea offering expansive tropical sea life and large aquatic animals.

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. Offering a unique combination of technical expertise, business expertise, fun and WATER, 20,000 Leagues Scuba and Aquatics offers unique experiences divers can’t find elsewhere. Our motto “Dive Buddies for Life” comes from our passion to share what we love with all of our Dive Buddies. Our icon – Splash – is also our inspiration to constantly grow as divers – even our Instructors take at least 1 new diving course annually.  

We offer premium brands such as Scubapro, Shearwater, SEAC, Sherwood, DUI and Dive Rite plus Akona, Henderson, Sealife, Genesis and Blue Steel and Catalina cylinders. We stand behind all of our brands by servicing everything that we offer for sale – and service all brands of SCUBA equipment.
