We faithfully serve the greater Atlanta area for all of its diving and snorkeling needs.

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 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.
