Our story
20,000 Leagues was born from a simple idea: life is way too precious to spend it sitting behind a desk. Our founder walked away from decades in the corporate world to chase the water, and built this shop to bring the wonder of the underwater world to everyday people, not just a lucky few.
More than 70% of our planet is covered by water, and most of it has never been seen by human eyes. As divers, we get to see what almost no one else ever will.
You're weightless, breathing in a world most people will never see, face to face with creatures that look like they came from another planet. Every one of us still gets that rush, and we can't wait to share it with you.
And we've got the perfect launch pad. Our shop sits in Flynn Center Crossing on McGinnis Ferry Road, right in the heart of Alpharetta, a road trip from the Atlantic and Gulf coasts and a short drive from the Georgia Aquarium.

What our divers say
Amazing knowledge
“Amazing knowledge and friendly staff! Whether you're gear shopping or just looking to get more certs... this is the place to go. They have so many brands, you can tell they really care about their customers and truly love diving. I spoke with Mike before coming in and he was super helpful... I'm really glad I stopped in. Will be my go to scuba shop for sure!”
Jackie SmithDive buddies for life
“After I got certified in another state and then moved to Georgia I was really nervous about going out and diving. I didn't know where to go, who to go with and I almost stopped diving because of it. I started looking online and found 20k's website, booked a trip with them and OMG it was the best experience ever. I've went on a trip with them every year since.”
Hannah BrownThank you
“I just wanted to say thank you to Toni for such an enthusiastic and caring attitude towards your students. I felt comfortable putting the safety and well being of our daughter in your hands. She was really nervous about trying scuba for the first time and she came back from the pool with you beaming with excitement!!”
Brad BinghamBetter than new
“I want to thank Alex and his team at 20,000 Leagues Scuba. I dropped off my Scubapro regulator and they were able to service it pretty quickly and even caught a recall. The only shop I'll bring my gear to get serviced at.”
Anthony T MorelliHands down the best
“I've been to a lot of other dive shops in the area and I'll always keep coming back to 20,000 Leagues. Unlike other shops you can tell they really care about their customers, and go above and beyond to take care of them. Shops like 20K will custom fit gear to you, give you an actual community and they are worth the drive from the city to me.”
