This is a great shop to dive with if you’re in Key Largo. They have smaller boats than most and will take you to some hidden gem dive sites. Looking forward to diving with them again. Hopefully this November for my wife’s birthday.

We had a wonderful day of diving with Ocean First Key Largo. They were incredibly friendly and the boat was first rate. We loved that Alisia was in the water with us---it's always nice to have a guide to follow. We had a great day of visibility. Water was a little chilly, but it's still March and to be expected. We HIGHLY recommend Ocean First in Key Largo!!! Top Notch Operation!

Jardin and his crew were incredible. Alisia was the most passionate and enthusiastic dive guide we've ever had — she made our 100th dive unforgettable.
- Robert S. (June 2025)
We had a wonderful experience! The crew took us to six incredible reef and wreck dives while we completed AOW training. We'll definitely return on our next Key Largo trip!
