Key Largo Scuba Diving FAQ
Everything You Need to Know Before Your Florida Keys Adventure
Why dive Key Largo?
With proximity to the Gulf Stream and a long protective landmass, Key Largo offers access to a wide variety of coral reefs, wrecks, and marine life within the Florida Keys National Marine Sanctuary.
What are your trip departure times?
We offer two daily two-tank trips. Morning check-in is at 7:30 AM with an 8:30 AM departure. Afternoon check-in is at 12:00 PM with a 1:00 PM departure.
How much water time do I get?
Each dive site has a 65-minute pool-open window. Actual dive time is typically around 50–60 minutes, depending on your preparation, air consumption, dive profile, and conditions.
Are dive guides included in the price?
No. We offer professional, paid instructors as guides for a small fee in 6:1 ratios. This avoids "cattle dives" and ensures a safer, more personalized experience.
What if it has been a long time since my last dive?
If it’s been 1–2 years, a hired guide is required. If over 2 years, you must complete a Scuba Skills Update in our pool before joining an ocean trip.
What marine life can I expect to see?
Expect to encounter tropical reef fish, sea turtles, eagle rays, barracuda, nurse sharks, moray eels, colorful coral formations, and many other marine species throughout the Florida Keys National Marine Sanctuary. Every dive is unique, and wildlife sightings vary with the season and dive site.
