If you're planning a trip to Hilo and wondering if you can learn to scuba dive while you're here, the answer is yes—and it's easier and faster than you might think. Here’s a breakdown of how many days you really need to become a certified diver on vacation, especially on the Big Island.
The Standard Timeline: PADI Open Water Certification The PADI Open Water Diver certification is the most recognized beginner scuba course worldwide. It typically takes:
3 to 4 days total if you complete the full course in Hilo.
2 to 3 days if you complete the classroom portion online beforehand (called eLearning).
The course is divided into three parts:
Knowledge Development – Can be done online before your trip.
Confined Water Dives – Learn and practice skills in a pool or calm, shallow bay.
Open Water Dives – Complete 4 training dives in the ocean with your instructor.
Fast-Track Options Short on time? You have a couple of flexible options:
PADI Scuba Diver Course – Takes just 2 days and allows you to dive up to 40 feet with a pro.
Discover Scuba Diving – A half-day intro dive with no certification, perfect for trying it out.
Why Hilo Is Perfect for Learning to Dive
Calm, protected bays like Richardson's and Puhi Bay make great training environments.
Smaller class sizes mean more personalized instruction.
Incredible marine life and lava rock formations make even your training dives unforgettable.
Tips for Timing Your Training
Schedule your dives early in your trip to leave room for weather or rescheduling.
Don’t fly within 18–24 hours after your last dive—plan dive days before your departure.
Spread it out: Do your theory online before you travel, and use your Hilo time for diving!
Bottom Line If you have 2–4 days in Hilo, you have enough time to earn your scuba certification. And with the scenic underwater world just minutes from town, it’s one of the most rewarding and accessible adventures you can have on the Big Island.
Get ready to explore a whole new world—under the sea.
