With a full PADI course lineup, it's easy to get stuck on where to start. Here's a quick way to figure out which course fits where you are right now.

Never Dived Before?

Start with PADI Discover Scuba if you just want to try breathing underwater in our heated pool before committing to a full certification. Ready to commit? PADI Open Water Diver is the certification that lets you dive anywhere in the world, and it's where almost everyone starts.

Already Open Water certified?

PADI Advanced Open Water takes you deeper and builds real-world skills through five specialty dives. It's the natural next step for divers who've done a handful of dives and want more confidence and range.

Want to handle problems, not just avoid them?

PADI Rescue Diver is our most challenging course, and it's the one divers talk about years later. Pair it with Emergency First Response for CPR and first aid skills that carry over outside of diving too.

Been certified a while, but out of practice?

PADI ReActivate refreshes your skills and knowledge without making you recertify from scratch.

Diving in Colorado specifically?

Every dive here is technically an altitude dive. Our Altitude Diver specialty course covers what changes about dive planning above 5,000 feet, worth taking before your first local lake dive.

Want to go further?

Once you're certified, our specialty courses (Nitrox, Deep Diver, Wreck, Drysuit, Night Diving, and more) let you build skills in whatever direction interests you. And if diving has become a real passion, PADI Go Pro is the path to teaching others.
