The Adventure Diver course is a subgroup of the PADI Advanced Open Water Diver course. Taking this course will get you one step closer to taking the Certified PADI Advanced courses. You will choose three courses from a long list of scuba adventures to complete this course. Once you complete these dives, you will earn your Adventure Diver certification. Some of the most popular courses that divers choose are Peak Performance Buoyancy, AWARE Fish Identification, Underwater Photography, and Deep Diver. But there are many other courses that may pique your interest as well.
