First-Time Scuba Diving in Costa Rica: Supervised Beginner Experiences

Try breathing underwater under direct PADI/SSI instructor supervision with zero prior experience. Important distinction: a 1-day introductory scuba experience (Discover Scuba Diving / Basic Diver) includes a pool or shallow-water skill briefing plus 1–2 closely supervised ocean dives (max 12 m / 40 ft), and does NOT qualify you to dive independently.

Duration Note: Listed tour durations (4 to 10.5 hours) represent the full door-to-door boat excursion including check-in, boat transit, and surface intervals—not continuous time underwater.
Medical & Site Rule: Final dive site selection and participation depend on the operator's on-water conditions assessment and standard diver medical screening.
