Full name Sea Pearl Divers, a 5-Star PADI Center — exceptionally rated (4.9, 456 reviews), one of the largest and most established dive schools in San Juan. Services: full PADI course range (Open Water through Advanced), guided fun dives to uncrowded reef sites, night dives. Instructors Patrick, Ronellio, and Fares repeatedly named and praised — genuinely deep, consistent instructor quality across many reviews rather than one standout.
