PADI 5-Star Instructor Development Centre in San Juan, Siquijor — exceptionally rated (4.9, 457 reviews), one of the longest-running and most established dive shops on the island. Services: full PADI course range up through instructor-level training, guided fun dives, beachfront location cited as one of the prettiest dive-shop settings on Siquijor. Instructors Ken, Ian, Anthony, Alesso, Yeray, Seb, and Sai all individually praised across multiple reviews — genuinely deep bench of well-regarded staff rather than one standout instructor carrying the shop’s reputation.
