Last Frontier Dive is a PADI 5-Star IDC dive centre based in San Juan, Siquijor, in the Philippines, and one of the island's longest-running operations with roughly 28 years of local experience. The centre keeps groups small, capping fun dives at four divers per group, and runs a Green Fins-inspired reef-friendly briefing before every dive to protect Siquijor's coral, turtles and marine life. It offers boat and beach fun diving on local reefs, walls and turtle sites, Discover Scuba Diving for first-time divers with no licence required, and the full range of PADI courses from Open Water through Divemaster, plus specialties such as Enriched Air Nitrox and Peak Performance Buoyancy. Guided fun dives include tank and weights, with other personal gear arranged separately, and a local diving fee of ₱150 per diver per day applies on top of the listed prices for both fun dives and courses.
