The Manta Queen Liveaboard Fleet The Manta Queen fleet is KSA’s hallmark, consisting of several custom-designed vessels built to provide comfortable and professional diving experiences.

Manta Queen 3 Departs from Phuket for a different range of Southern dive sites.

KSA’s primary itineraries focus on the protected areas of the Similan Islands and Surin Islands National Marine Parks, which are renowned globally for their diverse marine life and stunning underwater topography. Richelieu Rock: Often hailed as one of the world’s best dive sites, this horseshoe-shaped pinnacle is famous for its vibrant purple soft corals and as a reliable spot for sighting Whale Sharks and Manta Rays during the season. It’s also a macro photographer’s dream, home to seahorses, ghost pipefish, and harlequin shrimp. Similan Islands: These nine granite islands offer a contrast between the West coast’s dramatic boulder formations (featuring swim-throughs and canyons like at Elephant Head Rock) and the East coast’s sloping, colorful hard coral reefs. Encounters with reef sharks and turtles are common. Koh Bon & Koh Tachai: Located between the Similans and Surins, these sites are known for attracting Manta Rays to their cleaning stations (particularly at Koh Bon’s West Ridge) and are excellent locations for spotting large pelagic fish. Boonsung Wreck: Closer to the mainland, this decommissioned tin dredger has become a thriving artificial reef, famous for its incredible density of schooling fish and a great site for day trips.

As an officially partnered Scuba Schools International (SSI) Dive Center, Khao Lak Scuba Adventures provides a full spectrum of diving education and certification programs, from introductory experiences to professional-level training. KSA follows the SSI training philosophy, which emphasizes “Comfort Through Repetition“ to ensure skills are mastered automatically and confidently.
