Khao Lak dive centres, Khao Lak

Khao Lak Scuba Adventures (KSA) is one of the most established and best-loved dive operators on Thailand's Andaman coast. Running since 2003 and operating the well-known Manta Queen liveaboard fleet, KSA specialises in getting divers out to the very best sites in the region — the Similan Islands, Koh Bon, Koh Tachai, the legendary Richelieu Rock and the Surin Islands — in comfort, safety and great company. With a large team of multilingual, professional instructors and dive guides, they cater brilliantly for everyone from newly qualified divers to seasoned enthusiasts, which makes them our go-to partner for diving trips out of Khao Lak.

KSA lives and breathes the Similans, and their fleet is purpose-built for it. Their liveaboards run the full range of itineraries across the season, so whether you have three nights or five, whether you want a first taste of the Similans or a full expedition all the way to Richelieu Rock, there's a trip that fits. Boats are well run and sociable, the food is fresh Thai-European fusion cooked onboard (with vegetarian and vegan options happily catered for), and quality rental equipment from ScubaPro and Mares is available if you're travelling light. Snacks and fresh fruit between dives, experienced guides in the water and a genuinely friendly atmosphere round it all off.

KSA is a full dive-training operator with a large team of professional instructors, offering the complete range of courses from first-timer "try dives" and beginner certifications right through to advanced and specialty ratings. It's a superb place to learn or to level up — you can take a course and then put your new skills straight to use on some of the best dive sites on the planet. Whether you want to get certified before your liveaboard or add an advanced qualification to reach the deeper sites, they'll sort it out.

We work with Khao Lak Scuba Adventures to arrange Similan Islands liveaboards and diving trips as part of a wider luxury holiday to Khao Lak — pairing world-class diving by day with a beautiful beachfront resort to come home to.
