Maps & Itinerary
Join the Manta Trust on this unique itinerary exploring the very best diving that Thailand has to offer, taking in the highlights of The Similan Islands, Koh Bon, Koh Tachai and Richelieu Rock as well as Koh Haa, Hin Daeng and Hin Muang to the south.
Sites on the eastern side of the Similan Islands tend to be sand covered fringing reefs predominantly made up of hard coral. The eastern sides of the islands also tend to have relatively gentle currents, making them ideal for divers of all levels and snorkelers.
On the west side of the islands the sites are a little different. Giant granite boulders tumble to the sea bed easily reaching depths of around 40m. Being more exposed to the open ocean, the dive sites on the islands’ west side can be prone to stronger and more unpredictable currents than on the east side but, the increased chance of seeing larger pelagics makes up for that.
Heading North, Koh Bon, Koh Tachai and Richelieu Rock provide probably the best opportunity for mantas on the whole trip.
Possibly some of the most underrated diving in the whole of Thailand, Moo Koh Haa (meaning ‘five island group’) sits almost halfway between Hin Daeng and Phi Phi and is part of the Ko Lanta National Marine Park. Ko Haa has varied dive sites and marine life, with pinnacles, walls, boulders and caverns hosting ornate ghost pipefish, morays eels, octopus, hawksbill turtles, sea horses, marble rays, and sometimes even leopard sharks.
Hin Daeng & Hin Muang
These two pinnacles (translating directly as Red Rock and Purple Rock) reach down to over 70m in open ocean, and are best known for manta ray and whale shark encounters. Almost perpetual good visibility and dramatic topography combined with huge fish numbers make for excellent liveaboard diving.
Your cruise director will schedule up to four dives per day; 3 day dives and a sunset or night. This totals approximately 30 dives over 11 days / 10 nights. The diving day is scheduled as follows:
- Light Breakfast followed by a briefing and Dive 1
- Full Breakfast, relaxation period, briefing and Dive 2
- Lunch, relaxation period, briefing and Dive 3
- Snack relaxation period, briefing and Dive 4, where possible
