Itineraries
Krishna 3 operates seasonal liveaboard cruises throughout Thailand's Andaman Sea, primarily between October and May. Depending on the itinerary selected, cruises range from short 3-night escapes to longer expeditions exploring the region's most iconic dive sites, with departures generally from Phuket or Khao Lak.
Similan Islands
The Similan Islands National Park is Thailand's flagship diving destination, renowned for crystal-clear visibility, impressive granite boulders, colourful coral reefs and abundant marine life. Divers can expect encounters with turtles, Napoleon wrasse, reef sharks and vast schools of tropical fish while exploring world-famous sites such as Elephant Head Rock, West of Eden and Christmas Point.
Koh Bon
Located north of the Similan Islands, Koh Bon is famous for its dramatic underwater wall, deep pinnacles and seasonal manta ray encounters. The island attracts pelagic species while offering excellent opportunities to observe reef sharks, barracuda and large schools of fusiliers drifting through the blue.
Koh Tachai
Although now closed as an island destination, the offshore dive sites around Koh Tachai remain legendary among divers. Strong currents attract giant trevallies, barracuda, tuna, eagle rays and, during the season, whale sharks. The spectacular underwater pinnacle offers one of Thailand's most exciting advanced dive experiences.
Richelieu Rock
Often regarded as Thailand's finest dive site, Richelieu Rock is a horseshoe-shaped pinnacle covered with colourful soft corals, sea fans and an incredible diversity of marine life. Macro photographers will discover frogfish, ghost pipefish, harlequin shrimp and seahorses, while larger visitors may include whale sharks, giant barracuda and schools of jacks.

Similan Islands
Best time for diving
Mid-October - May is the optimum diving season on the Andaman coast (west coast). From early December until late April you can usually expect clear skies nearly every day. On average, you can expect 20 meters of visibility at The Similan Islands throughout the diving season.
Due to the likelihood of extreme weather during the monsoon months, the local authorities close the marine parks from May 16th until October 14th every year. Therefore the Similan diving season is from October 15th to May 15th.
About temperatures
Air: throughout the year, temperatures range from 25°C to 34°C with April through May being the hottest month and January the coldest
Sea: between 27°C - 29°C all year round, there are times when it drops to the mid or even low 20s, but in general these are rare or temporary occasions.
Wetsuit Recommendation
We recommend a 3 mm wetsuit year-round.
Diver requirement
Suitable for all levels. You can find out more information about diving in Similan Islands here : Similan Islands
