Some Similan dives in Thailand are reputed to be the most beautiful in the country (well above Koh Tao or Koh Phi Phi for example), so I had to do them! The Similan Islands and Richelieu Rock can only be done on liveaboards since Khao lak or Phuket. If you are a beginner, you can do a diving day to do a discovery dive, but you will not really see the Similan Islands ... For more experienced divers, the trip is nice, but I would not classify it in the top 10 of Asia, Instead, go to Indonesia (Raja Ampat, Komodo), Malaysia (Sipadan) or Philippines (Tubbataha, Apo reef)

Context: the Similan Islands are part of my 3 month diving trip to Asia during which I wanted to make all the most beautiful spots! I did a 5 day liveaboard which comprised of 18 dives.

Where are the Surin Islands?

  • Even further North are the Surin Islands.
  • They are also beautiful, but you don't dive there.
  • To the East of these islands is a very well-known site: Richelieu Rock.
  • It is actually a submerged pinnacle, which we see the "top" only at low tide!
  • Some liveaboards of the Similan Islands often go to Richelieu Rock and in the Surin Islandsbut again, they are technically not part of the Similan Islands.

THE SIMILAN ISLANDS DIVING REVIEWS

How is diving at the Similan Islands?

plongee-iles-similan-thailande-seiche

  • Similan Islands, Koh Bon, Koh Tachai and Richelieu Rock are without a doubt the most beautiful dives that you can do in Thailand
  • Whether at the level of number of pelagics, of the diversity and some preservation of coral, of the site topography or rare species.

Similan Manta Rays in Koh Tachai and Koh Bon

  • On the islands of Koh Tachai and Koh Bon you have great chances to see manta rays !
  • I did 3 dives in Koh Bon (on the “Dome” site), and I saw manta rays every time! It was really great !!

Whale shark Similan Island at Richelieu rock

requin-baleine-mexique-la-paz

  • The best time to see whale sharks at Richelieu Rock is of January to April.
  • Unfortunately for me, I went there in November and I haven't seen one…
  • But apparently it is very common to see whale sharks at Richelieu rock, especially between February and March.

Large pelagic Similan Islands

plongee Similan 20

  • The Similan Islands are home to a lot of pelagic : groupers, barracudas, jacks, dogtooth tuna, batfish, snappers, triggerfish, clownfish, stingrays, lions fish, scorpion fish, fusiliers, octopus, cuttlefish ...
  • Some reef sharks and the leopard sharks are supposedly present, but I have not seen ...

Similan Islands Wrecks

  • plongee Similan 10You have several shipwrecks near the coast of Khao Lak : the Boosung, the Premchai, the Sea chart and the T13.
  • Some liveaboards often end their turn with one or two of these wrecks.
  • I did Boosung wreck and Premchai wreck. These are not huge cargo ships that couple your breath upon arriving, but both are bursting with life : moray eels, nudibranchs, scorpion fish, juveniles of all kinds (barracudas, angelfish, trunk fish ...)

DIVING CRUISE SILILAN ISLANDS IN THAILAND

Liveaboard Diving Info on Similan Islands in Thailand

manta-queen-7
Manta queen 7
  • Some Similan Islands are located far enough from the coast, so it's hard to go dive to the day (excursions are offered in high season, but it's really a long day).
  • All centers therefore offer liveaboards  (of liveaboards) 3 to 7 days, the most common being 4-5 days.
  • Departure from Khao lak or Phuket.
  • 10h of navigation about to get to the first sites.
  • There are many cruise ships for the Similan Islands, you can find them all on liveaboard.com.

From where to take a cruise to the Similan Islands

  • Some liveaboardsof the Similan Islands leave from Khao lak and Phuket.
  • I advise you to do it from Khao Lak, it is closer and much cheaper.

Choosing a Liveaboard to the Similan Islands: There are Several Options 

croisiere-plongee-similan-liveaboard-bavaria
Bavaria
  • Liveaboards do not all go to exactly the same place depending on the number of days you choose
  • Basically the longer the trip, the further you go, the more beautiful the sites you see.
  • The most frequent options:
    • Only Similan Islands (3 day cruise)
    • Similan Islands + Koh Bon and Koh Tachai (4 day cruise)
    • Similan Islands + Koh Bon and Koh Tachai + Islands Surin and Richelieu Rock (5 day cruise)
  • Koh Tachai and Koh Bon really worth it for see manta rays and Richelieu Rock is really essential, certainly the most beautiful site in Thailand !

Logo-plongeur-baroudeur

I you advise to do : Similan Islands + Ko Bon / Ko Tachai + Richelieu Rock. The liveaboard should normally last 5 days.

Tips to Pay Less for Liveaboard in the Similan Islands

croisiere-plongee-liveaboard-ile-similan-hallelujah
Hallelujah
  • By booking at the last minute!
    • No need to book your liveaboard 1 year in advance at Similan Islands!
    • There are so many boats (over 30), that they are rarely all full, even in high season.
    • As always it's a gamble, but if you know which period you are going to, look 1 to 2 months before on liveaboard.com, there are always specials, -10, -20 and up to -30%.
    • For my part, I bring you all the good plans to my knowledge here.
croisiere-plongee-liveaboard-ile-similan-manta-queen-1
Manta Queen 1
  • If you are in long travel mode and have time
    • As always, having time on the spot is the best way to to be able to pay less.
    • There are liveaboards that leave every day, so of course, if the day before they are not full, they can offer you last minute discounts.
    • That's what I did at the time, I went around the centers for 3 days, there was 1 place left on a liveaboard leaving the next day and I managed to reduce the price by 25%!
    • But to do it again, even while on site I would mix with a follow up liveaboard.com, because it's still easier to follow all the offers in real time than going to see all the centers one by one!

HOW TO GO TO SIMILAN ISLANDS

It is quite simple to get to the Similan Islands from Phuket or Bangkok.

Getting to Phuket

MY DIVING REVIEW ON THE SIMILAN ISLANDS

I did the Similan Islands at the end of my 3 month trip to Asia, after Raja Ampat, Komodo and Sipadan for example. My first impression was to be disappointedThailand is not in the The Coral Triangle and it feelsNot at all the same quantity and quality of marine life that I had seen elsewhere in Asia. With the back I would say that the sites of Similan Islands have very interesting topography and that many fish from the Asia zone are represented. Koh Bon and Koh Tachai are worth the trip, especially for manta rays very often present! Finally, Richelieu Rock is a must, a great site, very colorful and varied where you may have the chance to see whale sharks in season. For an experienced diver, I will recommend many other destinations in Indonesia or to Philippines before the Similan Islands. For a new diver, the Similan Islands are without a doubt the best in Thailand!
