Similan Islands Liveaboard Diving Highlights
World-class diving, white sandy beaches on uninhabited islands, and crystal clear waters that stretch as far as your eyes can see. If you think that the Similan Islands are beautiful, wait until you start exploring underwater.
Similan National Park is made up of nine islands, all of which are referred to by their number rather than their name. Together with these nine islands, other nearby dive sites are the ones in Surin Island which encompass the islands of Koh Bon, Koh Tachai, and the famous Richelieu Rock.
In total, there are over 25 different dive sites to choose from.
As you can imagine, a place like this is rich in marine life. During your dives here, expect to see lots of sharks (reef and leopard), turtles, manta rays, giant groupers, and barracudas.
Elephant Head or (Hin Pusar) is known to be one of the best dive spots within this area due to its intricate maze-like rocks composed of swim-throughs, channels, and gorges reaching depths of over 40 meters. It is really something else and is pretty out of this world!
Other notable sites within the area are Christmas Point and Fantasea Reef.
Similan Islands Diving: What You Need to Know
Best Time to Go Diving in the Similan Islands
Although diving in Thailand happens all year round, the liveaboard season in Thailand runs from November to May.
The best time of the year to dive is in March as the Andaman Sea is at its calmest, with super clear visibility ranging from 25 to 40 meters.
Towards the end of February, the currents get stronger which increases your chances of seeing large marine creatures like manta rays and sharks. If you’re keen on seeing whale sharks, the best time to go is between February to May.
Similan Islands Diving Safety
Generally speaking, the Similan Islands are tide-dependent — if you time your trip during that of a full or new moon, you will most likely face strong currents.
You can find a wide variety of dives from sloping coral reefs to rocky gorges. Some dives are classed as challenging due to the depths and currents.
One key piece of advice is to trust your divemasters and listen to their advice. They have been navigating these seas and are all experienced in reading the changes in the water patterns.
A good practice is to ensure that you always have a neon dive flag or collapsible pole stowed in your BC pocket in case of the current sweeps you astray. Reef hooks and gloves are also advisable due to the strong currents.
For peace of mind during your diving adventures, we recommend having dive insurance in case of any medical emergencies.
Best Diving Itineraries in the Similan Islands
Short Similan Islands Liveaboard Trips
No matter what kind of diving experience you’re looking for, you’re sure to find it in the Similan Islands. With so many sites to choose from, with varying difficulties, it’s no wonder this is considered the best place to scuba dive in Thailand.
Most liveaboards in the Similan Islands offer itineraries ranging from two to five nights.
On trips that are four to five nights, divers often spend the first two days diving around the Similan Islands, and followed by diving around Richelieu Rock and Surin Island in the remaining days. This way, divers are able to experience the best of the region without having to pick and choose where to go.
On a typical short liveaboard trip in the Similan Islands, you can expect to dive three times a day, with a possible night dive as well.
Short trips to the Similan Islands are great for a quick diving getaway, or if you want to beef up your diving skills before going on a longer liveaboard trip. Short trips also tend to be reasonably priced (depending on the boat you choose), making them a great budget option when you want to take a diving vacation.
Extended Similan Islands Liveaboard Trips
There are select boats that offer longer trips around the Similan Islands lasting a week, give or take. These trips take you to the best of the Similan Islands but also give divers the opportunity to explore the waters of Myanmar.
Although Myanmar isn’t a part of the Similan Islands, taking a longer trip will allow you to kill two birds with one stone and essentially take two trips in one. This is special because liveaboards typically stick to one destination, rather than two.
On a week-long trip, you’ll have a hefty mix of reef and wreck dives, with up to four dives every day. Extended trips are generally best for more advanced divers as you’ll visit deeper sites with stronger currents.
Best Dive Sites Around the Similan Islands
Elephant Head Rock
Elephant Head is definitely one of the best dive sites in the Similan Islands.
It is essentially a maze made from giant boulders. It’s called Elephant Head because one of these giant boulders looks like an elephant’s head. Original, right?
Navigate through different swim-throughs, caves and arches while searching for the mystical creatures that live here. Be sure to watch out for the strong currents!
Located south of Island No. 8, you can expect to run into different species of sharks like blacktips, whitetips and leopard sharks. Swim around with barracuda and giant trevallies while discovering all that Elephant Head has to offer.
Christmas Point is another site made up of underwater boulders that are surrounded by rich corals and spectacular marine life. It’s just northwest of Island No. 9, and provides divers with tons of little swim-throughs and small crevices to explore.
If you’re looking for leopard sharks, this is the place to dive as they make frequent appearances. You may spot the occasional black and white tip reef sharks, if you’re lucky. At Christmas Point, you’ll also find tons of large fish like barracuda, tunas and Napoleon wrasse.
Visibility is great at this site, but it’s quite deep and currents can be strong so it’s best suited for more experienced divers.
East of Eden
East of Eden gets its name for a food reason. This site provides divers with glorious reefs and the most variety of marine life of any dive site in the area.
There is so much to see at this site that it’s considered to be an aquarium dive as you’ll be swimming among countless different species, with something new at every turn.
The current at this site is gentle, and provides divers with a slow drift dive. Turtles are commonly spotted in the shallow reef top and sharks even swim around the area!
If you’re diving in Similan, East of Eden should not be missed.
Beacon Point / Reef
This site is a great mix of reef and wreck, giving divers the best of both worlds.
Beacon Point is located near the eastern side of Island No. 8, which is a rocky area filled with boulders buried deep underwater. “Atlantis-X,” a ship that sunk in 2002, is a landmark for Beacon Point and provides great shipwreck exploring for divers.
Besides the wreck, you’ll find lush corals and tons of different reef fish which have made this area home. During your dive, you’ll see angelfish, butterflyfish, pufferfish, triggerfish and moray eels.
From surface level, Richelieu Rock appears to be a lone pinnacle, but once underwater it turns into a horseshoe shape grouping of rocks, overhangs, small caves.
Although it’s located northeast of the Similan Islands, it’s still considered to be one of the most popular dive sites in Thailand, as well as in all of Asia!
As this area is the only place of shelter between Surin Islands and the mainland, marine life is abundant and you’re sure to run into all types of creatures and soft corals while exploring.
If you’re lucky, you may catch sight of a mating octopus among the seahorses, pelagic fish, and big schools of fish. You may also spot a whale shark and the occasional manta ray! Don’t forget your camera because this is one of the best places for macro photography.
Richelieu Rock is a huge area that is impossible to explore in only one dive. Many liveaboards frequent this site, and give divers at least two dives to be able to see as much as possible before moving on to the next location.
How to Get to the Similan Islands
To get to the Similan Islands, you’ll have to fly into Thailand.
Generally speaking, most Similan Islands liveaboards depart from either Chalong Pier in Phuket, Phang-Nga Province, or Thap Lamu Pier in Khao Lak. Some airlines fly directly into Phuket while others may require you to take a connecting flight from Bangkok.
We often use Liveaboard.com to check prices or find last-minute deals. They have a cheapest price guarantee which is pretty awesome! If you’re looking for where to stay in Phuket, you can check out our guide for a few of our personal recommendations.
Choosing which liveaboard to go with can be a daunting task especially since there are so many options to choose from. There are liveaboards that do 1-night tours while others extend them up to 6 nights. It will all boil down to your budget and what type of experience you are after.
One last thing: make sure to read the fine print as most of the liveaboards have external fees such as National Park tariffs and equipment rental. Make sure you consider those when budgeting and deciding which a liveaboard to go with.
