Similan & North Andaman in pictures
Swipe through islands, reefs and marine life. Regional diving scenes are shown; wildlife sightings vary.
The Similan Islands.
Northwest of Phuket in Thailand’s Andaman Sea, the Similan Islands are a group of nine islands at the heart of a marine national park established in 1982. Above the surface, forested hills meet white-sand beaches, turquoise bays and granite shorelines. Below, colourful reefs and dramatic underwater landscapes make the islands a celebrated diving destination.
A rich underwater world.
Soft and hard corals, large sea fans and schools of tropical fish bring color and movement to the reefs. Turtles, barracuda and trevally are among the marine life divers may encounter, while leopard sharks and eagle rays are also possible sightings. Longer North Andaman routes may extend to Koh Bon, Koh Tachai and Richelieu Rock, offering the chance to encounter manta rays or whale sharks. Every sighting is part of the wild ocean and cannot be guaranteed.
Warm water. Seasonal diving.
Water temperatures are generally around 27–29°C, and clear conditions can bring visibility of 30 meters or more. The diving season typically runs from mid-October to mid-May. During the monsoon closure, the park rests from tourism, helping protect its marine environment. Opening dates, visibility, currents and sea conditions vary, so each trip follows current park guidance and local conditions.
Your first liveaboard—or your next.
With a choice of sheltered reefs and more exposed dive sites, the region appeals to divers with different levels of experience. Conditions and entry requirements vary by site and itinerary; we will help you choose a trip that suits your certification and confidence. A liveaboard lets you spend more time at sea, enjoy several dives a day and relax between dives without returning to shore.
How to compare Similan liveaboards
Compare the complete trip, not only its starting price. Use the boat cards above to open each vessel’s cabin photos, departure dates and itinerary, then check the costs and requirements for your selected sailing.
Dates and route
Check embarkation and disembarkation dates, nights on board, diving days and planned dives separately. Route names alone do not tell you the complete schedule.
Cabin and comfort
Compare bed configuration, deck location and bathroom arrangements. Check whether the quoted rate is per guest, shared occupancy or a whole-cabin price.
Complete trip cost
Compare the cabin fare with compulsory fees and the extras you need. A lower starting fare does not always mean a lower overall cost.
Before you book a Similan liveaboard
Does a five-day trip mean five diving days?
Not necessarily. Embarkation and disembarkation arrangements vary by boat. Compare days, nights, diving days and planned dives on the selected itinerary; do not convert one into another.
Are cabin prices per person or per room?
Read the unit shown beside the price. Some fares assume shared occupancy or two guests booking together. Single use, non-diver rates and actual cabin allocation must be checked for that sailing.
Which extra costs should I check?
Check national park or port fees, compulsory service fees, required insurance and any applicable taxes or fuel charges. Equipment, Nitrox, special cylinders and drinks may cost extra. Each boat has its own inclusions and conditions.
Is there an extra fee for paying by credit card?
Next Dive adds 3% to the amount paid to us by credit card. This payment-method fee is separate from the boat fare and onboard charges; confirm the settlement currency and final quote before payment.
Do I need AOW or a minimum number of logged dives?
Requirements depend on the operator and route. Check accepted certification, logged dives and any refresher or private-guide requirement for your sailing before booking; one boat’s rule does not apply to every boat.
Does choosing dates or a cabin reserve my place?
A selection or booking request is not a reserved bed. Space, cabin allocation and the final quote require confirmation. Check the applicable deposit and cancellation terms before accepting the booking.
Check availability.
Tell us your dates, group size and cabin preference. We will confirm availability and send your quotation.
This is an enquiry request. Your booking is confirmed only after we agree the details with you.
