Dive off the Beaten Track in Burma's Mergui Archipelago

Why we love it

The thrill of venturing away from the tourist crowds and deep into hundreds of relatively unexplored islands appeals to the adventurous spirit! Myanmar - also known as “Burma” - has been a long-time hermit kingdom and only recently permitted foreign charters to scuba dive their waters. Navigate the Mergui Archipelago and plunge into these magical clear waters with incredible macro life, swim-throughs, and tunnels. Spend your surface interval feeling like Robinson Crusoe on empty white-sand beaches.


Committed to the health of Myanmar’s waters, they work with local and international organizations to protect the area. In 2019, they have organized a cruise to remove ghosts nets with the founders of Myanmar Ocean Project and Ocean Quest Global. They adhere to Longitude 181’s International Charter for Responsible Diving.

Who is it for?

Adventurous divers who like a variety of terrain and challenging conditions (i.e. “strong currents”). Most sites are suitable for deep dives. Other activities include kayaking, island exploration, eating great food(!), and chilling-out in between dives!

Prices and Dates

In the more expensive trip, you’ll dive on a larger variety of sites as you go further north to Torres island, Princept, Tower Rock and The Sisters.

Visas, flights, and more!

Visa Requirements

For Thailand

  • Passport must be valid for at least 6 months from the date of arrival

  • As of August 2017, citizens of France, USA, Japan, Canada, UK, Germany, Switzerland, Sweden, Spain and many other countries do not need a visa for stay of less than 30 days

  • Remember, the boat leaves Thailand and returns again - “resetting” the clock on your Thai visa

  • Verify your entry requirements from the Ministry of Foreign Affairs of the Kingdom of Thailand

For Myanmar (Burma)

You have two options, depending on where you want to finish your trip:

  1. Return to Thailand: In this case, the dive operator will handle your visa entry which is only valid for the Mergui Archipelago. They will handle the interaction with the Burmese immigration, but you’ll need to supply the following:

    • in US dollar bills
    • One recent passport-sized photo (no specific dimensions)
    • Passport
    • The diving fee mentioned above also with US dollar bills
  2. Remain in Myanmar: In this case, you’ll wave goodbye to crew and fellow divers in Kawthoung, the port-side city on the Burmese side before everyone to Ranong. You’ll still need to pay the diving fee, but instead of the Mergui-only visa mentioned above, you’ll apply for an eVisa beforehand which grants entry to visit other places in Burma.

NOTE: Be sure to bring clean, new, unmarked, unfolded, and undamaged US currency
