Myanmar's Mergui Archipelago: What You Can Actually Access in 2026

Before we write anything else about Mergui, we need to be honest about the situation.

Myanmar has been in a civil conflict since the military coup of February 2021. Most Western governments actively advise against non-essential travel to the country. The tourism industry, including the liveaboard operators who used to cross from Thailand into Mergui, has operated inconsistently and under restrictive conditions for most of the period since.

This piece exists because repeat clients continue to ask about Mergui, and because we'd rather give them an honest answer than either a tourism brochure or a blanket refusal. If Mergui is somewhere you're considering, here's what it was, what it currently is, and what we'd actually recommend.

What Mergui was

The Mergui (or Myeik) Archipelago is roughly 800 islands in the Andaman Sea, stretching north from the Thai-Burmese border along Myanmar's Tanintharyi coast. Closed to foreigners until 1997, it opened gradually over the next two decades as one of the last genuinely unexplored dive destinations on earth. By the mid-2010s, three to four liveaboards regularly crossed from Ranong or Kawthaung into Burmese waters for 7–10 night itineraries.

The diving was pristine by any measure — healthy reefs, schooling pelagic traffic, manta aggregations at specific pinnacles (Black Rock became locally famous), silvertip sharks, grey reefs, and the specific experience of diving ocean that had never been commercially fished in any serious way.

Moken sea gypsies — the indigenous nomadic people of the archipelago — still lived on boats and in stilt-house villages. The whole region had a genuinely untouched quality that's increasingly hard to find.

What changed

The 2021 coup disrupted essentially all international tourism. Liveaboard operations across the Thai-Myanmar border stopped or became intermittent. Some operators attempted to resume operations on reduced schedules as border conditions permitted. Others closed their Mergui routes permanently.

The ongoing conflict has created additional complications:

• Visa and entry conditions for foreign visitors shift without notice
• Dive permit approvals are at the military government's discretion and not consistent
• The ethical question of tourism revenue reaching a military junta is unavoidable — many operators and travellers have concluded they don't want to provide it
• Western travel insurance often excludes Myanmar entirely

As of early 2026, there are operators quietly running limited Mergui itineraries under specific conditions. The trips exist. They are not a straightforward booking.

What we recommend

For almost all clients asking about Mergui right now, we recommend the following:

If you want Andaman Sea diving this year: go to Thailand's Similan and Surin Islands, or consider the Indian Andaman Islands (Havelock, Neil). Both offer comparable reef and pelagic diving without the political complications. Similans in particular have a 20-year head start on the diving tourism infrastructure, at a fraction of the logistical risk. A 7-night Similans liveaboard runs €1,400–€2,400.

If you specifically want "the last frontier" feel: the Solomon Islands is the more honest recommendation for 2026. Genuinely under-visited, politically stable, Pacific Coral Triangle reef quality. See our Solomons guide.

If you want Mergui specifically and nowhere else: we will discuss it with you, including the ethical considerations and practical risks, and we will help you route a trip if you choose to book one. We won't pretend the situation doesn't exist.

When this changes

We'll update this post when Mergui becomes straightforward to book again. The diving itself is still there — the archipelago is, if anything, recovering from the pause in tourism traffic. What needs to resolve is the political and logistical layer around it.

If Mergui is on your long list, the most useful thing you can do right now is pick one of the alternative destinations and come back to Mergui in 2027 or 2028, when the picture may look different.
