Ranong Is Thirty Minutes From Myanmar and Almost Nobody Has Heard of It
The narrowest point of the Malay peninsula, a border town nobody visits, a cashew island offshore and the gate to liveaboard diving. Why I went and what I found.
Ranong is the northernmost province on Thailand's west coast, it shares a border with Myanmar, and it is the narrowest point of the Malay peninsula. Thirty-five thousand people live there. On the day I walked the town I counted four foreign faces and one of them was me.
I had gone for two days and stayed for five.
Last verified 8 October 2026. The Myanmar border and the Ranong to Kawthoung crossing change with political and visa conditions — verify that side of it before you plan a day around it.
Why it is not on anyone's map
Ranong is 568 kilometres from Bangkok, which means it is a full day's drive on the same coast road that everybody already uses to get to Krabi and Phuket. That is the entire reason. Nobody is coming here. The road is good, the scenery is genuinely different, and then there is nothing to queue for.
And Ranong is not tropical in the way people mean by tropical. It is the wettest province in Thailand and it sits in a rain shadow that is actually a rain funnel — the mountains catch everything. It is green in a way the Andaman coast south of Krabi is not, and it is one of the few places on that coast where you can walk around in the wet season and it feels like an accident of geography rather than a disaster.
It is also, in fairness, a border town, and border towns are a specific kind of place: cheap, slightly worn, full of people who make their living from the fact that a line exists, and not at all scenic in the postcard sense.
What you actually come for
Koh Phayam, thirty-five kilometres offshore. It is part of Laem Son National Park and it is the easiest Andaman island in Thailand to reach without flying, which is a low bar that very few islands clear. It is known for cashews and for sand that runs for a very long time. A 30 to 40 minute boat ride from Ranong town costs around 150 to 200 baht, and the bungalows on the far side run a few hundred a night.
Laem Son National Park. Thirty to forty minutes out, 100 baht for foreign visitors, mangroves, quiet beaches and genuinely good birdlife. It is the same park that Koh Phayam belongs to, so if you are crossing for the island you are technically already inside it.
Koh Chang — the other one. No relation to Koh Chang in Trat. This is a tiny, undeveloped island 30 to 40 minutes out that almost nobody visits, which is exactly why you might.
The hot springs, twenty to thirty minutes from town, with public pools for 40 to 100 baht and private ones for 150 to 300, set in jungle.
The diving, which is the real answer
Here is why the liveaboard operators from here are worth knowing about. The Gulf of Ranong is the departure point for three of the best dive sites in Thailand, and two of them are not reachable as a day trip from anywhere else:
Ko Bon has a west wall that drops away to forty metres, with leopard sharks, blue-spotted stingrays and a real chance of manta rays.
Richelieu Rock is the famous one — a single pinnacle seamount in open water, and if it is not the top of the list for the Gulf of Thailand it is not far off it.
Ko Tachai completes the trio.
You cannot day-trip to any of them. They are liveaboard trips only, and that is exactly why the operators are in Ranong rather than in Phuket — the boats leave from here and you sleep on the boat. Several operators run them out of Ranong on a consistent schedule. It is a real, slightly serious way to spend a week, and it is the reason I would send a diver to Ranong rather than a beachcomber.
The Myanmar side, and why you should think hard about it
Across the water is Kawthoung, the southernmost town of Myanmar, formerly Victoria Point, roughly a 30 to 40 minute boat ride from Ranong's fishing port at Saphan Pla.
And this is the part I would be careful about. Travelling into Myanmar requires a Myanmar visa arranged in advance — it is not a border pass situation, and the rules have changed repeatedly and have at times been suspended altogether. You have to formally exit Thailand at Ranong immigration first, you need a boat, and an agent will want paying. A day trip is reported to run roughly 150 to 200 baht for the boat plus a day-entry cost that varies with your visa, and if you are going further into the country you need a proper visa arranged well beforehand.
Verify with Myanmar immigration directly before you book anything. Not a forum, not a tour operator, not a blog including this one. This border has changed its rules more often than almost any other in the region, and the consequences of being wrong are not a fine.
The verdict
Ranong is for the person who has done Krabi and Phuket and found both of them slightly too much of the same thing. It is green, quiet, unpolished and cheap, and the thing that makes it genuinely special — the diving — is something you cannot get anywhere else on that coast.
Give it three nights. Do the border trip or do not, based on what you can verify, and do not let a day tour sell it to you as an adventure. It is not an adventure. It is a small town at the end of the road with three proper dive boats leaving from it, and that is a much better thing.
