Mergui was the name given by the British to the southernmost part of Burma. The Mergui archipelago was off-limits to foreigners until 1997; although it is now open for tourism, access is limited and it remains largely unexplored.
The road to Dawei is open now for foreigners. The bus costs about MYK8,000 and it takes 10 hours for the 200km.
Myanma Airways has daily flights, and Air Bagan has 3 flights per week, from Yangon. Myanma Airways flights (typically once a week) from Mawlamyine and Kawthoung may also be available - check locally at the local Myanma Airways office.
Air KBZ has daily flights during the tourist high season (beginning October to end of April) which fly from Yangon to Kawthoung (and return) stopping in Dawei and Myeik. Prices for the Myeik to Kawthoung leg start at around USD50.
Flights may be cancelled with little or no advance notice, due to lack of bookings, the weather, or any number of other unpredictable circumstances.
Fast ferries run daily to/from Kawthoung (c. 6 hours, USD25-45 for foreigners) and most days to/from Dawei to the north (c. 4 hours, USD20-25 for foreigners). Ferries to Kawthoung depart around 07:30 while ferries to Dawei depart around 10:30 or so.
Five Star Line passenger ships may call here (approximately fortnightly) en route from Kawthoung to Yangon and/or vice-versa. Five Star Line have an office opposite the main piers. Foreigners must pay very high prices (c. USD100+) but the first-class 2-berth cabins are quite comfortable.
On foot, or by motorcycle-taxi or cycle rickshaw.
Longtail boats operate as ferries across the harbour.
There is a food market by the water front in the evening.
There are numerous small establishments with good food.
There are several ultra-basic "guesthouses" in the area around the main piers, a few of which accept foreigners. Often, conditions are grim and prices for foreigners are astronomical.
There are a couple of state run hotels.
There is a very comfortable Western-operated (French) hotel a couple of km out of town on the main road heading north-east; prices here are reasonable.
The Mergui Hotel is a fair distance from the Strand Rd (tuk-tuk drivers will charge up to MYK4000 to get there) but is one of the nicer hotels in town and close to the airport (free shuttle service). It has fast Wi-Fi, a range of satellite channels and perfectly acceptable rooms. Prices start at USD40.
