The Moei River originates in Phop Phra District, Tak Province. Its most distinctive geographical feature is its northward flow, passing through Mae Sot, Mae Ramat, and Tha Song Yang districts before joining the Salween River in Mae Hong Son Province.

One of the most remarkable characteristics of the Moei River is its reverse flow direction, which contrasts with most rivers in Thailand that typically flow from north to south. This unique feature makes the river well known from a geographical perspective.

The area at the foot of the Thai–Myanmar Friendship Bridge serves as a major border trade hub and is home to Rim Moei Market. The market offers a variety of local products from both Thailand and Myanmar, such as dried bamboo shoots, leather goods, gemstones from Myanmar, and affordable general merchandise.

The Moei River also acts as a long-standing natural boundary and transportation route, closely linking the livelihoods, trade, and cultural exchange of communities on both sides of the Thai–Myanmar border.

Travel Tips

• Check-in spot: Visitors often take photos at the “Westernmost Point at Rim Moei,” marking the westernmost point of Thailand.

• Border crossing: Travelers wishing to cross to Myanmar (Myawaddy) can apply for a temporary border pass at the immigration office near the Friendship Bridge (please check current border opening schedules in advance).

• Season: During the dry season, water levels drop significantly, revealing sandbanks in the river and offering clear views of daily life along both riverbanks.

• Preparation: Bring cash for shopping at the market, and visit in the morning or late afternoon to avoid extreme heat.
