Frontier Town
Close to Myanmar, Mae Sot is an enticing maverick frontier town where black market timber, gems and everything else are major sources of income. Thais, Burmese, Karen, Chinese and a few Kayah and Hmong constitute the ethnic mix. A bridge across the Moei River links Mae Sot to Myawaddi in Myanmar, although the Burmese military opens and closes it whimsically. The Burmese side sometimes experiences skirmishes between the military and ethnic insurgents, mainly in the dry season. During the April gems fair, Thai and Burmese boxers fight unofficial five-round Muay Thai matches. The location changes yearly: ask the locals where it is.

Refugee Camps
The conflict in Myanmar often causes floods of Karen refugees who swell the camps of Mae La and Mawker on the Thai side of the Moei River. You can donate clothing, medicine and other supplies through No. 4 Guest House at 736 Intharakhiri Road; camp volunteers often spend weekends here and at other guesthouses. Camp security is tight, but volunteers might agree to take you along as an invited guest.

Temple Views
Wat Phra That Doi Din Kiu is a temple out of town on a forested hill, with views of Myanmar and the Moei River. It has a stupa built precariously on a cliff edge. You can also see fantastic scenery at and around Umphang and Thilawsu, about 3-4 hours’ drive from Mae Sot. Both areas have stunning mountains, forests and waterfalls. Treks and rafting are available, taking you through out-of-the-way hill tribe villages.
