Mae Hong Son (แม่ฮ่องสอน) is a city (pop. 7,000) in Mae Hong Son Province, Northern Thailand.

Walk around the picturesque lake and visit the surrounding wats. Wat Phra That Doi Kong Mu (aka Wat Phai Doi) overlooks the town from the west and offers superb views.

• Ban Rak Thai (Mae Aw). A Kuomintang (KMT) village near the Myanmar border. On your way up (or down), you can stop by Mae Hong Son (Ruam Thai), a picturesque Shan minority village high in the mountains. 
• Pang Ung. Often referred to as Ruam Thai on some signs and maps, is a Shan Minority Village near Mae Hong Son. It should be combined with a trip to Ban Rak Thai. It is a picturesque village of bamboo houses, probably dolled up a bit for the tourist industry. Bamboo grows everywhere, including one stand at least 80 feet tall. There are one or two restaurants. It is unclear what they serve. Shopkeepers and restaurant owners speak some English, but this is not as heavily touristed as one might expect, so communication will be limited if you don’t speak Thai. There are at least two homestays here, and another guesthouse in the town between Pang Ung and the main road. From Mae Hong Song, follow signs for Ban Rak Thai, but at the village of Na Pa Paek, turn left, following the signs for “Pang Ung Reservoir,” or something of the sort. The signs are not exactly consistent, but if it indicates a reservoir, you are going the right direction. It is about 5.5 km from the turn-off, at N19 29.955, E097 54.705. 
• Fish Cave (Thumpla) (Near the village of Huay Pha, about 17 km from Mae Hong Son via Highway 1095). This is a beautiful spot to escape the heat. A water channel that wends its way out of a small submerged cave. What is inside the cave is still unknown, but it astoundingly draws thousands of the “Pluang-Hin” fish into the cave, with only a small number of them coming back out. 
• Pha Sua Waterfall (26 km from Mae Hong Son on the road to Pai). This waterfall consists of six levels and offers some fine walks. This waterfall is about 20 m high and 30 m wide. It is said to be the most beautiful waterfall in Mae Hong Son Province. In rainy season, the cascading water makes the waterfall look like a rolling mat. 
• Thampla-Phasua Waterfall National Park (อุทยานแห่งชาติ ถ้ำปลา – น้ำตกผาเสื่อ). This national park covers more than 488 km of the “Thanon Thongchai” range that separates Thailand from Burma. “Doi Larn” is the highest peak in the area, with an elevation of about 1,918 m.
