Chinese Martyrs' Memorial Museum
A tribute paid to the Kuomintang settlers of Mae Salong, who fought and sacrificed for Thailand. It exhibits the history of their struggle, along with developments of Mae Salong throughout the years. Reached by a well-signed turn-off from the southern road after the market, a short hike or quick motorbike trip.
OTOP Agriculture Centre
This grandly named site — it's actually just a mostly-closed hut, a map of tea plantations in the area, and a thermometer-equipped viewing point — is primarily handy for getting your bearings if you have your own wheels and want to do a round of the many tea plantations around the town.
Phra Boromathat Chedi
A chedi Thai-style stupa built on a hill near Mae Salong village, in honour of the late Princess Mother, Srinagarindra. Next to the chedi is the Princess Mother Hall, a modern, Thai-style pavilion outwardly like a temple in appearance, but not containing any religious objects. There are good views across town and west towards Myanmar from up top. There are two ways up top: on foot, follow signs from the village center up the hill towards the Mae Salong Resort and Wat Santikhiri, and then go up the steep 718-step staircase. If you have your own wheels, there's a winding, steep road that starts from behind the tourist market and curves up from behind, with breathtaking hilly views along the Myanmar border.
Tomb of General Tuan
The mausoleum of Mae Salong's founder and erstwhile drug warlord, Kuomintang General Tuan Xi-Wen. Located at the end of a road beside a tea house with General Tuan's name, up another steep staircase. There's a small museum here, but unfortunately it's all in Chinese. There are some tea houses nearby, and you can enjoy a spectacular view of Mae Salong there.
Wat Santikhiri
A modern, standard-issue Thai temple guarding the approach path to the Phra Boromathat Chedi. The more interesting parts of the temple lies across the street leading to the Mae Salong Resort; peek inside for a nice little Chinese-style pavilion.
