Mae Sai District is about 62 kilometers from Chiang Rai Distric, and is Thailand's northern-most district. Mae Sai borders on Myanmar's Tha Khi Lek marked by the Mae Sai River with a bridge spanning both sides. Foreign visitors are allowed to cross over to Tha Khi Lek market by presenting their passports and paying a fee at the Mae Sai immigration checkpoint. In addition, there are tour services to Chiang Tung in Myanmar, which is approximately 160 kilometers north by road.

Wat Phra That Doi Tung (Mae Chan District)

     Wat Phra That Doi Tung is situated on top of Doi Tung Mountain, the highest mountain in Chiang Rai Province with an elevation of approximately 2,000 meters, about 50 kilometers south of Mae Sai town which is near the Myanmar border. The temple can be reached via a 40-kilometer mountain road which meanders along the mountainside. The journey is worthwhile as the panoramic views into Laos and Myanmar at the peak are spectacular.

     Wat Phra That Doi Tung was constructed in the 10th century and was renovated by Chiang Rai's most famous ruler King Mengrai during the 13th century and by the famous Chiang Mai monk, Khru Ba Siwichai, at the turn of the 20th century.

     The temple complex is comprised of twin Lanna style chedis, one of which is said to contain the left collarbone of the Lord Buddha. Throughout the year, the holy relic draws devout Buddhists from all over Thailand, Laos and Myanma.

Doi Mae Salong
     Doi Mae Salong is the site of Santi Khiri village, a community settled by the former Chinese 93rd Division who moved from Myanmar to reside on Thai territory in 1961. The village became well known for its enchanting scenery and tranquil atmosphere. Today it is a major tourist attraction with its small-town ambience, delicious native Chinese dishes, small hotels and guesthouses catering to visitors and tea, coffee and fruit tree plantations. The scenery is especially picturesque in December and January when sakuras are in full bloom. Scattered with many hill tribe villages, Doi Mae Salong is ideal for trekking.

     To reach Doi Mae Salong, take the Chiang Rai-Mae Chan route for 29 kilometers, then turn left and proceed for another 41 kilometers (passing a hot spring). The return trip can be taken on routes nos. 1234 and 1130 which wind through Yao and Akha hill tribe villages. From Doi Mae Salong a road leads to Tha Thon, the starting point for the Kok River cruise, a distance of 45 kilometers. There are hotels and guesthouses to accommodate tourists and a paved road leading to the village.
