About Chiang Saen
Chiang Saen is an old town on the Mekong, in the north of Chiang Rai province and close to the Golden Triangle. In the past it was a capital of the Lanna kingdom, and that history is still visible in remains of the city wall, temple ruins and restored chedis among the rice fields. The Chiang Saen museum tells the history of the region. By the river there are small restaurants with views of Laos, and you can take a boat trip. A short distance away lies Sop Ruak, where the Ruak flows into the Mekong and three countries meet. Chiang Saen is calmer and more authentic than the best-known tourist places in the north, and it is a lovely area for cycling. Feel free to stay overnight: the evenings by the river are peaceful.
Best time to visit (indicative)
Best from November to February: cool and dry, with chilly mornings in the hills. From February to April smoke and haze from agricultural burning can limit visibility; June to October is the rainy season, green and quiet. Weather varies from year to year; this is a guideline based on the climate.
Getting there
From Chiang Rai by bus or songthaew (about 1 hour, roughly 60 km); your own transport or a bicycle helps for the ruins. Distances and travel times are rounded estimates.
