How Long Is the Drive to Chiang Rai?

The drive from Chiang Mai to Chiang Rai takes about three hours each way. From Tha Phae Gate to Wat Rong Khun, the White Temple, is 172 km by road; Greenbus, which runs the scheduled coaches, says 3 to 4 hours on Highway 118. On a day tour that means six to eight hours on the road, which is why the day lasts 12 hours or more. MONKEY TRAVEL ASIA’s Chiang Mai: Chiang Rai White, Blue and Red Temples and Karen Tribe, from US$29 on promotion, usually US$49 a person (checked November 2026), breaks the way north with two stops and drives straight back.

The day cost US$34.06 a person without temple tickets and US$41.15 with them on the dates we read (26 November 2026, 20 January and 24 March 2027; checked November 2026).

The distance, end to end

Distances and times from a route planner with free-flowing traffic; real days are slower.

The route planner’s times assume an empty road. Greenbus, on a page dated 9 October 2026, puts the two cities 180 to 185 km apart and its coaches at 3 to 4 hours, “depending on traffic, road conditions, stops, and the selected service” (checked November 2026). Plan on three hours each way in a tour vehicle and you will rarely be wrong.

How a day tour spends its hours

The tour vehicle is the same coach or van all day. What changes from tour to tour is where it stops and how late it gets back.

Times from each tour’s itinerary and notes, checked November 2026.

The temples-only days are back between 7 and 9 PM. Adding the Golden Triangle, on the border north of Chiang Rai, pushes the return to about 10 PM; the Golden Triangle day tour weighs that.

The road itself

Greenbus’s coaches commonly follow Highway 118, through the mountains of northern Thailand. The route includes winding mountain roads, so pack motion-sickness tablets if you need them. Reviewers of MONKEY TRAVEL ASIA’s day on 2 and 6 November 2026 wrote about road works and a rough surface on parts of the way; we found no notice from the road authorities giving their extent or end date.

The morning traffic in Chiang Mai is the other variable. Anyone heading to a meeting point needs to allow for it: nobody can join the coach once it has left.

If the drive is the problem

Three ways round it, each with its own page here:

• Stay the night. Sleeping in Chiang Rai splits the road in two; day tour or overnight compares the options, including tours that drop you in Chiang Rai.
• Your own car. A private driver stops when you want and can end the day in Chiang Rai; see the private day tour.
• Go in the cool months. The road is the same, but cool December mornings make a long day easier than the hazy months of February and March; see the cool season.
