Chiang Mai to Chiang Rai is a classic northern Thailand connection — linking Thailand\’s second city with the gateway to the Golden Triangle and the Mekong slow boat into Laos. The journey takes 3–4 hours by bus or minivan through mountain scenery. Most travelers use this route as part of a northern circuit or heading to the Laos border at Chiang Khong.

Option 2: Minivan (Faster, More Frequent)
Shared minivans depart from Chiang Mai Arcade Terminal and from a few spots near the Old City — approximately 3 hours to Chiang Rai, fares ~200–250 THB (~$5–7 USD). Slightly faster than the bus and more flexible departure times. Drop-off options sometimes include Chiang Rai town center guesthouses.
Option 3: Via Tha Ton (Scenic, Full Day)
The scenic detour: bus from Chiang Mai to Tha Ton (~4 hours, ~100 THB), then longtail boat down the Kok River to Chiang Rai (~4 hours, ~500 THB, departs 12:30 daily). The river journey passes through jungle, hill tribe villages, and elephant camps. Total time ~8–9 hours but one of northern Thailand\’s most memorable routes. Only runs in rainy and early dry season when water levels allow.
Continuing to Chiang Khong (For Laos Slow Boat)
If you\’re heading to the Laos border, continue from Chiang Rai to Chiang Khong — approximately 1.5–2 hours by bus or minivan from Chiang Rai Bus Terminal 1, ~80–100 THB. First bus ~07:30 — critical if you want to make the same-day slow boat to Luang Prabang.
