Answer
Getting to Chiang Rai from Chiang Mai is quite easy, and you have a couple of good options to choose from.
• By bus: Buses leave regularly from the Arcade Bus Station and take about 3-4 hours. The fare is around 200-250 THB, making it an economical choice.
• By minivan: Similar to buses but a bit faster, minivans can get you there in about 3 hours. They're slightly more expensive, around 250-300 THB, depending on the service.
• If you're looking for more comfort, consider hiring a private taxi. This will be more expensive but allows for flexibility in your schedule and stops along the way.
Practical Chiang Mai planning note: Chiang Rai is a separate province and a long day trip can feel rushed. Consider travel time, early departure, mountain-road conditions and whether an overnight stay would make the trip more comfortable. Prices and fares change, so request the current amount before committing.
