We went to Doi Inthanon, Karen Coffee Village, Wachiratan Waterfall, Doi Suthep night view, etc. on a 12-hour course including a van + English-speaking guide. It was really convenient to be able to freely adjust your schedule in a spacious van. Our guide, Art, worked really hard to explain things, was extremely kind, and I could feel that he was paying attention to any inconveniences the group might experience. The driver was also nice (cute lol). The Thai food I ate at a street restaurant somewhere in Doi Inthanon (Art helped me with everything from ordering, confirming the order, and checking the bill) was also delicious!!
