Mae Hong Son
The Mae Hong Son loop — 600 kilometres of switchbacks (1,864 bends, locals will tell you) curling through the mountains northwest of Chiang Mai — is the country’s great motorbike road trip and a four-to-six day commitment by car. The midway hippie town of Pai is the obvious overnight, with its sunset canyon walk a 20-minute drive away. Further on, Pang Oung is sometimes called the “Switzerland of Thailand”: a small alpine reservoir ringed by pines that turns pink and misty at dawn. Plan around the season — the cool months (November-February) are best; the rains turn the road slick and the burning months (March-April) wreck the air quality.
