Why you wouldThe good part

1056 curves over 184.9 kilometres. 110 of them hairpins. On a road this tight engine size stops mattering and line choice starts, which is why a 110cc step-through is as absorbing here as anything with four times the power. You are never not doing something.

The riding is the obvious pleasure and it is not the biggest one. What the circuit actually gives you is a rhythm: you are somewhere different every evening, the days are short enough to stop constantly, and there is something worth stopping for roughly every twenty minutes. Nobody rides this loop fast twice.

The province is quiet in a way that is hard to find. Mae Hong Son has the lowest population density of any province in Thailand — twenty-two people per square kilometre across nearly thirteen thousand of them. On the long southern leg you can ride for half an hour and meet four vehicles.

And the thing nobody puts in the itinerary: the ten minutes after you stop. You get off, the engine ticks as it cools, your hearing comes back, and whatever you climbed for is just sitting there. That happens six or seven times a day on this road. It is the whole thing.

06:00 The morning market. Curry in a bag, sticky rice, coffee. It is packing up by nine. 08:00 Ride. The first two hours are the clearest air and the emptiest road of the day. 10:00 The stall at the top of the climb. Twenty minutes, a bench, a valley. 12:00 Noodles, wherever you are. Khao soi if it has not gone; nam ngiao if it has. 14:00 Stop riding. The afternoon is for the town you landed in. 16:00 Hot water on the forearms, or a temple with nobody in it, or a hammock. 18:00 Whatever the town does in the evening. In Mae Hong Son that is two lit temples reflected in a pond.
