Quảng Nam is the Vietnamese province around Hoi An, home to the My Son Sanctuary — the brick temple complex of the Champa kingdom — and a countryside of rice fields and pottery villages.
February to April, at the end of the dry season and before the summer heat — the valley is green and the site is comfortable to walk.
Eat cao lầu or white rose dumplings back in Hoi An — both are dishes claimed specifically by this province and difficult to find made properly anywhere else.
Base yourself in Hoi An and treat My Son as a half-day, rather than staying out near the ruins where there is very little.
Go at opening, around 6am if you can manage it. The main tower group sits in a hollow with no shade, and by mid-morning it is both hot and crowded with tour groups from Hoi An.
