After a major revamp, Rarin Jinda Wellness Spa in Chiang Mai (www.rarinjinda.com) is back bigger and better than ever.

Atop the four-story building sit four Thai-style villas for those seeking extreme privacy. However, the traditional decor belies treatments which utilize the most modern onsen and hydrotherapy technologies, while of course classic Thai massage is also on offer.

Packages last anything from 1-4 hours—try the 40-minute Splashy Hydropool Massage (B1,500 for an hour and a half), which sees your whole body massaged by warm jets of water from a series of eight-station shower heads in a big indoor swimming pool.
