If you've come to Phuket to escape and relax, there's no better way to accomplish your goal than to visit one of Phuket's spas. Even the smallest resort now offers full spa services (of varying quality) and you can find good, affordable massage along any beach and in storefronts in the main tourist areas.
For luxury treatments, the most famous and exclusive facility here is The Spa at the Banyan Tree Phuket (see its listing earlier). In secluded garden pavilions you'll be treated regally and may choose from many types of massage, body and facial treatments or health and beauty programs. To make reservations call tel. 07632-4374 (ww.lagunaphuket.com/spa). Expect to pay for the luxury -- figure at least 2,000B ($49) per individual treatment.
Another high-end resort in the furthest southeast of the island, Evason, makes for a great day-spa experience. They are a full-featured five-star with all the trimmings and their spa is renowned (similar to Banyan Tree's prices). They're at 100 Vised Rd. Rawai Beach, Phuket 83130 (tel. 07638-1010; fax 07638-1018; www.sixsenses.com).
Let's Relax is a more affordable little day-spa in and among many similar services (some a bit dodgy really but this one is ok) just off of Patong (Rat-u-thit Rd.; tel. 07634-0913). One hour Thai massage begins at 350B ($8.50).
