This wellness resort on the Gulf of Thailand was founded in 1995, but it continues to be ahead of the game.

The spa is renowned for its in-house Niranlada Medi-Spa, a separate spa that specialises in aesthetic treatments like microdermabrasion and non-invasive laser procedures.

The spa has added new fitness programs to its formidable list of offerings, and introduced a cutting-edge training chamber that's said to increase the body's ability to burn calories.

In addition to having over 200 spa treatments to choose from, there's a staff of doctors, nutritionists, acupuncturists, physiotherapists and naturopaths on site.
