For ultimate relaxation, immerse yourself in the spa's Rainforest Experience - a series of scrubs, showers and steam rooms, followed by a dip in the dedicated pool complex.
In Thailand, there exists a piece of furniture that truly defines the national culture's approach to life. It's the "Triangle Pillow." The soft peaked Triangle Pillow sits anywhere on any ground; how you use it, is up to you. Lean back with a book and a cold beer, or lie your head down, close your eyes, and drift away.
Banyan Tree Koh Samui embodies the region perfectly, with a pristine, rock-framed beach and 78 villas, each with private pool (if the huge main pool is just too open for you). White walls are punctuated with sliding glass doors opening to the pool and glass-railed patio.
One of the larger draws here is the Banyan Tree Spa Samui Rainforest, the region's largest Hydrotherapy Spa. Afterwards, chill out some more with a read in the Library, or a little stretch in the Yoga Room.
Banyan Tree Samui also has a taste for good eats. All sorts of good eats, actually: sample authentic Thai at Saffron, International favorites at The Edge, beach barbecue at Sands, and cold bevies at the Lobby Bar and Pool Bar.
Not to worry if you brought little ones, they'll be well attended to at the kids clubs, while you're at the adults club.
