Garrya Tongsai Bay — A Private Bay and Cottages Built Around the Trees, Samui's First 5-Star Resort
If you're after a Samui stay that isn't a wall of identical beachfront blocks — but instead low cottages scattered across a whole wooded hillside, each facing its own private bay — this is the one. Garrya Tongsai Bay Samui, originally The Tongsai Bay, opened in 1987 as the first 5-star resort on Koh Samui. The owner insisted that not a single tree be felled to build a room, so the 28-acre site is still genuine jungle with more than 67 bird species. What guests come back for again and again: a semi-open bathroom with an outdoor bathtub looking straight out to sea, and a kind of quiet you simply don't get along Samui's main beaches.
The Tongsai Bay story starts in 1985, when Khun Akorn Hoontrakul first saw this bay from the water and called it love at first sight. Seven days later he bought the land, then slept on the beach for three months working out where each cottage could go without cutting down a tree. The resort opened in 1987 as Samui's first 5-star property, and in 2022 it was rebranded under Garrya, the wellness-focused brand of Banyan Group. The original heart is still very much intact — 28 acres of real jungle, 82 cottages spread across the hillside rather than stacked into view-blocking towers.
The rooms people talk about most are the Seafront and Seaview suites and the pool villas. Almost every unit has a terrace with a daybed angled at the water, and the genuine signature here is the semi-open bathroom with a freestanding tub out in the open air — you soak and watch the sea at the same time. Suites start around 67–72 sqm and the largest villas run past 380 sqm. The all-timber interiors feel warm and house-like, closer to a holiday home than a cool, clinical hotel room — which is exactly why regulars are loyal to it.
One guest recalls: "Opened the door in the morning to nothing but birdsong and the sea, then soaked in the outdoor tub at sunrise — three days here and they barely left the property."
The food holds its own against the view. There are several outlets on-site — Rhoy Rhoy for Thai cooking, Fish Tales for seafood, EVOL, and the Po Lad Beach Bar & Bistro down on the sand. Breakfast is a highlight for many guests, cooked fresh to order rather than piled onto a giant buffet, and there are rotating beach BBQ nights and Thai tapas evenings. One honest caveat: because the resort sits in a fairly enclosed bay, heading out to eat elsewhere means a drive, so most guests end up dining in — and the prices are squarely 5-star resort level.
The 8LEMENTS Spa is the resort's own, leaning on Thai massage and herbal baths. Activities run from morning jungle walks on the resort's own trails to Thai cooking classes, kayaking, snorkelling the reef off the beach, and yoga, and there's a kids' club that several families say their children enjoyed more than expected. The thing to be ready for is the terrain — the property is built on a hill, so there's a lot of going up and down and plenty of steps between rooms and the beach or restaurants. Buggies shuttle you around, though at busy times you may wait a little.
The feedback from real reviews lines up consistently. Tripadvisor sits at roughly 4.8/5 from over 3,500 reviews, and the booking platforms rate it highly too. The strongest praise goes to staff who look after you like old acquaintances (many have worked here for decades), the privacy, and the quiet beach. The honest gripes: some rooms show their age given the resort dates from 1987 (clean, and progressively renovated, but classic in style), the natural humidity and the odd insect that comes with a jungle resort, and a few items priced on the high side — all worth knowing before you go.
On price, a Seaview Suite starts around ฿9,000–12,000/night in normal periods, with pool villas opening considerably higher, and high season (December–February) clearly pushing rates up. Against comparable private-beach resorts on Samui that's fair value, because you're getting an entire private bay, a genuinely quiet beach, and rooms larger than most standard beachfront hotels. As always, compare Agoda, Booking and Trip.com before you commit — the gap between platforms is real.
The bottom line: Garrya Tongsai Bay suits couples and families who want a quiet, private, nature-immersed resort rather than the buzz of Chaweng. If you like waking to birdsong, soaking in an open-air tub over the sea, and you don't mind steps or a more classic room style, it delivers an experience that newer resorts find very hard to copy. If you want a sharply modern room and a flat, easy walk to the sand, it's worth thinking twice.

- 💡If steps are difficult, or you're with elderly guests or small children — request a room near the beach or lobby and use the buggy service → the site is a hillside, so the best-view rooms sit high up and mean a climb or a wait for a ride
- 💡If you need a brand-new room — the resort opened in 1987 and some rooms show their age · ask for a recently renovated room or villa, or pick a Pool Villa, which tends to be in better shape → you won't be caught out by the classic style
- 💡If you're wary of on-site spend adding up — the bay is enclosed and eating out means a drive → plan how many meals you'll take at the resort, and check whether your rate already includes breakfast when booking
