TreeHouse Villas Koh Yao — treehouse villas in the forest by Phang Nga Bay, adults-only on Koh Yao Noi
Koh Yao Noi sits in the middle of Phang Nga Bay, between Phuket and Krabi — a still-quiet island of Muslim fishing communities, rubber plantations and real local life, with no busy nightlife. TreeHouse Villas Koh Yao is an adults-only (16+) eco-luxury resort on the island's northern tip. The draw is its two-storey treehouse villas set in the forest, reached across a suspension bridge, each with its own private pool. There's a 400-metre private beach facing Phang Nga Bay. From approx. ฿13,000/night. Scored 9.3 from 417 Booking.com reviews, ranked #3 of 15 hotels on Koh Yao Noi on TripAdvisor.
First, it helps to understand the island itself. Koh Yao Noi sits in the middle of Phang Nga Bay, between Phuket and Krabi, and it has held on to its quiet — Muslim fishing communities, rubber plantations, rice fields and real local life, with no busy walking streets and no bars or clubs at night. In keeping with local Muslim custom, some places outside the resort don't serve alcohol. An island like this suits travellers here to rest, honeymooners, or anyone truly wanting to escape the crowds, far more than anyone chasing a party. And TreeHouse Villas Koh Yao sits on the northernmost tip of the island, quieter and more private still.
What sets this place apart from the usual resort is its treehouse villas — two-storey timber loft-style villas raised up in the forest, reached across a private suspension bridge, with the feel of a grown-ups' treehouse. Each one has its own private pool, an open terrace, a swing, and a hammock-shaped bathtub in the bathroom that guests photograph often. The whole resort is adults-only, 16 and over, so the quiet and privacy are all but guaranteed — no children running around the pool — making it ideal for couples who want proper time to themselves.
There are three main room types. It starts with the TreeHouse Villa, a loft villa in the forest with a small plunge pool — the signature stay here. From there you step up to the Beachfront Pool Villa, a single-storey villa with direct beach access and an infinity pool. The largest is the Hilltop Pool Villa, a three-bedroom villa on a rise looking down over the bay, sleeping up to six adults — good for groups of friends or adult families. Guests praise how clean and comfortable the rooms are very often, with Booking sub-scores for cleanliness and comfort sitting around 9.6–9.8.
"Waking up and dropping into the private pool in front of the villa, surrounded by nothing but trees and birdsong, then walking down to the private beach with barely a soul on it, looking at the limestone cliffs out in Phang Nga Bay — that kind of quiet and privacy is hard to find."
Another highlight is the roughly 400-metre private beach on the quiet northern tip of Koh Yao Noi, ringed by limestone cliffs and the little islands scattered across Phang Nga Bay that make up the view. The staff and service are another thing guests mention again and again — warm and genuinely attentive, with the Booking sub-score for staff around 9.6. The in-villa minibar is restocked free every day, and there are free activities like kayaking, yoga and cycling to explore the island.
There's plenty of choice when it comes to eating, with several venues on site. The main restaurant, Roots, serves all day. Al Fresco is Italian, the Seafood Terrace focuses on seafood, and the Sundowners bar is the spot for a drink at sunset. There's a full spa with a steam room and a cold plunge pool to soak in after a treatment. Because the island is quiet and options outside the resort are limited, having several dining venues in one place helps a lot on the days you don't feel like going anywhere.
The honest trade-offs, spelled out plainly. First is getting there. It's fairly remote and reachable only by boat. You'd normally travel by longtail or speedboat from a pier on the Phuket side (around Bang Rong pier / Ao Po / Yacht Haven) or the Krabi side (Thap Lamu / Ao Nang / Tha Len pier), around 30–45 minutes, then a car transfer on the island to the resort. A luxury resort like this usually offers a private speedboat transfer (for an extra fee) so door to door takes about an hour, but you'll want to allow the time and budget for it.
Second is the beach and the tides. The beach in front of the resort is shallow, and at low tide you'll see mudflats / tidal flats in parts, so swimming straight off the resort beach at low tide is barely possible. This is the natural character of Phang Nga Bay and Koh Yao almost everywhere, not a fault unique to this place, but if you're expecting a white-sand beach for swimming all day you may need to adjust your expectations. High tide is when the beach looks its best and you can get in the water.
"The charm is the quiet and the privacy — no kids, no noise, the villas well spaced apart. But you have to know that coming here means truly coming to rest. By evening the island is very quiet, so if you want a party or lots of places to eat out, this isn't it."
The rest of what's worth knowing. Koh Yao Noi has almost no nightlife — it's a quiet Muslim fishing community come evening, and some places outside the resort don't serve alcohol. Some guests note that tours and add-on activities can be pricey, and privacy at a few villas depends on where they sit. In short, TreeHouse Villas is best for couples, honeymooners, or anyone after a slow-life rest in a quiet, private, adults-only setting. If that's your kind of trip, this place delivers a rare experience. Rates start from around ฿13,000/night for a TreeHouse Villa in low/regular season, climbing for the Beachfront and Hilltop Villas.
A tip from reading the reviews: arrange a private boat transfer with the resort ahead of time for the easiest, least time-consuming trip — don't gamble on finding a boat yourself. Check the tide table first so you can plan your beach swims to line up with high tide. And if the budget allows, upgrade to a Beachfront Pool Villa for direct beach access straight from the villa.
