Koh Mook Sivalai Beach Resort — Bungalows on a Sand Spit with Beaches on Both Sides
Koh Mook sits off the Trang coast, a quiet island famous for the Emerald Cave and clear water. Koh Mook Sivalai Beach Resort occupies a spot that's hard to match — the white-sand spit at the very tip of the island, with beaches on both sides, so you can walk from your bungalow into the sea almost all the way around. It's a 4-star resort with 60 Thai-style bungalows, private terraces, a pool, and a seafront restaurant. From approx. THB 3,500/night. Score 9.4 from 64 Trip.com reviews, and ranked #2 of 10 hotels on Koh Mook on TripAdvisor.
What guests talk about most is the location on a sand spit reaching out into the sea at the very tip of Koh Mook. It's a narrow ribbon of white sand with beaches on both sides, so you step out of your bungalow and into the water almost all the way around — pick the sunrise side one morning, the sunset side the next. The resort spreads 60 bungalows along the spit; it's a comfortable scale, not a sprawling crowded resort. Plenty of reviews say you simply won't find this kind of setting anywhere else on Koh Mook.
Rooms are Thai-style bungalows and villas from 44 sq.m up. Deluxe Villas sit in the garden inland on the spit; Deluxe Beachfront Villas are in the front row right on the sand; and the Sivalai Suite Villa at 98 sq.m is the largest if you want more room. Every unit has air conditioning, a private terrace with seating, a TV, a minibar and an en-suite bathroom. Guests say the bungalows are roomier than expected and clean for a small-island resort — though some reviews note honestly that a few units feel dated, as the resort has been open for over 20 years.
"Open the bungalow door and there's the white sand and clear water — a few steps and you're swimming. In the evening you watch the sunset off the tip of the spit. So quiet you only hear the waves."
The heart of the place is the beach and the quiet. There's an outdoor pool, a seafront restaurant serving Thai food and fresh seafood, and a buffet breakfast that reviews often praise as better than expected for such a small island. The resort runs boat transfers from the mainland piers and arranges boat trips to the nearby Emerald Cave, Koh Kradan and Koh Cheuk. Staff are a real highlight — guests repeatedly describe them as warm and attentive throughout the stay, though some note that a few staff have limited English.
There are trade-offs worth being upfront about. First, getting there: Koh Mook has no airport and no bridge, so you take a boat from the Kantang or Pak Meng pier and the resort meets you with an onward boat; schedules depend on the tide and the weather. Second, the age of the resort: it's been open a long time, so some bungalows and furnishings feel worn, and a few reviews mention firm beds and faded tiles. And because it sits on a natural beach, sand flies can bite in certain seasons. Scores: 9.4 from 64 Trip.com reviews, 8.7 on Booking.com, and 4.1/5 from over 881 TripAdvisor reviews — ranked #2 of 10 hotels on Koh Mook.
Sivalai isn't for everyone. If you want a brand-new resort, slick modern rooms, or restaurants and nightlife you can walk out to, Koh Mook and this resort aren't that. But if this trip is about white sand, clear water, quiet, and a sand-spit setting with sea on every side — for couples, families, or anyone after a slow-life break on an island that's still uncrowded — it delivers exactly that at an easy-to-reach price. Rates start around THB 3,500/night for a standard bungalow in low season, rising to THB 5,000–7,000+ for front-row beachfront rooms and in high season.
A tip from reading the reviews: if your budget allows, choose a front-row Deluxe Beachfront Villa — you open the door onto the sand, well worth it for making the trip to Koh Mook. Book the boat transfer with the resort in advance and check the boat times against the tide. Bring repellent for sand flies and mosquitoes, since it's a natural beach. And book the Emerald Cave trip early — it's the highlight of Koh Mook and very easy to reach from the resort.
