Before anyone is married on Koh Krabey, the island has been counted. Six Senses reports a biodiversity study that recorded 51 species of bird and the endangered Indochinese silvered langur, and a marine survey, made with an independent biologist, that found more than 30 species of fish and 11 genera of coral around the shore. A wedding here takes over the whole island, which Six Senses gives as 12 hectares in the Gulf of Thailand, five kilometres off Ream National Park.
A wedding on the island
A full island buyout, listed here for up to 100 guests from $12,000, gives a wedding party all 40 pool villas, both restaurants and the spa, with no other guests on the island. Ceremonies are listed on the western beach as the sun sets over the Gulf, on the overwater deck, or in clearings among the rocks and jungle, and the listed ways to dine are boardwalk dinners and beach feasts.
Six Senses itself lists weddings alongside milestone celebrations and private retreats, and describes its approach as emotional hospitality with personal attention, adding that seasonal pan-Asian dining and adventure experiences can be woven into each day. Guests stay in the villas, which are free-standing, set among the trees and each have a private pool and sundeck. They run from the one bedroom Ocean Pool Villa, at 77 square metres, to the three bedroom Beach Retreat, at 310 square metres, which Six Senses says sleeps up to eight. The two-villa Beach Retreat, at 190 square metres, is described as suiting families or couples travelling together, and every villa comes with a personal host the resort calls a Guest Experience Maker. Each villa has its own sundeck for dining outdoors. A doctor is on call and the hosts speak several languages, which the resort lists among its guest services.
The resort opened in early 2019: a hospitality trade announcement dated 25 March of that year reported its first guests, and described buildings with green living roofs and the villas’ infinity-edge plunge pools.
The table and the farm behind it
Six Senses describes Cambodian cooking as drawing on familiar South-East Asian staples, with more herbs and fewer spices, and says its restaurants offer both traditional Khmer dishes and its own seasonal interpretation. AHA serves international and pan-Asian dishes all day beside the pool, Tree cooks Khmer and South-East Asian food with seafood as its speciality, and Sunset Bar is a split-level bar for sunset drinks, an ice cream parlour beside the main pool serves housemade gelato and sorbet, and in-villa dining runs from breakfast until evening with dishes from all the restaurants. Much of the produce comes from an organic farm of 3,700 square metres on the mainland, from the chef’s island garden and from a farm the resort calls Happy Farmhouse; Six Senses says the mainland farm produces much of its farm-to-fork dinners and its spa ingredients.
Guests who want to see the source can cross to a Khmer farmhouse on the mainland, where geese, chickens and a pig roam freely and vegetables are cooked over an open fire, or join a Khmer cooking class on the island.
The island, counted
Six Senses describes the island as remote enough yet not cut off from a country rich in culture and history, and it sits near a protected coast. Ream National Park, created in 1993, protects mangrove, seagrass, evergreen forest, beaches and coral reef on the coast of Preah Sihanouk province, about 18 kilometres from the city of Sihanoukville. Koh Krabey lies offshore of it, and the bird study, by Fishing Cat Ecological Enterprise, names hornbills, Yellow-vented Bulbuls, Green Imperial-Pigeons and Pacific Reef-Herons among its 51 species. For guests the findings become an activity: the Island Wildlife Walk crosses the Earth Lab and the island’s gardens, with a chance of seeing silver langurs, water monitors and more than 50 species of bird.
Below the waterline the marine survey lists rabbitfish, emperor, sweetlips, parrotfish and grouper, with giant clam among the invertebrates. Guests can snorkel over the reef, or take a night swim among glowing plankton on an outing the resort calls Illuminating Plankton Gazing.
The Earth Lab is the resort’s centre for environmental education and zero waste, where waste materials are upcycled into new products, and Six Senses reports that 15,719 kilograms of operational waste were diverted from landfill in 2025. On the mainland the resort works with AllKids, an NGO registered in Cambodia, and with Ream Primary School, where it gave teachers 30 hours of digital skills training and installed a 5,000 litre water tank with a solar pump. It reports that 1,485 community members gained improved access to education in 2025.
The spa and the days around the wedding
The Six Senses Spa covers 2,000 square metres, takes its inspiration from the sacred Kbal Spean River, has seven treatment rooms and opens from nine in the morning to nine at night. A wellness screening is used to personalise treatments and longer programmes, and the spa lists visiting practitioners who come to the island. In the Khmer Kru Thnam massage, guests choose the local herbs that are wrapped in muslin and tied into balls, and the Khmer Salt and Herb Scrub starts at the Alchemy Bar, where a guest blends Kampot sea salt with herbs and essential oils. Dreamcatcher, a sound wave bath followed by a foot and scalp massage, sends guests away with a sleep balm to apply on pulse points.
Beyond the island, the resort arranges a castaway picnic on Koh Ta Kiev, kayaking in Ream’s mangrove river and a visit to Ream Pagoda for a monk’s blessing. It also lists Ream National Park itself and the Kbal Chhay Waterfalls as places to visit on the mainland. The experiences page also lists a sky observatory, an ocean boardwalk and a private sand beach among the island’s leisure facilities. Children are looked after at The Nest Kid’s Club, which the 2019 opening announcement describes as for ages 4 to 12.
Planning your wedding
Guests land at Sihanouk International Airport, where the resort lists meet and greet arrival assistance and land and water transfers between the airport, its mainland jetty and the island. The resort’s how-to-get-there page also has a visa requirements section, which matters for an international guest list. The 2019 opening announcement puts the mainland reception about ten minutes from the airport by road, followed by a boat crossing of about 15 minutes.
Six Senses calls Cambodia a year round destination with a wet and a dry season, and its when-to-visit page divides the year into November to February, March to May and June to October without recommending a period for weddings. Three questions need an answer in writing before a date is chosen: the seated capacity of each setting, the arrangements for a legally recognised ceremony in Cambodia, and the terms behind the listed hire price.
The island suits couples who want to take a small, remote place entirely for themselves and who care about the coast and the farm behind the food.
