Private Island Experiences in Thailand 2026: From Day Charters to Full Island Buyouts

Thailand's island geography — over 1,400 islands, the majority uninhabited — creates extraordinary opportunities for private island experiences that range from a half-day speedboat charter to a private island resort for an entire week. Day charter private island access: the Andaman coast around Krabi and Trang has dozens of small uninhabited limestone karst islands within 30–90 minutes of the mainland by speedboat. Private speedboat day charters (6–8 passengers) cost 8,000–18,000 THB for a full day; a good captain will know which uninhabited beaches are accessible and which bays have the best snorkelling. Koh Hong (Krabi), Koh Kradan (Trang), and the Phi Phi archipelago offer superb private anchorages. Small private island resorts: Koh Haa Yai (Trang province) — Six Senses Yao Noi is not on its own private island but a close equivalent; extraordinarily exclusive. Koh Mook's Sivalai Beach Resort occupies a private headland on an island accessible by a 10-minute ferry. Song Saa Private Island (Cambodia-adjacent) — technically just over the border but accessed through Thailand's Ko Chang area; the definitive private island resort in the region. Koh Pha-ngan's Haad Yao beach on the northwest coast: accessible by longtail only at high tide, feels private. Full island buyout: several smaller island resorts in the Gulf and Andaman offer full island buyouts for events, weddings, and ultra-private holidays. Prices from $10,000–50,000+ per night for full buyout. Liveaboard yachts: the most flexible private island experience is a liveaboard private yacht charter — position yourself wherever you want in Thai waters. Prices from $1,500/night for a 50-foot sailing yacht to $15,000+/night for a superyacht. The Similan Islands (accessible only by liveaboard during season, November–May) offer some of Thailand's most pristine uninhabited island anchorages.
