The private island resort ranking by what the private island actually gives that the public beach resort does not: the boat transfer (the 15-minute speedboat from the mainland, the specific arrival by water that gives the island as an island rather than a room in a hotel), the absence of the stranger at the adjacent sun lounger, and the specific silence (the generator at night aside) that no coastal resort can replicate. The resorts below are under £1,000/night because the private island resort that costs £4,000/night is a different category — the correct question is which private island gives the private island experience at the price the mid-luxury traveller can justify.

1. Song Saa Private Island, Cambodia — USD 850-1,200 / £669-945 per night
What it is: The two-island resort on the islands of Koh Ouen and Koh Bong in the Koh Rong Archipelago (30km off the Sihanoukville coast, 45 minutes by speedboat) — the 27 overwater, jungle, and beach villas connected by walkways above the water, the house reef accessible from the resort beach, the marine conservation programme (the Song Saa Foundation — the reef restoration and the sea turtle monitoring):
The Song Saa private island gives the specific private island experience (the boat arrival, the resort island visible as the approach, the accommodation that is genuinely above or beside the water) at the price that the Maldives overwater villa charges for the room without the island exclusivity. The Cambodia location (the Gulf of Thailand, the warm water year-round at 27-29°C, the marine life visible from the resort beach) gives the Indian Ocean equivalent at 70% of the Maldives price.
The marine conservation dimension: The Song Saa Foundation’s work is visible — the coral frames in the lagoon, the turtle nesting site markers on the beach, the marine biologist who leads the morning reef snorkel. The resort’s conservation programme is the correct counterpart to the luxury — the private island that uses its control of the surrounding marine environment for the environment’s benefit.
2. NIHI Sumba, Indonesia — USD 700-1,400 / £551-1,102 per night
What it is: The resort on the Sumba Island (East Nusa Tenggara province — the island east of Bali, 1 hour by small aircraft from Bali’s Ngurah Rai Airport): the 27 villas on the Nihiwatu beach (the West Sumba coast, the left-hand surf break that has been consistently rated one of the top 10 surf breaks in the world), the Sumba Foundation (the foundation that NIHI operates to fund the malaria eradication, the school, and the clean water programmes for the surrounding Sumba villages):
The NIHI Sumba private island proposition (it is technically not an island — it is a coastal resort on a larger island, but the 567-hectare estate with the private beach and the private surf break gives the private island experience without the boat transfer): the surf included in the resort fee for the resort’s own guests, the non-surf guest package (the fishing, the horse riding, the village visit, the spa).
The Sumba horse (the Sandlewood horse — the breed native to Sumba, the specific Sumba cultural tradition visible in the pasola (the annual spear-throwing horse battle ceremony, February-March, the most dramatic single cultural event in Indonesia)):
3. Petit St. Vincent, Grenadines — USD 800-1,500 / £630-1,181 per night
What it is: The 115-acre private island in the Southern Grenadines (the island group between St. Vincent and Grenada — 25 minutes by chartered aircraft from Barbados or St. Vincent): the 22 cottages on the island, the British-owned resort that has operated since 1966, the flag communication system (the yellow flag raised above the cottage requests service; no in-room phone and no internet in the cottage — the specific PSV quality of the enforced disconnection):
The yellow flag system: the specific Petit St. Vincent feature — the reed basket delivery system (the staff deliver the meals, the drinks, the requests by the reed basket lowered and raised on the cottage terrace), the absence of the phone giving the specific Caribbean private island pace. The guests who find the absence of the phone intolerable leave by the end of Day 1. The guests who remain find it the most restoring holiday they have had in years.
4. North Island, Seychelles — USD 3,000-5,000 / £2,362-3,937 per night (above budget, for reference)
The North Island Seychelles gives the private island experience at a price that the context of this guide explicitly excludes but that the Seychelles private island category requires as the reference point — the 11 villas, the black-turtle nesting beach, the giant tortoise visible from the villa. Listed to give the correct category comparison rather than as a recommendation within the guide’s price ceiling.
