Koh Rong Islands, Cambodia

Set on a hidden archipelago, this is the ultimate island hideaway – exquisitely beautiful, tantalizingly remote and more than a little decadent. Transfer is by speedboat: after half an hour bumping over the big blue, you arrive at a pair of sandfringed islets whose achingly gorgeous villas are built into the forest or suspended on stilts over the water. All have their own plunge pools, decks and sublime sea views. Stroll over sun-bleached walkways to the infinity pool or spa for a massage; snorkel around the reef in search of seahorses; or kayak around the nearby mangroves. Exclusive luxury like this doesn’t come cheap, but the experience is unique.
