Song Saa Resort, Cambodia
This is one for spa-lovers. Technically this is two islands, but they are linked by a footbridge and the resort is spread over both. You can rent a private villa overlooking the sea, or one tucked away in the jungle, says Jo Foley in The Daily Telegraph.
“Treatment villas and other places of tranquillity” are spread around the resort, rather than being housed in a central spa building. The resort’s ‘head of wellness’ will help you create a tailored programme of treatments. Other activities available include yoga, hiking in the rainforest, or gardening workshops.
• From £795 a night for a one-bedroom jungle villa (Songsaa.com).
North Island, Seychelles
They are decorated in a style described as “haute couture Robinson Crusoe” by one of the co-architects.
“It fuses polished… teak, pine, rosewood and ylang-ylang, thatched roofs, rough granite and a lot of large pebbles – though the villas are not so eco as to eschew air-conditioning.”
• From £2,000 per person per night, all-inclusive (www.north-island.com).
Hell Bay, Bryher
It’s not quite a private island, but it’s probably the nearest you’ll get in the UK. Bryher is the smallest of the five inhabited Isles of Scilly, with a population of around 80. Hell Bay, the only hotel, is “tucked away in a secluded, Atlantic-facing cove”, says Lonely Planet Traveller. The rooms are spread across a range of cottages with “mostly sea views”.
The island itself is a “living paean to an England that probably never existed – wander its lanes and you’ll find hedgerows abundant with wild flowers and the odd honesty box, where a pound will get you a punnet of home-grown strawberries”.
• Rooms from £135 including dinner (www.hellbay.co.uk).
Lake Mälaren, Sweden
There are just four buildings, including a “light, airy” three-bedroom house and a sauna, says Condé Nast Traveller.
The price includes the use of a small boat to get you to and from the mainland.
• It costs from £5,700 for the minimum stay of two weeks (Grandtripsweden.com).
Laucala Island, Fiji
For a more active holiday, try Laucala Island in Fiji, says Condé Nast Traveller. It’s owned by Dietrich Mateschitz, the creator of energy drink Red Bull and owner of two Formula 1 teams, whose “priorities have more to do with sport than with environmental concerns”.
So, the island boasts a golf course, the biggest swimming pool in the South Pacific and nine water craft, “ranging from three jet-skis to a game-fishing pleasure cruiser”. There are just 25 villas, “each with its own pool, dotted around its two and a half miles of coast”, served by 329 staff.
• From £2,995 a night (Laucala.com).
Six Senses, Laamu
“Short of an actual shipwrecking, this is island life at its most isolated – at night, the only sound is the sea, lapping gently at your jetty.” You arrive by speedboat at your own villa, the best of which “straddle the sea”.
The “sun-bleached timber structures” are simple yet grand, “with white curtains billowing around huge picture windows”.
• From £445 (Sixsenses.com).
