As far as luxurious private islands go, this one is fairly cheap. Barberyn Island can be found just offshore from the town of Beruwala, on the south-west coast of Sri Lanka, just 35 miles south of the capital of Colombo. On the market with Sotheby's International Realty for $8 million (£5.9m), this pristine stretch of sand is a rare opportunity for someone hoping to snap up a piece of paradise in the Indian Ocean. 

Covering 11 acres, the island has a jetty for easy access to the sea and a breakwater to protect the isle when Mother Nature does her worst. According to the listing, building permits can be obtained with ease and the isle has already been registered as a resort and spa. Since Sri Lanka has very generous planning policies, the island can have a maximum built area of 60% plot coverage, meaning the lucky new owner can get straight to work on constructing their dream home, along with some guest accommodation.

A true slice of heaven, Barberyn Island is adorned with swaying coconut palms, a charming stone lighthouse, enchanting rock pools, idyllic beaches and plenty of lapping waves. Of course, the surrounding azure waters provide ample opportunities for water sports, fishing and wildlife watching – not a bad way to spend your days!

A natural haven of over 12 acres, the island of Ethereal is an untouched paradise a few miles from mainland Greece. The idyllic spot, which has been visited by notable names including Winston Churchill, the Greek Royal Family and rock stars like The Beatles, abounds with ancient olive and cypress trees, as well as a variety of fruit trees yielding pomegranates, apricots and peaches.

Rich in marine wildlife and white-sand beaches, the island has two traditional Greek homes, a church and a boathouse. The main property features four bedrooms, while a bungalow situated on the beach below would make an ideal guest cottage. With its own network of pathways and roads running between the structures, this is a great opportunity to own your own town.

A 15-minute helicopter ride from Athens International Airport, the main dock also allows direct access to the sea if you prefer to sail. With the island helpfully connected to a mainland water supply, all you need to worry about is which beach to sunbathe on next. Who wouldn't want to while away their days gazing at those crystal clear waters?
