Six Senses Krabey Island

In a quiet spot on the hillside, the infinity pool comes with top-tier views and if you tire from swimming (or reclining), enjoy a little hydrotherapy at the spa's whirlpool, try a sound bath or luxuriate with a 24-karat gold leaf facial. Enjoy everything from Pan-Asian cuisine on a sunny patio to Khmer seafood specialties at the lovely Tree restaurant. Below a shoal of paper fish, the Sunset Bar provides relaxed cocktails like the Khmer Mule on the day bed or hammock of your choosing. And for that sweet tooth, try one of the homemade gelatos at Double-Dip.

You'll feel a million miles from any other guests at your private villa in the trees (some are closer to the sea). Topped with green living roofs, each has a private pool and sundeck, sleep-inducing mattresses and private bar selection. The living areas are decorated in cool pastels (with a TV and Nespresso machine) and the bathrooms have deep, oval tubs with a view. Some villas have two bedrooms, the most impressive being The Beach Retreat. On a private strip of beach, it has a large dining room, shaded pool and a bathtub on the rocks.

Before diving over reefs alive with colour, enjoy a stroll round the boardwalk that skirts the island or venture into the forest to see its riot of birdlife. Learn about Six Senses' conservation work, watch a film at the outdoor cinema and 'play the kid' on one of the many adult jungle gyms - or curl up with a book in the library's wicker pods. Jump aboard a speedboat to explore nearby islands (with a picnic beneath the palms), kayak or paddleboard down the coast, and lay out on powder-white beaches. Hike through Ream where you could spot a rhesus monkey chattering overhead, and stop for a dip in the Kbal Chhay waterfall.
