"This is one of the finest private islands in the Indian Ocean, and certainly one of the most dramatic, run by the sure-handed spa specialist group, with rewilded nature that’s been given the time and space to make a comeback. Up in the trees, or secluded amid rocks and pristine forest, the villas are the closest thing to super-smart, minimalist treehouses. They are floored in local Balau wood, fronted in glass that allows the surroundings to take center stage, and decked out in soothing ocean hues. The area feels both very primitive—and, thanks to eco-initiatives, very advanced. This is the place that, when you are having a bad day back at home, you dream about. —Lisa Grainger"
