Private Island: Little Thatch Island, British Virgin Islands
With its terracotta-tiled veranda, louvered shuttered windows, and open-air rooms, Sea Grape Cottage is the sole rental cottage on a small islet in the British Virgin Islands. This comfortable and private place is reachable only by water taxi. That’s not to say there are no distractions, as the clear waters surrounding the islet are perfect for swimming, snorkeling, and fishing while the white sand, palm-fringed beach out the side door may well make it challenging to stay indoors. This pricey bit of privacy goes for $6,400 in low season and on up to $8,950 at Christmastime.
