Jade Mountain is one of the most romantic resorts not only in the Caribbean, but the world, thanks to its incredible Piton views and extraordinary design. The 29 enormous suites, called “sanctuaries,” are hands-down the highlight; through the innovative, open fourth wall, each has a view of a sea from the entire room – from the canopied bed, raised whirlpool tub, and (in all but the entry-level category) private infinity pool.
