Peak viewing: Jade Mountain, St Lucia, Caribbean

You'll feel like a James Bond villain in unbelievably luxurious island lair Jade Mountain in St Lucia. Architecturally astonishing and blessed with breathtaking views of the Caribbean Sea and balmy bayside, it teams zigzagging stone walkways with adventurous alfresco spaces and cascading koi pools. Each of its 29 colossal suites has an open fourth wall so you can admire the island's landmark Piton Mountains (24 also flaunt private infinity pools with vibey fiber-optic lighting). Throw in a glam main pool, a lofty terrace bar and a seafood restaurant.
