Jade Mountain Resort, St. Lucia
Jade Mountain is a popular hideaway among celebrities and couples; as an adults-only property, its tranquil vibe is hard to match elsewhere on the island. With “missing” fourth walls, the upscale, unplugged (no TVs or radios) rooms look out onto the ocean and the Pitons, gorgeous mountains that rise straight out of the water.
