"A few decades ago, architect Nick Troubetzkoy and his entrepreneurial wife, Karolin, began their journey in St. Lucia, buying Anse Chastanet resort and transforming it into a Caribbean mainstay. In 2007, they opened a sister property, the 29-room Jade Mountain: a one-of-a-kind resort with open-air rooms overlooking the island’s legendary twin Pitons. Jade Mountain calls its 24 accommodations “sanctuaries”—and they are. With a seamless blend of bedroom, living area, and a private infinity pool, these guest rooms seem to float into nature, thanks to the absence of a fourth wall. The five Sky suites average 1,650 square feet each; instead of private pools, they have a chromatherapy bathtub large enough for two. Sustainability and social responsibility are at the core of Jade Mountain. The resort recently appointed a Reef Life and Renewal Ambassador to help look after the surrounding waters (guests can help plant coral in new nurseries). And a million-dollar refurbishment introduced a line of furniture crafted by the in-house carpentry masters using tropical hardwoods sourced with responsible forest management. From $1,455." - Jennifer Flowers
