ST. LUCIA —The influential travel magazine Travel + Leisure again named St. Lucia’s Jade Mountain as one of the top 100 hotels in the world and number 1 in the Caribbean.

Jade Mountain’s latest recognition by the Travel + Leisure World’s Best Awards 2015 is the fourth time and third year in a row readers have cast top votes for St. Lucia’s storied resort. The magazine listed Jade Mountain as the No. 1 Caribbean resort, which defines the very best in travel.

Much of Jade Mountain’s success can be attributed to the continuing direct involvement of owners Nick and Karolin Troubetzkoy in the daily operations of this privately owned, independent resort. The couple’s passion and limitless enthusiasm inspire their resort team, which includes majordomo butlers assigned to each guest to ensure the resort experience around the clock, from arrival to departure.

“Travel + Leisure readers are incredibly savvy travelers who ,in addition to luxury, look for sustainable and responsible practices, so this is very high praise indeed,” said Karolin Troubetzkoy. “And we are delighted at the guests’ responses to our resort into which we invested so much of our time, resources and passion.

But you have to remember our staff, of which we are most proud, are world class in their technical skills and world leaders in genuine hospitality and warmth.”

Crediting her husband Nick Troubetzkoy’s vision and creativity in designing and building the stunning mountainside resort, where every room has a view of the twin Pitons, a UNESCO World Heritage site, she also points to their deep commitment to sustainability: “Nick wanted to ensure everything was sustainable, which is why the tiles in the infinity pools, as well as on many of the walls, were made from recycled glass. The stone was carved by local masons and, among many other sustainable products, the furniture was lovingly carved by local craftspeople.”

She is also proud of the way the twin resorts have contributed to the betterment of the communities that surround them: “With our sister property, Anse Chastanet, Jade Mountain employs almost 500 people, overwhelmingly from local communities, and that’s the way we like it. In fact, we have multiple generations of families working here, and it’s fun to see younger staff being instructed by their grandparents on the way we do things at the resort.”

And it doesn’t end at the resort. The Troubetzkoys are active in local and regional issues, with Karolin Troubetzkoyat the helm of the St. Lucia Hotel and Tourism Association, which comprises private sector players in the tourism sector. Next year, she will also take over the presidency of the Caribbean Hotel and Tourism Association, which shapes regional policies for its greatest revenue earner, tourism. She is also involved in charity and community work.

“It’s important for us to give back to our country and to our region, and these are just some of the ways we can contribute,” she said.

Nick Troubetzkoy, the resort chairman, architect and builder, started his love affair with St. Lucia and the Caribbean with the opening of Anse Chastanet in the 1970s. His revolutionary architectural approach produced the stunningly bold and unique Jade Mountain, which opened in early 2007 on its perch on a mountain top overlooking St. Lucia’s landmark twin Piton peaks glittering in the azure Caribbean Sea. The resort has 29 suites in total, which are called sanctuaries. In 24 of the sanctuaries, an extravagantly sized private infinity pool seems to be floating out into nature.

Jade Mountain also runs an organic farm and has an onsite chocolate laboratory, making chocolate from its own estate-grown cocoa trees. Guests have privileges at the adjoining Anse Chastanet, with two beaches, additional restaurants and excellent resort activities, including jungle biking, scuba diving, hiking and bird watching.
