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. Organic cuisine is served from a chic open-air restaurant, and guests can expect unwavering peace and quiet throughout (there are no TVs or children). Though there is no beach, guests can take a short shuttle ride or hike down to use the two beaches, free water sports, and dive center at sister property Anse Chastanet. All in all, Jade Mountain is well worth the price and bumpy ride to get there. Families -- our couples looking for easier beach access -- should consider Sugar Beach, a Viceroy Resort. 

Ladera Resort is an adults-only, luxury hotel set on a forested ridge overlooking the Pitons. With private plunge pools and lots of local furniture, the resort’s 32 rooms, which are completely open to the elements on one side, make a bold impression. The rustic, chic decor found throughout the rooms and common areas connects guests to nature without skimping on style -- although the open-air spaces and lack of TVs won’t be to everyone’s taste. Features include a wonderful restaurant and a clifftop pool, both with great views, plus a spa with outdoor mineral pools. There’s no beach on the property, but the resort provides free shuttle service to nearby Sugar Beach. Travelers may also want to consider the more expensive Jade Mountain Resort, right on the beach.

Anse Chastanet Resort is a four-pearl hotel located a short drive from the town of Soufriere. Its 49 rooms have oodles of character plus incredible views, and some are partially open air, with only three walls. Set on a hilly property amid hundreds of acres of tropical vegetation, this resort is designed to be in harmony with the natural environment. Several open-air restaurants make the most of the surrounding tropical scenery and there are two picturesque beaches, but not all guests will love the resort’s conscious choice to not have TVs, and there's no pool. Guests might want to compare rates and amenities with nearby Ladera Resort (although it doesn’t have beach access). 

This luxurious Viceroy is truly a stunner. It has arguably the best location on St. Lucia, right in between the Pitons, St. Lucia's famous volcanic spires, and on a beautiful white-sand beach. Its 79 rooms are minimalistic, chic, and mostly white, and all come with private plunge pools, butlers, and 24-hour room service; the larger villas and cottages offer living rooms and huge bathrooms (some with outdoor showers and hot tubs). Features include a family-friendly pool, fitness center, tennis courts, and free water sports. The romantic tree-house spa is one of the island's best. The resort's restaurants and bars are pricey, but all-inclusive rates are available to help guests keep costs in check. On St. Lucia, only the adult-only Jade Mountain can compare -- but it lacks the on-site beach found here, and its spa isn't as nice. 

Stonefield Estate Villa Resort & Spa is a four-pearl, adults-only resort located just outside the town of Soufriere. Most of the 17 rustic-chic villas have large separate living areas and private pools, all with kitchenettes or full kitchens. The open-air restaurant and pool make the most of the resort’s striking views of Petit Piton and the Caribbean Sea below. Other amenities include a spa and a fitness center, and free freshly prepared breakfast is included in the room rate. The main downside here is the lack of beach access, although the resort provides free shuttle service to nearby beaches. Travelers might want to compare rates and amenities with nearby Anse Chastanet Resort, which has direct access to two gorgeous beaches.
