The Best Adults-Only All-Inclusive Resorts in the United States

All-inclusive resorts in the United States have moved well beyond standardized buffets and poolside drink service. A small but growing subset caters exclusively to adults, with a focus on design, programming, standout dining, and a more low-key atmosphere than family-oriented resorts.

From a wellness-driven retreat in the Arizona desert to a historic estate in upstate New York, these 14 adults-only all-inclusive properties on Afar’s latest Hotels We Love list offer a wide variety of experiences with offerings that reflect their settings.

Alila Ventana Big Sur

Set on 160 acres of redwood forest along the Big Sur coast, Alila Ventana Big Sur is an adults-only property with 54 rooms and suites, arranged in low-rise cedar buildings spaced across redwood groves and open meadows. The rate includes all meals—served at the Sur House restaurant or in-room—as well as a defined schedule of activities, such as guided hikes, yoga, tai chi, and meditation, plus practical extras like trail gear and local shuttle service.

The facilities include two heated pools, open-air Japanese-style hot baths, and a spa that draws on regional botanicals. Rooms are generously sized, with terraces, fireplaces in select categories, and furnishings in wood and leather.

Bungalows Key Largo

The oceanfront Bungalows Key Largo welcomes guests age 21 and up, and it is renowned for its namesake bungalows, which have a private outdoor area with a soaking tub and shower. When not relaxing by one of two pools, guests can snorkel, stand-up paddleboard, kayak, or stretch during beachfront yoga.

Additional amenities include top-shelf liquor at the three bars, an on-site fitness tiki hut equipped with Peloton bikes, live entertainment (including karaoke, trivia, calypso sounds, and acoustic tunes), and five stylish bars and restaurants. (A sixth, the steak-and-seafood fine-dining restaurant Bogie & Bacall’s, is not included.) For an extra fee, guests can indulge in a spa treatment (price varies) or a floating tiki boat ride ($50 per person).

Canyon Ranch, Tucson

The 150-acre Canyon Ranch Tucson is a spa resort near the Sonoran Desert and Santa Catalina Mountains, less than 30 minutes by car from Tucson. The inviting guest rooms and suites, in warm color palettes inspired by the desert surroundings, are sanctuaries unto themselves, while on-site amenities include nine fitness studios, a spa and salon, a labyrinth, a ropes course, a meditation garden, and three outdoor pools.

There’s a wide array of daily activities, including chef-led cooking demos, yoga, pickleball, hiking, and biking. Sit-down meals and grab-and-go items like salads and smoothies are included in the room rate, allowing guests to dine at their own pace.

Castle Hot Springs

Castle Hot Springs, located one hour’s drive north of Phoenix in a remote valley of the Sonoran Desert, dates back to the late 19th century, when it first became a wellness destination for travelers seeking the curative benefits of its healing waters. It was reborn in 2019 as a luxury all-inclusive, with accommodations ranging from sleek brand-new Sky View Cabins and Spring Bungalows with outdoor soaking tubs to the 100-year-old Historic Cottage for up to six people.

There are three hot springs, ranging from 86 degrees to 106 degrees Fahrenheit, and the natural spring water also supplies the resort’s central swimming pool. The on-site spa offers services that include massages, facials, and a Reiki menu, or you can book wellness sessions for a chakra tune-up, breathwork, or an astrology reading. When you’re not soaking, daytime activities might include traversing the on-site via ferrata course and e-bike desert rides.

Golden Door

Set in the mountains of San Marcos, California, less than an hour’s drive north of San Diego, Golden Door has become one of the world’s most exclusive wellness and spa resorts since its founding by original owner Deborah Szekely in 1958. Unlike most all-inclusive resorts, the rate includes spa treatments like in-room massages, skincare or body treatments, herbal wraps, and manicure-pedicures. Meanwhile, all 40 accommodations have private decks or patios overlooking the tranquil Japanese garden. The 5:1 guest-to-staff ratio offers a level of individualized attention rarely found at this scale.

Between personal training sessions and dozens of fitness and wellness classes, guests can walk the property’s 30 miles of private hiking trails and citrus groves, take cooking classes, or enjoy the farm-to-table cuisine, cooked from locally sourced seafood and poultry and fruits and vegetables harvested from the on-site farm.

The Green O, Montana

For a romantic adults-only, all-inclusive experience, look no further than the Green O, a hotel-within-a-hotel at the 37,000-acre Resort at Paws Up, about a 40-minute drive east of Missoula Airport. Green O guests can take their pick of one of 12 “hauses” surrounded by evergreen trees, with more than 1,000- square feet of indoor-outdoor space, and amenities like hot tubs and fireplaces.

Outdoor enthusiasts will love the variety of activities: archery, pony rides, mountain biking, and snowshoeing are all included in the room rate, while hot air balloon rides, horseback riding, and skiing in the winter are available at an additional cost. Green O guests can enjoy multi-course tasting menus sourced with locally raised, farmed, and foraged food each evening, while more casual daytime meals include grilled bison tenderloin skewers or kimchi grilled cheese.

Little Palm Island Resort & Spa

The only adults-only private island resort in the USA, the four-acre Little Palm Island sits 28 miles east of Key West. At this Relais & Châteaux resort, each of the 30 thatched-roof bungalows has a private outdoor shower and veranda (and no television) and is hidden in tropical foliage. Aside from relaxing on the secluded beach, many guests spend time in SpaTerre, which offers Balinese and Thai treatments, or on the provided kayaks and paddleboards. Diving, fishing, and sailing excursions are also available.—Devorah Lev-Tov

The Lodge at Woodloch

Set in Pennsylvania’s Pocono Mountains, about a 2.5-hour drive from New York City, the Lodge at Woodloch is the adults-only sister property to the nearby family-friendly Woodloch Pines Resort, about two miles down the road. The 58-room spa retreat has accommodations with ample lounge space and private balconies, a full slate of daily programming, from guided foraging and kayaking to axe throwing, plus six miles of trails for hiking and forest bathing.

Miraval Arizona

Located an hour outside of Tucson in Arizona’s Sonoran Desert, Miraval Arizona opened in 1995 and joined the Hyatt portfolio in 2017. The 118 guest rooms are housed in adobe buildings and feature a modern, desert-style aesthetic with wood furnishings and private patios—some with tiled fireplaces.

Wellness here is holistic and immersive: The Miraval Equine Experience involves working with horses in a way that allows guests to notice their own personal patterns and inhibitions, while Discover Your Dosha teaches guests about their Ayurvedic constitutional type (dosha) and how it can be optimized for health and wellness.

Miraval Berkshires, Massachusetts

Set in Lenox in the Berkshires, about a 2.5-hour drive from Boston, Miraval Berkshires builds each stay around a full program of included activities. The daily lineup ranges from meditation, yoga, and hiking to tarot readings, cooking classes, and seasonal offerings like snowshoeing, all designed to give structure to the day (but without requiring it). There’s also a swimming pool and the Balinese-inspired Life in Balance Spa for treatments booked separately.

Guest rooms also focus on wellness, with details including Tibetan singing bowls and meditation cushions. Meals and snacks rotate with the seasons, often incorporating ingredients from the property’s own gardens, beehives, and chicken coops, as well as nearby purveyors like High Lawn Farm in neighboring Lee. For an additional cost, guests can opt for farm-to-table picnics, garden tours, sustainable seafood workshops, and kombucha brewing.

The Point Resort

Once a Rockefeller-era Great Camp in the Adirondacks, the Point is now part of Relais & Châteaux and remains one of the region’s most distinctive luxury retreats. It sits on 75 private wooded acres on the shores of Saranac Lake, with seasonal outdoor activities like boating, biking, and hiking in summer and ice-skating and cross-country skiing in winter.

There are only 11 suites and cottages, each individually designed with such features as wood-burning fireplaces, deep soaking tubs, and plush beds. Notably, rooms are intentionally free of televisions and Wi-Fi, reinforcing the sense of escape. In the evenings, multi-course communal dinners take place in the Great Hall, where a formal dress code—cocktail attire or black tie, depending on the night—nods to the property’s origins. The ever-changing menu might include wagyu short ribs with lobster mushrooms or celery root gratin. The setting is transporting, with soaring ceilings, 19th-century Hudson River School oil paintings, and mounted game, while drinks and well-curated wines are readily available throughout the property.

Post Ranch Inn

For more than 30 years, the Post Ranch Inn, which sits along a cliff 1,200 feet above the Pacific Ocean, has been a go-to retreat for devotees who believe well-being starts with a place that honors its natural environment—and treads lightly on it, too. Big Sur architect Mickey Muennig designed the 40 guest rooms that rely on solar power; all were fashioned out of recycled wood, and the structures blend in with the Santa Lucia Mountains.

Views through enormous windows face either the Pacific or the mountains. Wellness plays a role in every experience on offer, whether it’s a reflexology treatment, a shaman healing session, a doctor-led sleep program, or a private guided hike or meditation session in the nearby ancient forests.
