The 10 Best Adults-Only Hotels in the United States

Everyone needs a little get away without the kids.

— -- There's something to be said for getting away without the kids. But that serene vibe you seek can totally be ruined by the presence of other guests' children. So if you're looking for a relaxing getaway -- whether a romantic rendezvous or a girls' weekend -- here are the top 10 adults-only hotels in the U.S. No need to worry about splashing in the pool or wailing babies in the restaurant at these 10 beautiful resorts.

1. Post Ranch Inn

Bug Sur, California

2. Auberge Du Soleil

Rutherford, Napa County, California

Despite its intimate size (with just 50 rooms), this luxurious inn has all the amenities of a larger resort: a 7,000-square-foot luxury spa, a lovely pool, and a Michelin Star restaurant. Views of the surrounding countryside are phenomenal, the grounds are lush and peaceful (thanks, in part, to a "no children under 16" policy), and the homey rooms all come with huge terraces (and, in most, fireplaces and soaking tubs). It's a truly special, romantic retreat, and it's location in Rutherford is convenient for exploring Napa Valley.

3. Travaasa Austin

Austin, Texas

As a four-pearl property, Austin's Travaasa can't quite compete with the likes of Post Ranch Inn and Auberge du Soleil (both five-pearl hotels). But it nonetheless comes in at No. 3 on our list, and not just for its peaceful atmosphere achieved through its gorgeous setting amid forested hills of the Balcones Canyonlands Preserve, and no-children policy. Its 72 rooms are housed in seven buildings and offer private balconies with beautiful canyon or garden views. Hiking trails, an infinity-edge pool enclosed by a wooden deck, and a luxurious spa are just some of the amenities here, and there's a restaurant serving organic, local fare, with many of the ingredients used sourced from the hotel's own farm.

4. La Mer Hotel and Dewey House at Southernmost Beach Resort

Key West, Florida Keys, Florida

The 19-room La Mer Hotel and Dewey House is an upscale, adults-only property built at the turn of the century on South Beach. Despite its size, this bed-and-breakfast offers extras such as fitness center access, spa treatments, multiple pools and bars, and beachfront yoga (for a fee) thanks to its proximity to a sister hotel (which does allow children). Guest rooms are beautifully decorated in a classic style, and have flat-screen TVs, mini-fridges and coffeemakers; some open to balconies. The property serves free breakfast, along with occasional treats like chocolate-covered strawberries -- although this all comes at the cost of a resort fee.

5. Ho'Oilo House

Luhaina, Maui, Hawaii

With just six rooms arranged around a beautiful common area that’s all decked out in lavish Balinese-style decor, Ho'oilo House is about as opposite of a generic mega-resort as you can get. The adults-only bed-and-breakfast offers an intimate, romantic alternative to busy chain hotels. Note that amenities are limited to a great continental breakfast and a small, lovely pool, but the experience here less about action and more about relaxing and enjoying the great views of the ocean below.

6. Canyon Ranch

Tucson, Arizona

Canyon Ranch is a health spa and all-inclusive resort in north Tucson near the Santa Catalina Mountains. Here the focus is on wellness, nutrition and fitness so it makes sense that it's an adults-only property; while children over 14 can stay here, guests must be 18 to participate in various programs, so very few families bring their teens. Daily fitness classes along with informational lectures and a menu packed with healthy, low-calorie food help guests to jumpstart (or maintain) a healthy lifestyle. The color palette of the Southwest-inspired the decor of the rooms, which come complete with flat-screen TVs, free Wi-Fi and iPod docks. Immaculate, peaceful grounds and focused spa treatments all provide an incredibly relaxing environment. It offers more amenities than both Ho'oilo House and La Mer Hotel, but its larger size (180 rooms) means it's slightly less intimate, and thereby comes in sixth on our list.

7. Vintro Hotel South Beach

Miami Beach, Miami, Florida

Vintro Hotel South Beach is an upscale Art Deco boutique hotel for the 18-and-up crowd looking for a hip scene. The 50 guest rooms have retro furnishings in citrus tones, and feature flat-screen TVs, Illy espresso machines, and rainfall showerheads. It offers quite a few amenities to lure travelers: vouchers for beach chairs and towels; a rooftop plunge pool; on-site fine dining restaurant; lobby bar; free bicycles; and free Wi-Fi.

8. The Mermaid & The Alligator

Key West, Florida Keys, Florida

The Mermaid & The Alligator is a nine-room upscale bed-and-breakfast housed inside a historic Victorian estate; children under 16 are not permitted. The owners have taken great care to renovate the home with bold and vibrant decor and updated furnishings, and some rooms include romantic perks like deep soaking tubs. Located on Truman Street, three blocks from popular Duval Street, the home is a quiet and peaceful area that is steps from the heart of the entertainment district. There is a lush interior garden with hammock, lounge chairs and plunge pool, but note that there are no on-site restaurants for lunch and dinner.

9. The Lodge at Woodloch

Hawley, Pocono Mountains Region, Pennsylvania

Deep in the Poconos, The Lodge at Woodloch is an upscale adults-only retreat where the focus is on the spa. It has all the usual perks of an all-inclusive resort in the region, with acres of woodland, a private lake and an adjacent golf club, but the restaurant here is a grown-up, farm-to-table affair with some of its produce sourced from its own garden. Guests can spring for chef-curated dinners, with cocktails and a wine list worth exploring. Rooms are quite as luxe as those in the properties mentioned above, but perks like an 18-hole golf course nearby and an indoor pool with heated waterfall features make it a great adults-only pick in the U.S.

10. The Standard Miami

South Beach, Miami, Florida

For those looking for a more party-centric adults-only atmosphere than one focused on serenity, The Standard Miami is a solid option. It may be about a mile from the beach, and rooms are both small and generic, but here guests enjoy perks like a renowned spa, a massive 24-hour pool with hot tubs, two popular lounges and a juice bar. Plus, for a small fee, guests can select the "standard time" option, which means you can check in and check out whenever you want throughout the day.
