7 incredible outdoor spas

<a target="_blank" href="http://www.oyster.com/los-cabos/hotels/grand-solmar-lands-end-resort-and-spa/">Grand Solmar Land's End Resort & Spa </a> Cabo San Lucas, Los Cabos, Mexico Grand Solmar's spa overlooks the ocean at Land's End Terrace and features beachside massage cabanas. It offers a long list of indoor and outdoor treatments, as well as a Temazcal sweat lodge for a full-body cleansing. Oyster's Treatment Pick: The sweat lodge may be kinda cool, er, we guess hot, but the real treat at Grand Solmar's spa is the Thalassotherapy treatment which uses seawater directly sourced from the Mar de Cortés.

<a target="_blank" href="http://www.oyster.com/costa-rica/hotels/arenal-nayara-hotel-and-gardens/">Arenal Nayara Hotel & Gardens </a> La Fortuna/Arenal, Costa Rica The beautiful Arenal Nayara's 44 individual bungalows, restaurant, wine bar, and spa are all tucked into incredibly lush grounds. Nayara Spa is beautifully built into the forest, and a few of the treatment rooms have stunning views. Oyster's Treatment Pick: The setting is so calming, and the treatment so soothing, that you may fall asleep -- but the delicious smell of the coffee scrub will leave you feeling fresh and ready to start your day.

<a target="_blank" href="http://www.oyster.com/hawaii/hotels/four-seasons-hualalai/">Four Seasons Hualalai </a> Big Island, Hawaii, United States The pristine Four Seasons, the only five-pearl property on the Big Island, is unlike any other resort on the Kohala Coast. Lush and beautifully landscaped grounds surround private bungalow-style rooms and suites tucked along winding paths throughout the large property. The first-class spa includes a unique water garden, four outdoor hales, and saunas, which are spread out among lush garden pathways. The secluded outdoor area makes for a perfectly tranquil setting. Oyster's Treatment Pick: The spa includes several traditional Hawaiian treatments, such as the Lomi Lomi massage, a method passed down by "kupuna" (or "elders") that is meant to have sacred healing powers.

Terranea Resort Beaches - Santa Monica and Venice, Los Angeles, California One of just a few true mega-resorts in Southern California, the 100-acre, 582-room Terranea in Rancho Palos Verdes offers a range of features that's unrivaled among Los-Angeles-area properties, including nine holes of golf, five restaurants, three pools, gorgeous manicured grounds, and a top-tier spa. The spa facility encompasses a whopping 50,000 square feet and has 25 treatment rooms as well as its own pool and outdoor hot tubs. The three serene private treatment rooms, called VIP suites, are themed after the elements; the earth suite has a redwood sauna and shower, the fire suite has a fireplace, and the water suite has a copper tub and views of the Pacific. Oyster's Treatment Pick: With a long list of "signature spa rituals" split into categories "for morning and early afternoon" and "for late afternoon and evening," it's hard to pick a favorite. But we really love the invigorating volcanic ash wrap which is followed by a Vichy shower. Your skin will be glowing! (Oyster)

Dreams Tulum Resort & Spa Tulum, Riviera Maya, Mexico The 431-room Dreams Tulum is an all-inclusive megaresort in a secluded location near Mayan ruins, and about a 40-minute drive from Playa Del Carmen. It offers sprawling, manicured grounds, a white-sand beach, and a beautiful outdoor spa. Oyster's Treatment Pick: The spa offers two "tropical" anti-aging wrap treatments: one with pineapple and papaya and the other with mango and passion fruit. Both sound relaxing (and tasty) to us!

Four Seasons Resort Lanai at Manele Bay Lanai, Hawaii, United States The Four Seasons Resort Lanai at Manele Bay is a luxury resort secluded on the small island of Lanai, offering top-rated dining, a Jack Nicklaus-designed golf course, and a pristine pool and spa. The spa's treatments highlight Hawaiian ingredients with tropical fruit essences, while its remote location allows for frequent dolphin sightings. Oyster's Treatment Pick: We love the Ki pola ho'olu treatment. A cooling ti-leaf wrap, the signature treatment begins with a soothing covering of aloe vera followed by the body wrap. If you get a bit too sunburnt on the beach, the Ki pola ho'olu treatment is your new best friend! (Oyster)
