Even if you can't escape to one of these locales in the near future, a little daydreaming never hurt anybody.
Sugar Beach, St. Lucia
A butler will pick you up at your room and drive you to the spa at this recently-rebranded luxury resort nestled between St. Lucia's famous Piton mountains, so vast that its villas, restaurants and other amenities are spread across more than 100 acres. After checking in for your service, your therapist will lead you up to your own personal tree house treatment gazebo, suspended over running water so you can take in the elements around you. Opt for a peppermint chocolate massage with massage oil made from organic, locally produced cocoa oil, locally produced organic coconut oil and essential oil of peppermint, or the Sulphur Seduction, which utilizes the nearby Sulphur Springs and volcano to promote well-being, or an all-natural body scrub using fruits and herbs grown right at the resort. When you're finished, take a few minutes in your private outdoor shower to further extend your bliss.
Before they wed, JP and Ashley from "The Bachelorette" had a very romantic rendezvous at this Fijian resort (and by the way, the date they had is also available for you to book, as the Passion Under Palms package). Every item incorporated into your treatment is homegrown when possible — from the banana leafs used in body wraps to the coconut shavings used in exfoliating body scrubs. The three wooden straw huts (called Bures) are candle- and lantern-lit, and you can hear trickling waters and bird callings during your service.
MesaStila has been an active coffee plantation since Dutch Colonial times — you'll see its heritage across its 55 acres, from the railway station to its owner's residence. The property is situated within eight volcanoes, and it houses Southeast Asia's sole authentic Hammam.
Tabacón Grand Spa Thermal Resort, Costa Rica
Eight miles north of tourist-heavy town La Fortuna is this tropical oasis, where treatments take place in open-air bungalows in a private garden area of the rainforest. Taking a dip in the area's famous hot springs is recommended for the health benefits they're said to provide, and easing in should be no problem — the mineral waters have been warmed by the nearby Arenal Volcano, and one thermal pool boasts a swim-up bar and thermal water slide. Eco-friendly travelers will be happy to hear that the resort is 100 percent carbon-neutral and that the spa utilizes local ingredients like volcanic mud and thermal waters.
