Little Palm Island Resort & Spa
Little Torch Key, FL
Though it's separated from the Florida Keys "mainland" by just a few miles, Little Palm Island (a 2012 Gold List resort) is accessible only by boat or seaplane. Once on the 5.5-acre island, guests can stay in one of just 15 thatched-roof bungalows—all of them oceanfront—and no televisions, phones, or kids are allowed.
San Martin, CA
Tucked into the foothills of Northern California's Santa Cruz Mountains, Gold List-ranked property CordeValle claims 1,700 acres of countryside for guests seeking tranquility. But there's also tennis, golf, a spa, and the Clos La Chance winery and vineyard if you're looking for activities.
The Wakaya Club & Spa
Wakaya Island, Fiji
To get to this 2,200-acre private island (owned by Fiji Water founder David Gilmour), you'll need to board the Wakaya's own private Cessna Grand Caravan. After touchdown, guests can either choose to be the center of attention, courtesy of 12 staff members for every person, or opt to be completely alone: The resort offers a private beach picnic, during which guests are left with only a walkie-talkie to communicate and a guarantee that there is no other human being within three miles.
