Hidden Beach, Au Naturel Resort by Karisma

In case the "Au Naturel" in its name didn't tip you off, this adults-only all-inclusive is a nudist resort. If this is the type of vacation you've been searching for, you're in luck because you can do just about anything in the nude here. Everything from activities to dining can be enjoyed without clothes. And with just 43 suites, past guests said the property is intimate enough that you won't feel self-conscious embracing the nudist concept. Plus, the resort is shaded by a mangrove jungle and protected by 24-hour security to deter any interlopers. Rooms are outfitted with Jacuzzis for two, minibars, iPod docking stations and 42-inch plasma TVs. Recent visitors recommended booking a first-floor swim-up suite, where you'll have access to the pool right outside your terrace. When you're not relaxing by the pool or getting a massage at the beach, sign up for morning yoga or the resort's evening theme parties. If you're in the mood to venture off the property, you can head next door to the El Dorado Seaside Suites, but keep in mind that you must be clothed once you're off Hidden Beach property. At the neighboring hotel, you'll have access to El Dorado's 10 restaurants. But if you prefer to dine sans clothes, head back to Hidden Beach. Past guests say the food at the La Vista Restaurant is delicious, especially the breakfast and lunch menu. You'll find Hidden Beach on Kantenah Bay, about 19 miles south of Playa del Carmen on Mexico's Yucatan Peninsula.
