Here’s a simple way to avoid those pesky airline baggage fees: Don’t pack clothes. Travel to clothing-optional destinations and events is on the rise, as more hotels, resorts, and even cruises are catering to guests who want to strip down. But the trend goes beyond aging hippies lounging around '70s-style campsites or risqué resorts in the Caribbean: Nudist vacations are increasingly popular among all types of travelers, in some of the most unexpected places. Reasons for the uptick, according to the American Association of Nude Recreation (www.aanr.com): Nude vacationing is more relaxing, relieves stress, and offers travelers a welcome respite from the (fully-clothed) crowds. Here, we give you the top 10 nude vacations, along with some bare facts about clothing-optional travel. Go grab a towel and get ready to let it all hang out – just make sure to pack plenty of sunscreen. Take a (safe-for-work) peek at the destinations with our Nude Vacations slideshow.
