Ko Phi Phi, Krabi, Thailand

Located just 30 minutes by speedboat from either Phuket or Krabi, people question whether these pretty little road-less isles, immortalized in the film The Beach, are overexposed. Meanwhile, cleaned-up and considerably less congested since the tragedy of the December 2004 tsunami, Phi Phi Don and Phi Phi Ley (a marine preserve) continue to be unique hot spots, mixing nubile backpackers with wealthy jet-setters. There's no debate about Ko Phi Phi's enduring natural beauty: sugar sand setoff by turquoise waters and limestone cliffs, healthy coral reef and multiplying population of tropical fish.
