The Phi Phi Islands, located in Krabi, Thailand, are renowned for their stunning limestone cliffs, pristine beaches, and vibrant coral reefs. Maya Bay, made famous by the movie "The Beach," is a highlight, though subject to closures for ecosystem recovery. Accessibility can be challenging, involving boat trips from Phuket or Krabi. Both solo and guided tours are popular; guided tours often provide convenient transportation and snorkeling opportunities. The best time to visit is during the dry season (November to April) for calmer seas and sunshine. Expect to spend anywhere from a day trip to several days exploring the islands. Costs can vary widely depending on accommodation and activities, but a mid-range budget should suffice. Be mindful of strong currents when swimming and respect local customs.
