Phra Nang Beach (not to be confused with nearby Ao Nang) is the southern strip of sand in Railay Bay.  With duvet-soft sand, clear shallow water for safe swimming, two small islands (Koh Rang Nok and Nai), coral reef, and caves, Ao Phra Nang has all the ingredients of a perfect beach. All this, set against a backdrop of picturesque limestone cliffs that provide natural shade from the hot afternoon sun, and offer rock climbers one of the most stunning sites for this thrilling activity in Krabi Province.
          At the bottom of the limestone cliffs lies the Princess Cave or Tham Phra Nang Nok. A bizarre sight for some foreign visitors, local fishermen still leave offerings even though it became a local tourist attraction. It contains the same kind of items as the original cave. Adventurous explorers can also find a cave at the western end of the beach: accessible with the help of ropes, it is not a too challenging hike, and the reward is a fantastic view to the Andaman Sea and the islands lying off the coast.

A second cave - right next to the original - is also used for offerings and prayers; it contains the same kind of items as the original cave.  Phra Nang is a great beach to simply hang out.
