Railay Beach is a small peninsula located between the city of Krabi and the town of Ao Nang in southern Thailand. It is accessible only by boat due to the high limestone (karsts) cliffs cutting off mainland access. These cliffs attract rock climbers from all over the world, but the area is also popular due to its beautiful beaches and quiet, relaxing atmosphere. Accommodation ranges from inexpensive bungalows popular with backpackers and climbers, to the renowned jet-set resort of Rayavadee. The four main areas of Railay consist of Pranang, West Railay, East Railay and Tonsai, with Tonsai catering more to climbers.
