Viking cave is located on Phi Phi Leh island. The name of this cave comes from some paintings found inside, stylized drawings of some Viking ships. Inside the cave live 5 people in rotation, to preserve a particular species of swallow that produces a very valuable saliva.
Visiting Viking Cave also allows you to discover one of the most profitable local industries: the hunting/harvesting of swiftlet birds’ nests. Particularly prized in Chinese culture, these edible nests are believed to promote good health and to be specifically good for the skin. A local legend says that long time ago, sailors lost their boat during a storm and got stuck without food on one of the limestone islands lying in the mouth of the Phang Nga Bay. A cave located on this island was home to a colony of swiftlet, and the men could survive by eating their nests which gave them enough power to wait for rescue. The harvest of bird’s nests is rather a risky job: scaffolds are built with bamboo on which the hunters climb in the darkness to collect these precious items. Bird’s nests are sold, on average, for US$2,500 per kilo!
