There are two main islands that make up Ko Phi Phi, Phi Phi Ley & Phi Phi Don. Phi Phi Ley can be reached by a short boat ride but overnight stays
are not permitted. The Viking Cave on Phi Phi Ley is a cave right at sea level filled with bird's nests and painted on the walls are ancient paintings
resembling Viking boats.
Viking Cave, or in Thai, Tham Phaya Nak, is a cave on the eastern side of Phi Phi Ley Island. The cave's Thai name Tham Pya Nak was given by King Rama IX
when he visited Viking Cave in 1972. There is a particular boulder in the cave the resembles the head of a great serpent in Buddhism, the naga, and he named the
cave after this peculiar shape. Tham Phaya Nak is more popularly known as Viking Cave. It got this unusual name not because it was visited by ancient Vikings,
but due to the ancient cave painting found there that depict long boats resembling those of the Viking. The drawings are located on the eastern and southern walls
of the cave.
Viking Cave, Phi Phi Don
There are wall paintings of elephants as well as various boats, including European, Arab and Chinese sailing ships, baroques, motorboats, and steamships.
In all likelihood, the paintings are fairly recent, were probably executed by sea gypsies or pirates who stopover in the cave to shelter from unfavourable weather,
to transfer their cargo and to repair their vassals.

Bird nests are harvested from the cave walls, hence Viking Cave is out-of-bounds to visitors. The bird nest season is between February and April.
