Viking Cave

Viking Cave is a limestone sea cave on the northeastern coast of Phi Phi Leh Island in Ao Nang, Mueang Krabi District, Krabi Province, Thailand. Located within Hat Noppharat Thara–Mu Ko Phi Phi National Park, it is known for ancient wall paintings of boats, including a vessel resembling a Viking ship, and for edible-nest swiftlet nests harvested for bird's nest soup. The cave interior is closed to visitors, who view the site from boats during island-hopping tours.

Visitors approach Viking Cave by long-tail boat or speedboat and view the cave from the water, as landing and entry inside are prohibited. The site features a large limestone cliff with a cave opening, bamboo scaffolding used for swiftlet nest harvesting, and ancient paintings visible on the walls. The surrounding area offers clear turquoise water, karst scenery, and photo opportunities. The stop is typically brief as part of a Phi Phi Leh island-hopping itinerary.

Viking Cave contains prehistoric rock paintings estimated to be 3,000-4,000 years old, depicting various vessels including what appears to be a Viking ship, Chinese junks, and other boats, reflecting early maritime activity in the region. The cave has also been historically used for harvesting edible-nest swiftlet nests.

The cave is culturally significant for the traditional harvesting of edible-nest swiftlet nests used to make bird's nest soup, a valued delicacy. The harvesting is regulated and conducted using bamboo scaffolding, representing a long-standing local livelihood within the Phi Phi Islands.
