Viking Cave is part of the Hat Noppharat Thara-Mu Ko Phi Phi National Park.
Viking Cave is located on the northeastern side of Koh Phi Phi Leh, within the Krabi province of Thailand. The site is characterized by limestone karst formations containing ancient, weathered wall paintings depicting various types of ships. The cavern is a primary harvesting site for swifts' nests, which are a valuable ingredient in traditional bird's nest soup. Scaffolding structures made of bamboo are built inside the cave to allow workers to scale the high walls for nest collection. Public access to the interior of the cave is prohibited to protect both the nesting environment and the fragile rock art. Visitors typically view the cavern from boats anchored at a safe distance in the surrounding turquoise waters. The site remains a protected concession area managed by local authorities to regulate the harvesting industry.
