Kho Phi Phi Leh..: In contrast to Phi Phi Don, Phi Phi Leh remains uninhabited Phi Phi Don bring visitors on Day Viking Cave. Another feature of the cave are the nests of the edible-nest swiftlet which are used in bird's nest soup. Agile collectors climb rickety bamboo scaffolding to reach the nests, which are so valuable that the caves guards. In a bid to halt the illegal trade of the nests, staying overnight on the island is prohibited. There is excellent snorkeling at the coral reefs of Ao Maya, a bay in the southwest corner of the island.
