Diu Diu Cave
Diu Diu Cave is a karst cave located in Waigani, Milne Bay Province, Papua New Guinea. The cave is one of the most beautiful caves in Papua New Guinea. The entry to Diu Diu Cave is a little challenging. You'll have to wade through water and mud with a ceiling that's often barely 80 cm high after ascending down into the cave river. This excursion involves a lot of mud and guano contact. Eels, prawns, spiders, and bats are among the cave's inhabitants.
This cave is undeveloped and quite difficult to access. It's part of Milne Bay Tourism's ecotourism trip. The three-hour half-day trip includes an escorted vehicle ride, trekking, and a cave trekking tour. Rubber boots, old clothes, and clothes to change are recommended for people with a medium level of physical fitness.
