Milne Bay Marine Park is a vibrant marine protected area in Papua New Guinea known for its extraordinary coral reefs, abundant marine biodiversity, and world-class diving opportunities.
Milne Bay Marine Park covers a large portion of the eastern tip of Papua New Guinea, encompassing extensive coral reefs, seagrass beds, mangroves, and a rich variety of marine ecosystems. The area stretches along the coastline of Milne Bay Province, featuring island chains and bays which provide critical habitat for hundreds of marine species, including coral, fish, mollusks, and endangered sea turtles. The park plays a vital role in protecting traditional fishing grounds of local indigenous communities while promoting sustainable tourism.
The region is famed internationally for its spectacular underwater landscapes — vibrant coral gardens, walls, and bommies that attract divers and snorkelers from around the world. The waters teem with diverse wildlife such as reef sharks, manta rays, nudibranchs, and giant clams. On land, the surrounding tropical islands support lush vegetation and provide a home for seabirds and other wildlife.
Historically, Milne Bay holds cultural and historical significance, as it was the site of the pivotal Battle of Milne Bay during World War II. Visitors to the marine park can explore both natural and cultural heritage sites while enjoying activities like scuba diving, snorkeling, kayaking, and guided eco-tours.
Local communities actively participate in management efforts to ensure the park remains a healthy marine ecosystem, balancing conservation with livelihood and tourism. The appeal of Milne Bay Marine Park lies in its combination of raw natural beauty, marine diversity, and a relatively untouched underwater environment that supports both recreation and research.
