About Madang

Madang combines a compact coastal town with some of Papua New Guinea's most accessible marine landscapes. Reefs, islands, mangroves, fishing communities, local markets, and nearby cultural routes can fill several days, but boats, tides, weather, and local permissions determine what actually runs. Use established dive or boat operators, confirm safety equipment and communications, and do not touch coral or wildlife. Keep valuables secure, ask before photographing people, check current travel guidance, and leave enough time between marine activities and onward domestic flights.
