    StandoutExceptional marine biodiversity

    Hairball One in Sulawesi is a classic muck diving spot. Expect to spend your dive scanning the volcanic sand and silty bottom for the smaller, stranger creatures. We’ve found frogfish, various nudibranchs, and pipefish here. It’s a site for macro photographers and those who enjoy a slower, more deliberate dive, searching out the cryptic.
