About this site
The Clan Mcwilliam Wreck lies in the Vava'u island group of northern Tonga, a chain known for sheltered channels and volcanic reef formations, typically reached by boat from the town of Neiafu. Divers exploring the site have reported a mix of reef fish making use of the wreck structure, including coral damselfish, flagtail triggerfish, humbug dascyllus, moon wrasse, pinstriped wrasse, and several parrotfish species such as the Indian bullethead, surf, and yellowbar parrotfish, along with lined bristletooth surgeonfish moving over the hull.
