Port Vila Bay Night Dive

Port Vila Bay transforms at night into one of the Pacific's premier muck diving venues, with the sandy and rubble bottom of the harbour floor hosting a remarkable density of nocturnal macro species that are invisible or absent during daytime dives. Mandarin fish emerge at dusk from the rubble to perform their brief, luminescent mating displays — a spectacle reliably timed to 30 minutes before dark. The same bottom conceals mimic octopus, blue-ringed octopus, and tiger shrimp for divers willing to search the sand with a careful torch beam.
