9 nights and 7.5 days diving Milne Bay and the southern islands of Conflict Islands and the Engineer Islands on the refurbished Spirit of Niugini. Lower deck cabins $2645 USD per person sharing, main deck cabins $3600 USD pp sharing.
This itinerary has an excellent combination of pelagic dive sites with schooling barracudas, jacks, reef sharks, surgeonfish, batfish and more; amazing corals, both soft and hard, untouched by bleaching, fantastic macro with more cool critters than I can list here, including bargibanti and denise pygmy seahorses, wunderpus, mimic octopus, numerous frogfish species, lacy scorpionfish (Rhinopias aphanes), shrimps galore, and also the famous "walking" epaulette sharks (Milne Bay and Papuan); and manta cleaning stations. We will also have a couple of trips ashore.
Ties in with the superb Goroka Highlands Cultural Festival before hand.
