Truk Lagoon - Operation Hailstone

Truk Lagoon Expedition 2010

Diving Truk Lagoon is the dream of many divers. But few realise that this is within the reach not only of rebreather and trimix divers. Many of the wrecks lie within recreational diving limits and enable divers with a reasonable level of confidence and experience to enjoy some of the World’s most incredible wrecks.

This trip is led by Leigh Bishop and Pete Mesley and is designed to cater for ALL levels of diving from advanced recreational divers to Trimix rebreathers, with wreck sites chosen to maximise the adventure for all participants.
