Gizo and Western Province are the Solomon Islands at their most cinematic: WWII aircraft in clear lagoons, the Toa Maru wreck near Gizo, sharky walls at Munda and Uepi, and rainforest islands where boat transfers double as wildlife watching. The trip is usually built from land-based hubs such as Gizo, Munda or Uepi Island Resort, but liveaboards also route through Western Province, so it works as a hybrid destination. Expect remote logistics, cash-heavy travel, warm water, local reef ownership and highly skilled operators rather than a resort strip. The best broad window is May to October for drier, more comfortable weather, while diving itself is credible year-round when boats can run.
