Buka passage

A particular highlight in Buka is the Buka passage, which refers to the channel that separates Buka Island from Bougainville Island. The water runs at about 6 knots when the tide is fast, making deep undulations on the water's surface. Riding in a banana boat in Buka Passage is a buzz. Banana boats congregate near the animated market and the passage is abuzz with these small crafts plying between the town and Kokopau village (opposite Buka on Bougainville Island).

A word of warning: avoid snorkelling in Buka Passage; you could wind up lost at sea because of the current, and the boat traffic on the surface is pretty intense.
