Overview

There are five islands to visit in How to Fish. The Lighthouse, Forest, Desert, Rocks and Volcano Islands.

You begin at the Lighthouse and unlock each new island by completing an NPC quest, defeating the main boss and returning its important drop. Once you receive the coordinates, the next island will appear as a coloured marker on your Radar.
