The twenty-kilometer ride took over an hour to complete, and we were dropped off in a dusty town with one store and three people. Now, just an easy mile-long hike separated us from the crystal blue water and white sand of Casuarina Beach. On arriving, we were overjoyed — exactly as we had hoped for! A gorgeous stretch of sand extending for kilometers along the northern coast of the island, bordered by the shrubby Casuarina trees which lend the beach its name. We decided to escape local bathers, and walk towards the lighthouse on the northwestern tip of the island before sitting down: a plan that would be our undoing.
