Oryukdo Skywalk

This guide to Oryukdo Skywalk in Busan opens with a question sailors have argued for centuries: are there five islands out there, or six? It follows Kim Heung-soo, who took a job most people would run from in 1990 as a lighthouse keeper on a bare islet, then transferred to the outermost island's tiny lighthouse and never left. You'll hear about the night in October 2016 when Typhoon Chaba sent a wave more than fifty meters high crashing over his tower, smashing his living quarters, and how he rode it out behind an iron door he had welded on himself. Stand on the glass thirty-seven meters above the water, over the same rocks Kim has watched every night of his working life.
