Tongyeong is a port town in South Korea that has recently become a hot resort destination. Some 7 million tourists visit annually, partly because of its delicious seafood. Freshly caught fish jump and splash with gleaming vitality at the fish market. The narrow streets and alleyways wind like a maze through the town, with an 80-year-old underwater tunnel adding a touch of exploratory adventure. On this walk, we meet the cheerful people of Tongyeong while enjoying the bracing smell of the sea.
