Immerse yourself in the everyday life of the locals during this half-day adventure to a trio of Busan's most popular sites beginning with a tour of Gamcheon Culture Village. Founded by Korean War refugees in the 1950s, the village was built on such a steep mountain-side slope, that it's been nicknamed the "Machu Picchu of Busan." Admire the colorful houses adorned with artistic touches like birds and dragonflies as you follow your guide through the labyrinthine alleyways, perhaps stopping at the Sky Garden for the best views. Another sight to behold is the Songdo Sky Walk. Curved like a dragon, the 1,190-foot-long promenade extends out from the edge of Songdo Beach. Your final stop is the landmark Ja-Gal-Ch'I Market, Korea's largest seafood market and Gukje Market, filled with souvenirs.
