Great for sightseeing. Plenty of islands around Tongyeong so be sure to visit early! Not easy getting around as only buses are available if you are on a budget.
People are friendly enough so don't be afraid to ask questions. If you want to visit Maemuldo, take the earliest ferry as it gets very crowded. Other recommended areas: Jangsado Sea Park (filming site of My Love From The Stars) and Mireuksan (go early or the cable car tickets will get sold out!).
traditional markets are good, island hopping can be considered, yet less information with foreign languages
