My sister-in-law recommended we visit Nami Island via public transport from Seoul (over 1.5 hours to 2 hours or more to travel). As we had two teenagers travelling with us, we decided to take the easy route by booking a day tour instead (around £50 each person, along with these two other locations: Gangchon Rail Bike and Italian Village & Petite France). Therefore, we didn’t need to look out for trains, platforms, exits and walking in the hot sun!
