We took the KTX train to Busan for the weekend, which is a great way to travel around Korea. You can buy tickets online up to 30 days in advance, which we did.
We arrived in Busan around 1pm, and hopped on the subway to reach our hotel, the Busan Business Hotel near Seomyeon station. The hotel was fairly centrally located, and we were able to take the 1 or 2 line from Seomyeon to reach most of the places we wanted to go.
We headed out after checking in to our room and went to Centum City, a high-end shopping area featuring some beautiful buildings.
The Busan Cinema Center is there, which is home to the Busan International Film Festival, as well as a Shinsegae department store that is listed in the Guinness Book of World Records as the largest department store in the world.
We strolled along the river that leads into the ocean, enjoying the sea breezes and beautiful weather. We thought we would walk all the way to Gwangalli Beach and catch the subway there, but we ran out of time and grabbed a cab to take us to the nearest subway instead.
