From Seoul, I took the bus from the Dong Seoul Bus Terminal to Danyang for 19,800 won (S$24.73) and arrived at the Danyang Danuri Center. The bus trip is about 2 hours. Got a taxi for 4,000 won (S$5) to the Sono Moon Resort and stayed there for 3 days and 2 nights. You can also use the Korean T-card and take the local bus from the Danuri Center to the resort, it is about 4 bus stops. You can even walk from the Danyang Danuri Center and passed by the traditional market to reach the resort as it is just one straight road down, about 30 minutes of slow walk.
There is a water park inside the Sono Moon Resort but it was closed when I was there. There are also supermarket, bakery shop, restaurant and children play area at the basement of the resort. Worth staying for a few days.
The Mancheonha Skywalk is about 3 km from the Sono Moon Resort. Could take a slow morning walk.
The 30-metre high Manchenha Skywalk is free but you have to pay 3,000 won (S$3.75) for the bus to bring you up there. As the weather is not good, the other activities like the Alpine coaster and zipline were closed.
Took the local bus from the Danyang Danuri Center to Jacheon Station to take the train to Busan. The train ticket is 47,400 won (S$59.20) and the journey is about 2.5 hours.
The bento fast food was too good that I went to the same place 3 times.
