Stayed at Lotte City Hotel which was few blocks away from the stream (the end of it...). The stream is quite long so there are many choices hotel-wise, but like others said it's difficult to recommend without knowing budget. Lotte City Hotel worked out great because it's extremely close to metro, Myeongdong, and restaurants by the stream.

Hi - I don't know about a lantern festival. The stream and walkways, including bridges and stepping stones, looks nice at night because of the lighting along the pathways.

Hello, Yes, it's a long fun walk. My son and I did a lot of walking but cannot tell you how long it took us to finish it because we weren't counting, Yes, you will reach this market and can do your shopping and eat too. However, it's better to go early because, by late afternoon, there will not be a big crowd. Have fun.

Yes you can!

Yes, Nov 2-4, 2018.

Apparently so, Nov.2nd til Nov.18th.

Hi, Yes. This is a stream flowing. Free to walk along and breathe.

The lights festival is only during autumn.

Very safe. Enjoy the walk.

I took Exit 5 of Jongak metro station. Walk down the road for a few minutes and you will reach the stream. Turn right to walk along the stream, best at night between 7 to 8 pm. You can walk down to the stream and you go under a stone bridge. The waterfall can be seen straight ahead. This is perhaps the best way to see the waterfall.
