I will be in Seoul in mid June and I'm wondering if there are any easy hike with good sunrise view at the end? By easy, I mean can reach the top within an hour of hike. It needs to be accessible by public transport too. I saw that Bukaksan is beautiful but not sure how long it will take. Also, is it safe to hike alone in the dark in Seoul?

Appreciate any suggestions that fit my requirements above.
