Seven Sisters and their Teacher is an amazing time lapse of South Korea taken in the Daejeon mountains. Much like the mountains of northern Seoul (Bukansan), the tranquil scenes of nature, temple and streams come together in autumn and explode with adventure in winter (recommended for visiting Bukansan, and that information follows). Enjoy your adventures in Korea.
Moxxor rep. Luke Goddard (company information) invited me on a great hiking location in northern Seoul, Mount Bukansan will not disappoint any travelers that wish to get some fresh air and outdoor activity in winter. They sell rubber-strapped steel crampons (5,000 won a pair) for walking on snow and ice -recommended for this mid-winter adventure. It's nice because those cramp-ons are all you need to climb safely, as you'll see in the video, I'm only wearing running shoes with the cramp-ons. The area is fresh and the scenery will enable a full eye-view of surrounding mountains and the winter is the preferred season, as it is clearer than summer months. If you come to Korea, make sure you try this!
Directions from Seoul: take the orange subway line northwest (Anguk Station...or others on Orange line 3) and take off at Gupabal station. From there, just take a bus with other local hikers and you'll get dropped off at the base of the mountains. From here you can hike to several peaks and there are several descents are optional, some end up on the northcentral area of Seoul at Miasamgeori Station, light blue line 4. Here's a subway map -this will help you find the way (click, it will take you to the original photo for printing).
