The bus will leave on time so make sure you will board on time and stay around your bus platform. We find locker to store our bags and we found it not far from the locket, we asked people where the locker is. I took the small size and it cost KRW 2,000 for small size. There was also big size if you want to take the big size.
Since we didn’t want to do hiking at that time, we took cable car instead, from the entrance we just go straight, then on your left side, rushing to buy Cable Car ticket (KRW 10,000/round trip) because I heard it would be so crowded especially during peak season (summer vacation or fall foliage season). And well yeah, we got the boarding time for our Cable Car at 12.20 so we need to wait around 2 hours there. It only take 5 minute for one way to go up, and the capacity is 50 people.
And finally our time to get on board, we heading upstairs and take our cable car, the cable car getting up and up slowly but sure, 5 minutes ride though and you can enjoy the view from the top since the cable car window is clear and you can pampering your eyes to see lovely scenery.
