this is a steep climb and it sent at consistently 8% (with some sections a bit above). but there is a nice 2 hour hike at the top to Obongson mountain, and the road is in good shape, very quiet, with a climbing lane for the climber.

in order to get off, there's some very steep grades on the road, but once you get onto the gravel it's pretty consistently two to 3%. very quiet and in decent shape as of writing this (2024)

Old Passroad with not many traffic. Steep climb up to 14%. Great view on top to the Ocean and great decent

Another short but fairly steep climb with an average gradient of 10.5% over 1km. There’s no pretence here it’s pretty straight up and only major variance is a sweeping right hand curve over the top, where there is a pull section and marker stone with the name of the hill. Lovely fast descent greets you on the other side, at the bottom there is a crossroads, here you will find a couple of shops - which are a popular rest stop, or if you turn left and go a bit further down the road there is the 솥비카페 - coffee shot if you are in need of a caffeine fix.

This one slowly winds its way to the top over 1.6km and an average gradient of 7%, a pleasant slow burner to the classic bridge/tunnel top completion. There are walls of green on either side, but signs of huge new motorway under construction in the valley below. Nice quick, quiet descent greets you out the otherside.
