Probably one of the better known mountains in Geoje among the expat community, due to its ease of access and great views.
The most popular trailheads will be mentioned in the alternative routes below, but this post will focus on my usual route from “Aju proper”.
The trailhead starts behind the church which stands next to Hanulchae Apartments. There will be a short, but steep climb in which you'll emerge at a pagoda perched well above the highway tunnel.
Enjoy the view here before continuing to follow the path through the woods, eventually coming out onto a dirt utility road.
Follow the road until you reach a big grassy field with some exercise equipment. From here I suggest going to the top right side of the field and following the trail to Guksabong. Alternatively, you can follow the utility road and take a side path later, but I prefer to get as much trail time as possible.
You will come to a few different sets of crossroads, keep following the signs for Guksabong at each of them. You can always take a different route on the way back.
Once you've reached Guksabong, it's only another 0.6km to also hit-up Little Guksabong (작은 국사봉) as a secondary peak on this same mountain. You’ll see the signs heading to Little Guksabong behind the summit stone.
There are numerous paths that will take you to Guksabong, but perhaps the most well-traveled is the trailhead behind the Admiral Hotel in Okpo.
The trailhead behind Evervill Apartments in Aju is also a popular starting point.
