Gapsa Course 1 - Gyeryongsan National Park is a 4.7 mile moderately trafficked out and back trail located near the city of Gongju-si that features a waterfall and is rated as difficult. The trail is primarily used for hiking and is accessible year-round.
This course stretches from Gapsa Parking Lot to Gapsa Temple and the top of Sambulbong Peak The trail is goes through Orisup Forest from Gapsa Parking Lot to Gapsa Temple. Its a big temple built more than 1,000 years ago. Visitors are given a chance to see ancient historical and cultural resources such as Gapsa Dongjong, Gapsa Budo, Cheoldanggan, and Jiju. Gapsa Temple is famous for its beautiful autumn tint. Visit this course in autumn, and you will see colorful leaves that can be called a great gift of nature.
I completed this hike a couple of days ago with my two boys, ages 12 and 11. We completed the hike all the way to the peak which is about a 2000 ft elevation gain. The hike is difficult but very doable with a well marked and maintained trail the entire way. I would highly recommend this trail as it offers great diversity from forest to peaks and cultural temple sights along the way. We didn't have proper winter gear which made it a bit difficult and slippery near the top but by March it should be clear i would think.
