Gapsa Temple

 Located in the west valley of Yonchonbong Peak of the Mt. Kyeryong Nat'l Park range, 19 km from Gongju, Gapsa Temple is said to have been built by
Adohwasang of the Koguryo Kingdom in 420.  
This temple, one of the 10 biggest temples of the Hwaom Order, contains numerous cultural assets. The autumn foliage along the trail starting from the temple, running up to the 845m high peak of Mt. Kyeryong and further down to Donghaksa Temple, which is on the opposite side of the mountain, is remarkable.
This 5.4 km-long trail has a smooth slope and is a perfect family hiking course.  Even during the hot summer days, one can feel cool walking along the deep Gapsa Valley, with Yongmun Waterfall and Shinhung Hermitage on the way.
