Pocheon Sanjeonghosu Lake (포천 산정호수)

Sanjeonghosu Lake is surrounded by the Myeongseongsan and Gwaneumsan Mountains. Its name refers to its location, like a well ("jeong") deep within the mountains ("san"). The lake was originally built as a water source for agriculture. It is circled by a 3 kilometer-long trail, and there is a silver grass habitat in the middle of a hiking trail leading to the summit of Myeongseongsan Mountain. Family-friendly facilities like snow sledding slopes and hot springs can also be found. Nearby tourist sites include the Hantangang River, Herb Island, Art Valley, and the Korea National Arboretum.
