The name 'Myeongseongsan' translates to 'Crying Mountain,' originating from a local legend about the wailing of the King Gung-ye after his defeat.
The flame grass fields cover an area of approximately 150,000 square meters on the mountain's ridgeline.
The mountain was historically used as a military training area due to its proximity to the border zone, and parts of the trail remain within restricted access zones.
The grass species found here is Miscanthus sinensis, which turns a distinct silver-gold hue as it matures in October.
Myeongseongsan Mountain features an extensive alpine meadow covered in silver grass, known locally as eoksae, which occupies a large plateau near the summit. The site is a primary destination for the annual Myeongseongsan Silver Grass Festival, which typically occurs during the peak blooming period in autumn. Hikers access the area through multiple trails leading from Sanjeong Lake. The grass clusters span a significant portion of the ridge, creating a wide, open landscape contrasting with the surrounding forested peaks. The mountain elevation is approximately 923 meters, with the grass fields situated at a slightly lower plateau level. This location is part of the Gyeonggi-do regional trail network.

Wear sturdy, broken-in hiking boots as the trails contain loose rocks and uneven dirt paths.
Bring a windbreaker, as the open plateau area is significantly more exposed to high-altitude winds than the wooded base.
Carry sufficient water and snacks, as there are no vendor facilities once you reach the summit ridge.
Do not attempt the hike in casual footwear like sandals or loafers, and avoid scheduling the hike for rainy days as the paths become slippery.
The area is most accessible from late spring through late autumn; trails may be partially restricted during winter months due to ice.
Stick strictly to designated walking paths to prevent trampling the silver grass and protect the soil.
