Samseongsan was historically named after three monks—Wonhyo, Uisang, and Yunnil—who practiced Buddhism at Sammaksa temple on the mountain during the Silla dynasty.
The summit features a permanent flagpole displaying the South Korean flag, which is periodically replaced by local hiking volunteers due to weather wear.
The peak sits directly on the administrative boundary dividing Anyang-si in Gyeonggi Province and the Gwanak-gu district of Seoul.
Geologically, the mountain is dominated by Mesozoic biotite granite, resulting in large dome-like rock formations and exposed bedrock near the summit.
The ridge connecting Samseongsan and Gwanaksan forms a continuous hiking corridor spanning over 10 kilometers of rugged terrain.
Samseongsan Gukgibong is a prominent peak situated in Samseongsan, straddling Anyang in Gyeonggi-do and Seoul's Gwanak-gu district at an elevation of roughly 477 meters. The peak derives its name, meaning national flag peak, from the South Korean national flag permanently mounted at its summit. It offers panoramic views extending across the Anyang urban area, Gwanaksan mountain, and parts of Seoul. The surrounding terrain is characterized by rugged granite formations, steep hiking trails, and forested slopes covered in mixed deciduous trees. It serves as a popular destination for local hikers combining routes across the Samseongsan and Gwanaksan ridge network. The summit area features rocky outcroppings providing natural seating and wide viewing platforms. Several well-trodden dirt and stone paths ascend the mountain from the Manan-gu side in Anyang. The mountain is particularly busy during weekend mornings when hikers traverse its ridges.

Wear sturdy hiking boots with good grip due to the steep, slippery granite slabs near the summit.
Bring sufficient drinking water as there are no reliable kiosks or vending machines along the upper ridge trails.
Start your hike early in the morning to secure parking near the trailhead and avoid peak midday heat during summer.
Attempting the granite slab sections during or immediately after heavy rainfall when the rock surfaces become extremely hazardous.
Yield to uphill hikers on narrow staircases and granite paths, and carry all personal trash back down with you.
