🌿 4. Trail-by-Trail Breakdown – Namhansanseong Autumn Guide

① Jangsu Trail (3.8 km / 1 hr 20 min)

• Jeonseungmun (North Gate) -> Uikmun (West Gate) -> Secret Gates & Sueojangdae Pavilion -> Jihwamun (South Gate)

Course 1, the Jangsu Trail, is the most popular hiking route in Namhansanseong. It stretches about 3.8 km and takes roughly 1 hour and 20 minutes. The path is gentle and beginner-friendly, yet the military relics scattered along the way make the entire walk feel like stepping back into history.

As you follow the fortress wall, you’ll pass the North Gate (Jeonseungmun), the West Gate (Uikmun), and the South Gate (Jihwamun). Between these gates are secret side gates once used for urgent wartime communication, along with Sueojangdae Pavilion—the former command headquarters. Despite the short distance, the trail vividly reflects Joseon’s defensive system and military strategies.

For anyone wanting an easy walk where nature and history blend seamlessly, the Jangsu Trail is the perfect starting point for exploring Namhansanseong.

② King’s Trail (2.8 km / 1 hr)

• Sanseong Rotary-> Yeongwoljeon Pavilion -> Sungryeoljeon Pavilion -> Seomun (West Gate) -> Sueojangdae Pavilion -> Gukcheongsa Temple->Sanseong Rotary

The second route, “King’s Trail,” is about 2.8 km long and takes roughly one hour to complete. It’s the shortest of Namhansanseong’s five trails, but its story is far from light. This path is known as the route King Injo walked to surrender during the Qing invasion of Joseon, carrying the weight of the dynasty’s pain and difficult decisions.

As you follow the neatly maintained pine forest trail, the walls fade into the background and the forest becomes the main scenery, blocking out all traces of the city. In autumn, red foliage drapes over the fortress stones, and in winter, snow settles between the gates, creating a quiet, almost solemn landscape.

This short trail, with its heavy historical significance, often leaves the deepest impression. For those seeking a gentle walk or a moment of reflection in peaceful nature, the “King’s Trail” offers one of the most delicate and meaningful stories Namhansanseong has to share.

③ Monk-Soldiers’ Trail (5.7 km / 2 hrs)

• Namhansanseong World Heritage Center → Beolbong Peak → Janggyeongsa Temple → Mangwolsa Temple → East Gate → Jisudang → Namhansanseong World Heritage Center

If you want to experience Namhansanseong on a deeper level, try Course 3, “Monk-Soldiers’ Trail.” Stretching about 5.7 km and taking roughly 2 hours, this route goes beyond a simple hike—it follows the footsteps and spirit of the Joseon-era monk-soldiers.

Along the way, you’ll pass Janggyeongsa Temple and Bongamseong Fortress. Janggyeongsa served as a base where monk-soldiers stayed and carried out military duties during the Byeongja Horan (the Qing invasion of Joseon (1636), illustrating how Buddhist principles became intertwined with national defense.

Bongamseong, an outer defensive stronghold of Namhansanseong, is notable for its construction that takes full advantage of the mountain’s natural terrain.

④ Ongseong Trail (3.8 km / 1 hr 20 min)

• Sanseong Rotary → Namjangdae Site → East Gate → Jisudang → Gaewonsa Temple → Sanseong Rotary

Course 4, “Ongseong Trail,” is about 3.8 km long and takes roughly 1 hour and 20 minutes. As the name suggests, the highlight of this route is the South Ongseong—an outer defensive wall built in front of the main gate to block enemy attacks, showcasing the strategic military planning of the Joseon dynasty.

This trail blends fortress walls with forest paths, offering different scenery in every season. In autumn, the foliage colors the stone walls, while in winter, snow settles quietly over the gate, creating a serene and timeless atmosphere.

⑤ Fortress Trail (7.7 km / 3 hrs 20 min)

• East Gate → North Gate → West Gate → South Gate → back to the East Gate

The final Course 5, “Fortress Trail,” is the longest route in Namhansanseong, stretching about 7.7 km and taking roughly 3 hours and 20 minutes to complete. As you follow the fortress walls, the panoramic views of Seongnam, Hanam, and Gwangju change constantly, revealing why Namhansanseong is often called “the fortress made by the sky.”

Though it’s a long trek, this trail allows you to truly feel the full outline and scale of Namhansanseong. Once a strategic Joseon-era stronghold and now a UNESCO World Heritage Site, its grandeur is best experienced along this course.

💛 7. Namhansanseong History — Why UNESCO Recognized It

1) Built as Seoul’s Final Line of Defense

Namhansanseong was fully developed in 1624 during the reign of King Injo.
It was built for several strategic reasons:

• Joseon needed an emergency capital to protect Hanyang (Seoul).

• Military pressure from the Later Jin/early Qing was increasing.

• The state required a fortified city that combined fortress walls, a palace, temples, and military facilities.

As a result, Namhansanseong became the centerpiece of Joseon’s national defense strategy.
If Seoul was attacked, the king and government would retreat to this mountain fortress and continue leading the war.

In other words, Namhansanseong was not just a stone wall — it was the core of a national emergency system designed to safeguard the kingdom in times of crisi

2) Center of the 1636 Qing Invasion

King Injo resisted for 45 days inside the fortress.

• Haenggung (temporary palace)
• Ammun (Secret gates)
• Sueojangdae Command Pavilion
