Day trip · A fortress in the forest
Namhansanseong남한산성
Twelve kilometres of ramparts on a wooded ridge, an hour from the centre. A proper walk, a painful piece of history, and one of the finest night views over Seoul.

A little history
In 1636 the Manchus invaded Korea. King Injo took refuge here with his court and thirteen thousand soldiers. After forty-seven days under siege, in midwinter and without food, he came out to kowtow before the enemy emperor. The episode remains one of the great humiliations of Korean history — and the fortress, never taken by assault, a symbol of resistance.
The site has been on the UNESCO list since 2014. It is also a lived-in village, known to Seoulites for its braised-chicken restaurants.
The places
Sueojangdae command post
수어장대A two-storey pavilion at the highest point of the walls. It is the goal of most walks.

West Gate
서문 · 우익문The smallest gate, the one the king walked out of to surrender. Right beside it, a platform looks over all of Seoul: this is the place for sunset and the city lights.

Haenggung Palace
남한산성 행궁The temporary palace where the king lived through the siege, rebuilt in the 2000s. Small entry fee.

The walking loops
The short loop
South Gate, Sueojangdae, West Gate, North Gate, back to the village: about four kilometres, an hour and a half, little climbing. This is the one to do.
The full circuit
All four gates and the whole ridge: seven to eight kilometres, three to four hours, with a few steep stretches on the east side.
From the bottom
Strong walkers climb on foot from Sanseong station in about an hour instead of taking the bus.
Getting there
Subway then bus
Line 8 to Sanseong station, exit 2, then bus 9 or 52 to the terminus inside the fortress. About twenty minutes uphill; at weekends the buses are full.
From Gangnam
Allow about an hour door to door. It is the quickest trip on this list.
Good to know
Go in the evening
The advice nobody follows: go up in the late afternoon, walk the short loop, and be at the West Gate for sunset. Bring a torch for the walk back to the village.
Eating
Dakbaeksuk — a whole chicken simmered with medicinal herbs — is ordered for two to four people. Mountain-vegetable pancakes and herb bibimbap are the lighter option.
Autumn
In late October and early November the fortress maples are superb — and the site very busy at weekends.
Winter
The walls under snow are magnificent, but the stone steps turn slippery. Light crampons sell for a few thousand won in convenience stores.
