What is Hanyang Doseong?
Seoul’s Ancient Guardian

Imagine the year 1396: the Joseon Dynasty is young, and King Taejo decides to fortify his new capital, Hanyang (old Seoul). Thus begins the construction of Hanyang Doseong Fortress, an 18.6-kilometer wall that wraps around Seoul’s four guardian mountains—Baegak (Bugak), Naksan, Namsan, and Inwangsan. These walls were more than defense structures; they marked boundaries, showcased royal authority, and cleverly followed natural ridges, blending seamlessly with the landscape.

Today, sections of the wall have been restored and are listed on UNESCO’s tentative heritage list, allowing modern visitors to time-travel on foot. The Myeongnyun 3-ga section sits along the Naksan Mountain Trail near Heunginjimun Gate (Dongdaemun or East Gate). Once a bustling entrance for merchants and travelers, the gate now offers a serene starting point. Nearby, Ihwa-dong’s colorful alleys and mural-filled streets create a bohemian contrast to the ancient stones.

Why is this section so special?

It’s the gateway to the Naksan stretch—famous for accessibility and breathtaking night views. Unlike Namsan Tower, it’s not overcrowded, yet it offers panoramic sights of the Han River, Lotte World Tower, and Seoul’s glittering skyline. Add the youthful vibes of nearby Hyehwa-dong with its theaters and cafes, and you’ve got a destination that’s both historic and trendy

Getting There: Easy Routes for First-Timers

Seoul’s public transport is a dream for travelers—clean, affordable (fares from 1,250 KRW), and highly efficient. The address (Myeongnyun 3-ga, San 2-11) lands you right in the Naksan area, easy to reach from major spots like Incheon Airport, Myeongdong, or Hongdae. Pro tip: Download Naver Maps or KakaoMap for real-time navigation in English.

From Incheon Airport:

Take AREX to Seoul Station → Line 1 to Dongdaemun History & Culture Park → Exit 1 → 5-minute walk to Heunginjimun Gate. (~1.5 hrs, 4,150 KRW)

From Myeongdong:

Line 4 to Hyehwa Station → Exit 4 → 10-minute walk east along Daesagwan-ro → Naksan-gil. (~20 mins, 1,250 KRW)

From Hongdae:

Line 2 to Sindorim → Line 1 to Dongdaemun → Exit 6 → 5-minute walk. (~25 mins). Or take Bus 6002 direct (~40 mins, 1,500 KRW).

Once there, look for the impressive Heunginjimun Gate. Just beyond it, the fortress wall climbs toward Naksan Park. Entry is free, with clear signage in English, Korean, and Chinese.

The Easy Trek: Walking the Naksan Mountain Trail

Walking the Naksan Mountain Trail

The entire fortress loop spans 18.6 km, but for most travelers, the Naksan Mountain Trail is the perfect introduction. This 2.1 km route runs from Hyehwa Gate to Heunginjimun Gate, weaving through Naksan Park.

Rated easy, it takes 1–1.5 hours with only 100m of elevation gain. Think of it as urban trekking with plenty of photo stops.

Step-by-step highlights

  1. Start at Heunginjimun Gate – Snap photos of the historic gate and follow the trail signs.
  2. Ihwa Village – Stroll through colorful murals, alleys, and cafes. Great for people-watching.
  3. Climb to Naksan Park – A gentle ascent with stone steps and panoramic viewpoints.
  4. Summit Views – From the observatory, soak in cityscapes by day or stay for sunset magic.
  5. Return Loop – Head back to the gate or extend to Dongdaemun’s lively shopping streets.

This short trek is accessible year-round, but spring blossoms and autumn foliage make it especially enchanting.

Sunset to Stars: Night Views You Can’t Miss

The real highlight here is sunset. As the sun dips behind Namsan, the sky shifts from orange and pink to deep violet. Then Seoul lights up. From Naksan Park, you’ll see the Han River shimmering like a ribbon, skyscrapers glowing in every direction, and the Lotte World Tower dominating the skyline.

Unlike crowded Namsan Tower, the fortress walls give you space and quiet. Bring a light picnic, sit on the stones, and watch the city transform. By 9 PM, the views are at their peak. Safety-wise, the area is well-lit and patrolled, making it great for solo travelers too.

Essential Prep: What to Bring

This is urban trekking, so no special gear needed—just comfort and a little planning:

  • Shoes: Comfortable sneakers with grip.
  • Snacks & Drinks: Reusable water bottle, convenience store kimbap, or an energy bar.
  • Clothing: Light jacket for evenings; hat/sunscreen for day.
  • Tech: Phone, charger, camera for those skyline shots.
  • Extras: Bug spray in summer, backpack, and a stamp book if you’re collecting fortress stamps.
