Hidden hiking trails near Seoul less crowded alternatives 2026

For travelers seeking solitude and nature without the overwhelming crowds of Bukhansan National Park, the best hidden hiking trails near Seoul are Ansan Jarak-gil (for accessibility), Achasan (for beginners and sunsets), Buramsan (for rock formations), and the backside of Inwangsan (for history). While Bukhansan draws over 5 million visitors annually, these alternatives offer spectacular city views, easier terrain, and a quieter atmosphere, often accessible within 30 to 45 minutes from central Seoul via subway.

The short answer: To escape the crowds, skip the main Bukhansan peaks and head to Ansan Jarak-gil for a barrier-free walk, Achasan for a 296m easy ridge hike, or Buramsan for a 508m moderate challenge with granite views.

Why You Should Look Beyond Bukhansan

Seoul is unique among global mega-cities because mountains cover approximately 25% of its total land area. While Bukhansan National Park is magnificent, it suffers from "over-tourism," especially on weekends. On a typical Saturday in spring or autumn, you may find yourself waiting in a queue just to reach the Baegundae Peak (836m).

For the international traveler, time is currency. Spending 3 hours in a queue diminishes the experience. The alternatives listed below not only save you time but offer a more intimate look at how locals enjoy their "Deungsan" (hiking) culture. These trails average a visitor density of 30-40% less than the major national parks, and most can be completed in under 3 hours, leaving you plenty of time to explore the city afterwards.

Ansan Jarak-gil: The Barrier-Free Wonder

Located in Seodaemun-gu, Ansan (295.9m) is often confused with Ansan City, but this mountain sits right in the heart of Seoul. It is the gold standard for accessible hiking in Korea. The "Jarak-gil" is a 7.0km raised wooden deck path that circles the entire mountain.

Why It's Special

The gradient here is kept below 9%, making it accessible for strollers, wheelchairs, and elderly hikers. It provides a dense forest experience with metasequoia trees that tower over 35 meters high. Unlike rugged trails, you can hike here in comfortable sneakers or walking shoes; heavy boots are unnecessary.

The Route and Views

The trail offers panoramic views of Inwangsan, Bukhansan, and the Blue House. The highlight is the Metasequoia Forest area, where you can rest on sunbeds installed by the district office. It is remarkably quiet compared to the chaotic trails of Northern Seoul.

If you are traveling with family or those with limited mobility, this is the definitive choice. For more details on accessible travel, check out our guide on accessible Seoul routes.

Achasan: The Best Sunset and Night Hike

Achasan (295.7m), located in eastern Seoul (Gwangjin-gu), is the local favorite for a casual hike. It is famous for being the first place to see the sunrise in Seoul, but savvy travelers know it as the best sunset spot. The trail is mostly dirt and rock, with fewer stairs than other Seoul mountains.

The Vibe

Achasan feels like a neighborhood hangout. You will see locals hiking with their dogs (on leashes) and friends sharing gimbap on the flat rocks. The elevation gain is gentle, making it perfect for beginners. From the trailhead to the ridge, it takes only about 30-40 minutes.

The Night View

Once you reach the ridge (Goguryeo Pavilions), you are treated to a stunning view of the Han River curving through the city, with the illuminated Lotte World Tower piercing the sky. The juxtaposition of the dark river and the bright city lights is mesmerizing.

Costs and Preparation

Hiking in Korea is a low-cost activity. Here is what you might spend for a hike at Achasan compared to a more commercialized tourist activity.

For snacks, stop by a convenience store near the station. You can find our recommendations in our guide to Korean convenience store food.

Inwangsan: The Hidden Route (Muak-dong Side)

Inwangsan (338m) has become Instagram-famous for its fortress wall views. However, the main trail from Gyeongbokgung Station is often packed with tourists. The secret is to approach from the Muak-dong side (Hongje Station).

The Alternative Path

Instead of fighting crowds on the fortress stairs, take the trail starting near the Muak-jae Skybridge. This side of the mountain features interesting rock formations like the "Seonbawi" (Zen Rock) and offers a mystical, shamanistic atmosphere before joining the main ridge.

The hike takes approximately 90 minutes round trip. The view from the top is identical regardless of which side you ascend—a 360-degree panorama of Seoul, N Seoul Tower, and the Blue House.

Buramsan: The Granite Giant

Located in Nowon-gu, Buramsan (508m) offers a completely different aesthetic. It is a "rock mountain" (Aksan), characterized by huge exposed granite slabs. It feels much higher and more rugged than its elevation suggests.

The Experience

Buramsan is less groomed than Ansan or Achasan. You will need proper footwear here—trail runners or hiking boots are recommended. The final ascent to the peak involves pulling yourself up using steel cables and rails (gloves are highly recommended, available at the trail entrance for ~₩2,000).

• Distance: Approx 5.5 km (Round trip)
• Calories Burned: ~600-700 kcal
• Transit: Sanggye Station (Line 4), Exit 1.

The view from the top is incredible. You can see the northern ridge of Bukhansan and Dobongsan in their full glory, without being inside the crowd.

Cheonggyesan: The Fitness Challenge

Cheonggyesan (582m) in Seocho-gu is the preferred mountain for Gangnam residents. It is known as the "Stairmaster" of Seoul mountains. If you want a serious cardio workout while traveling, this is the spot.

Maebong Peak

The most popular peak is Maebong (582.5m). From the Cheonggyesan Station (Shinbundang Line), the trail is relentlessly steep, consisting mostly of wooden stairs—over 1,500 of them. It is not a "leisurely walk," but a fitness destination.

The crowd here is different—lots of young professionals in premium activewear. It’s a great place to see the modern side of Seoul hiking culture.

Practical Hiking Guide for Foreigners

Hiking in Korea comes with its own set of unwritten rules and practical necessities. To blend in and stay safe, follow this guide.

Navigation Apps

Google Maps is unreliable for hiking trails in Korea. You must use Naver Map or KakaoMap.

1. Download Naver Map.
2. Set language to English.
3. Search for the mountain name (e.g., "Achasan").
4. Switch to "Hiking" layer (usually a mountain icon) to see the trail lines.

Gear and Etiquette

You don't need North Face gear from head to toe (though Koreans love it).

• Clothing: Breathable layers. Winters (Dec-Feb) are brutal—wear thermals. Summers (Jul-Aug) are humid—bring extra water.
• Greeting: If you make eye contact, a nod or a "An-nyeong-ha-se-yo" is polite.
• Right of Way: Hikers going up generally have the right of way.
• Music: Do not play music on speakers. Use headphones. This is a major complaint against tourists.

Best Seasons

• Spring (April-May): Azaleas on Achasan and Buramsan are pink and purple explosions.
• Autumn (October-November): Crisp air and fiery foliage.
• Winter (January): Clearest skies. You can see all the way to Incheon on a good day.
• Summer: Only hike early morning (before 8 AM) to avoid heatstroke.

Post-Hike Culture: The Essential Dualism

In Korea, the hike isn't over until you've eaten. The culture of Dwipuri (after-party) is essential. The standard menu is Makgeolli (rice wine) and Pajeon (green onion pancake) or Dubu-kimchi (tofu with sautéed kimchi).

For Achasan, head to the "Tofu Town" near the entrance. The soft tofu is made fresh daily and costs around ₩8,000-10,000 per serving. For Cheonggyesan, the area under the Wonteogol entrance is lined with outdoor seating restaurants.

Hoamsan: The Hidden Temple Route

Located in southern Seoul (Gwanak-gu), Hoamsan (393m) is technically part of the Gwanaksan range but functions as a separate, quieter entity. It is famous for the Hoapsa Temple.

The trail from Siheung-dong is gentle and features a "Deck Road" similar to Ansan, stretching about 2km. It leads to the temple, which offers a peaceful atmosphere and free vegetarian noodles (guksu) on Sundays around lunch time (donations appreciated).

The view looks out over Gwangmyeong and Geumcheon-gu, a different perspective from the Han River views of other mountains.

Conclusion: Which Trail is For You?

Choosing a trail depends on your energy level and what you want to see.

• For pure relaxation & accessibility: Ansan Jarak-gil.
• For sunset & beginners: Achasan.
• For adventure & views: Buramsan.
• For a workout: Cheonggyesan.
• For history & mystery: Inwangsan (Muak side).

By stepping off the beaten path of Bukhansan, you gain not just solitude, but a deeper connection to the local rhythm of Seoul. You see the city not as a tourist looking at a guide, but as a resident looking at their home.
