Rising majestically above the sprawling metropolis of Seoul, Bukhansan National Park serves as the literal and metaphorical "lungs" of South Korea’s capital. Among its many jagged peaks and forested ridges, Baegundae Peak stands as the ultimate prize. Reaching an elevation of 836.5 metres, it is the highest point in the park and the entire city, offering a 360-degree panorama that juxtaposes ancient granite wilderness with the shimmering glass towers of one of the world’s most densely populated urban centres. The hike to Baegundae is not merely a physical challenge; it is a cultural rite of passage for locals and a breathtaking introduction to the Korean peninsula's rugged topography for international visitors. This 8.3-kilometre return journey takes hikers through historic fortress gates, past serene Buddhist temples, and up steep, wire-rope-assisted granite slabs that demand both respect and steady footing. It is a landscape defined by its dramatic white granite peaks—Baegundae, Insubong, and Mangnyeongdae—which together earned the area the historic name Samkak-san, or "Three-Horned Mountain." Whether you are seeking a spiritual escape from the city's neon glow or a rigorous alpine workout, the ascent to Baegundae Peak delivers an experience that is uniquely and profoundly Korean.
Bukhansan National Park holds a Guinness World Record for being the "Most Visited National Park per Unit Area," and nowhere is this popularity more evident than on the trail to Baegundae Peak. Despite the crowds, the experience remains essential. The trail is a masterclass in vertical progression, transitioning from the lush, deciduous forests of the lower valleys to the exposed, wind-swept granite heights of the summit. The terrain is predominantly rocky, consisting of well-maintained stone stairs, dirt paths interwoven with tree roots, and the final, exhilarating scramble over massive granite slabs where steel cables provide the only handholds against the steep incline.
The hike typically begins at the Bukhansanseong Visitor Centre, the most popular gateway. From here, the path follows a mountain stream, passing through the historic Bukhansanseong Fortress walls—a defensive structure originally built to protect the capital during the Joseon Dynasty. As you ascend, the forest canopy provides welcome shade, but the gradient is relentless. The final 500 metres of the climb are the most dramatic; the trees disappear, replaced by smooth, pale granite that glows under the sun. Here, hikers must use fixed wire ropes to pull themselves up the steep rock faces. It is a section that tests your nerves but rewards you with increasingly vast views of the surrounding peaks, including the sheer, vertical face of Insubong, a world-famous destination for rock climbers.
At the summit, a small, flat area marked by a South Korean flag offers a vantage point like no other. To the south, the entire city of Seoul unfolds—the Han River winding through the centre, the Lotte World Tower piercing the horizon, and the dense clusters of apartment blocks stretching toward the sea. To the north, on a clear day, the mountains of North Korea are visible across the demilitarised zone. The atmosphere at the top is often celebratory, with hikers sharing snacks and taking photos at the summit stone. The descent requires careful footwork, particularly on the granite sections, but the sense of accomplishment upon returning to the valley floor is immense. This is a hike that captures the spirit of Seoul: a city that refuses to be separated from the wild, ancient mountains that birthed it.
The history of Bukhansan is inextricably linked to the history of Korea itself. For centuries, these mountains have been regarded as sacred protectors of the capital. The name "Bukhansan" literally translates to "Mountains North of the Han River," and their strategic importance led to the construction of the Bukhansanseong Fortress. While the original fortifications date back to the Baekje Kingdom (132 BC), the massive stone walls and gates seen today were largely reconstructed in 1711 during the Joseon Dynasty under King Sukjong. This was a response to the devastating invasions by the Japanese and Manchus, intended to provide a mountain refuge for the royal family in times of war.
The fortress wall stretches for 12.7 kilometres along the ridges of the park, connecting the major peaks. As you hike toward Baegundae, you will pass through several of the original gates, such as Daegumun (Great North Gate), which served as vital checkpoints for centuries. These stones have witnessed the rise and fall of dynasties, the Japanese occupation, and the Korean War. Even today, the mountain remains a site of spiritual significance, home to dozens of Buddhist temples and hermitages. It is common to hear the rhythmic sound of temple bells or the chanting of monks echoing through the valleys as you climb.
Culturally, hiking is more than just exercise in South Korea; it is a national pastime and a social ritual. You will notice hikers of all ages, often dressed in high-end, colourful technical gear, regardless of the trail's difficulty. This "hiking culture" includes a deep respect for the mountain and a tradition of sharing food at the summit. It is not unusual for a stranger to offer you a slice of frozen pear, a piece of dried squid, or a cup of hot ginger tea. Understanding this cultural backdrop—the blend of military history, Buddhist spirituality, and modern social tradition—enriches the hike, making it a journey through the Korean soul as much as a trek through its geography.

Bukhansan undergoes a dramatic transformation with each season, and the experience of climbing Baegundae varies significantly depending on when you visit. The weather in Seoul is temperate but experiences extremes, with hot, humid summers and cold, dry winters.
Spring (April–May): This is arguably the most beautiful time to visit. The mountain wakes up with a burst of colour as cherry blossoms, azaleas, and forsythia bloom along the lower slopes. The temperatures are mild (15–22°C), making the steep climb comfortable. However, spring also brings "Hwangsa" (Yellow Dust) from the Gobi Desert, which can occasionally obscure views and affect air quality. It is wise to check the fine dust (PM2.5) levels before heading out.
Autumn (September–October): Autumn is the peak season for hiking in Korea. The humidity of summer vanishes, replaced by crisp, clear air and exceptionally blue skies. The foliage turns into a spectacular tapestry of crimson, orange, and gold, usually peaking in mid-to-late October. Because the weather is stable and the scenery is world-class, the trails can become extremely crowded, especially on weekends. If visiting in autumn, a weekday hike is strongly recommended.
Summer (June–August): Summer is challenging due to high humidity and temperatures often exceeding 30°C. The "Jangma" (monsoon season) typically occurs in July, bringing heavy rains that can make the granite slabs dangerously slippery. If hiking in summer, start as early as possible (06:00) to avoid the midday heat and carry significantly more water than you think you need. The lush green canopy provides shade, but the air remains heavy.
Winter (November–March): Winter transforms Bukhansan into a stark, monochrome landscape of white granite and dark pines. While beautiful, it is the most dangerous season. The granite slabs on the final ascent to Baegundae often glaze over with ice, making them impassable without crampons (spikes). Temperatures can drop to -15°C at the summit with significant wind chill. Only experienced hikers with proper winter gear should attempt the summit during these months.

Important Notes:
Bukhansan is a high-intensity day hike that requires a moderate to high level of cardiovascular fitness. While the distance is relatively short (8.3 km), the elevation gain of 840 metres occurs over a short horizontal distance, meaning the gradient is steep. Preparation should focus on leg strength and balance for the rocky sections. No formal bookings are required to enter the park or hike the peak, but logistics regarding transport and timing are crucial.
The most common base for this hike is anywhere in central Seoul. To reach the Bukhansanseong trailhead, take Subway Line 3 to Gupabal Station. From Exit 1, take Bus 704 or 34 and get off at the "Bukhansanseong Entrance" stop. The bus ride takes about 20 minutes. If you prefer the Ui-dong entrance (shorter but steeper), take the Ui-Sinseol Light Rail to the terminal station (Bukhansan Ui Station). Taxis are also readily available and affordable from most parts of northern Seoul.
This is a day hike requiring no overnight accommodation. Camping is strictly prohibited within Bukhansan National Park to protect the environment and prevent forest fires. There are no mountain huts or lodges available for public overnight stays on the Baegundae route.
Nearby Accommodation:
One of the greatest advantages of Bukhansan National Park is its accessibility. Currently, no permits are required for individual hikers to climb Baegundae Peak. Entry to the park is free of charge, as the national park entry fees were abolished in South Korea in 2007 to encourage public health and outdoor recreation.
Important Considerations:
Parking: If you choose to drive, there are paid parking lots at the Bukhansanseong and Ui-dong entrances. However, these fill up by 07:30 AM on weekends. Public transport is much more reliable and recommended.

Pre-Departure Checks:
Granite Hazards: The primary safety concern on Baegundae is the granite. When dry, it offers incredible friction. However, when wet or covered in a thin layer of dust or ice, it becomes incredibly slippery. If it begins to rain while you are on the upper sections, descend immediately and with extreme caution. Use the steel cables at all times on the summit ridge; do not attempt to "free climb" the slabs away from the safety railings.
Crowd Management: On weekends, the sheer number of people can be a safety hazard. Queues form at the narrow cable sections. Be patient, do not push, and allow descending hikers the right of way in steep sections. Watch out for "hiking poles" from other hikers, which can be accidentally poked toward you in crowded areas.
Dehydration and Exhaustion: The climb is deceptively steep. Many hikers underestimate the effort required and do not bring enough water. Heatstroke is a genuine risk in July and August. If you feel dizzy or excessively fatigued, stop in the shade and rest. There are mountain rescue posts at major junctions, and the "119" emergency number works throughout the park.
Wildlife: While there are no dangerous large predators, be mindful of the mountain cats and magpies at the summit; they can be aggressive if they smell food. Wild boars exist in the park but are rarely seen on the high, rocky trails; if you encounter one, do not run—back away slowly and avoid eye contact.
Emergency Contact: Dial 119 for emergency services. Most trail signs have a "location number" (e.g., Bukhansan 01-04). Note these down as you pass them; they are vital for rescuers to find you in a park with hundreds of kilometres of trails.
Insubong Viewpoint: As you approach the summit of Baegundae, you will have a front-row seat to Insubong (810 m). This giant granite dome is a sheer vertical wall and is the birthplace of modern rock climbing in Korea. Watching the tiny specks of climbers navigating the "Insubong Face" is a highlight of the trip. The contrast between the hikers on Baegundae and the technical climbers on Insubong is striking.
Bukhansanseong Fortress Walls: Don't just walk past the walls—take a moment to examine the masonry. You can see the difference between the original 18th-century stones (weathered and irregular) and the modern restoration work. Walking along the ridge top allows you to follow the wall as it snakes over the jagged topography, a testament to the incredible engineering of the Joseon era.
The "Face Rock": Located near the final ascent, this natural rock formation looks remarkably like a human profile staring out over the city. It is a popular spot for a quick photo and a reminder of the strange and beautiful shapes that wind and water erosion have carved into the granite over millions of years.
Baegunbong-ammun (Secret Gate): This is the highest gate in the fortress. Unlike the grand main gates, this "ammun" (secret gate) was designed to be inconspicuous, used for moving supplies or messengers in and out of the fortress during a siege. Its narrow, dark passage provides a cool blast of air even on the hottest days.
Mangnyeongdae: The third of the "Three Horns," this peak is less visited than Baegundae but offers a fantastic perspective of the summit you just climbed. It requires more technical scrambling and is often quieter, providing a moment of solitude in an otherwise busy park.
Bukhansan National Park is a precious ecological island in a sea of concrete. With millions of visitors annually, the impact on the environment is significant. Following Leave No Trace principles is not just a suggestion; it is essential for the park's survival.
Your responsibility as a walker:
By walking mindfully, you ensure that the "Granite Crown of Seoul" remains a pristine escape for the generations of hikers who will follow in your footsteps.
