Jeju Island, a volcanic wonder in South Korea, is crowned by Hallasan Mountain—a towering natural icon that dominates the island’s skyline. Rising 1,947 meters above sea level, it is the tallest peak in South Korea and a sacred site with deep cultural and ecological significance. For nature lovers, hikers, and those seeking a unique travel experience, Hallasan offers more than just altitude. It invites visitors into a vibrant world shaped by millennia of volcanic activity and enriched by Korea’s diverse flora and fauna.
A Sleeping Giant Shaped by Fire and Time
Hallasan is a shield volcano, formed from eruptions long ago that left behind a broad, sloping mountain covered with lava flows and crater lakes. Although dormant, its dramatic terrain and crater-shaped summit hint at a fiery past. Locally known as “Yeongjusan,” or “the mountain so high it can pull the stars,” Hallasan has been revered for centuries. The surrounding area was designated as Hallasan National Park in 1970, a move that helped preserve its unique geological formations and ecosystems.
The mountain is surrounded by 368 small volcanic cones called “oreum” in Jeju dialect. These satellite cones pepper the landscape, forming gentle rises and small craters that extend across the island. This network of oreum adds to the region’s surreal, otherworldly feel—perfect for curious hikers and photographers alike.
Hallasan Mountain’s Vertical Ecosystem and Biodiversity
One of Hallasan’s most fascinating features is its vertical biodiversity. As you ascend the mountain, you move through a variety of climatic zones, from subtropical vegetation at the base to subalpine plants near the summit. This natural layering creates an ecological tapestry rarely seen elsewhere in Korea. Scientists have recorded over 1,800 plant species and 4,000 animal species, including more than 3,000 types of insects.
Spring and summer bring a riot of wildflowers, while autumn transforms the trails into a fiery canvas of red and gold foliage. Winter, however, unveils Hallasan in its most majestic state: snow-covered, silent, and serene—like a Korean Mt. Fuji. The changing seasons make every visit feel like a new adventure.
Best Hallasan Mountain Hiking Trails by Difficulty
Exploring Hallasan is easy thanks to a well-maintained network of hiking trails. While the summit itself is only accessible via two main routes, multiple paths across the national park offer stunning views and a variety of hiking experiences.
- Seongpanak Trail – 9.6 km (One way)
The most popular route to the summit, this path offers a moderate climb through forests and volcanic rock formations. It takes about 4.5 to 5 hours to reach the top. - Gwaneumsa Trail – 8.7 km (One way)
More challenging than Seongpanak, this trail is steeper but provides dramatic landscapes and panoramic views of the crater at the summit. - Eoseungsaengak Trail – 1.3 km
A short hike that’s ideal for beginners. You won’t reach the summit, but you’ll enjoy views of nearby oreum and Jeju’s coastline. - Yeongsil Trail – 3.7 km
Known for its dramatic cliffs and autumn foliage, this trail offers mid-level difficulty and rewarding scenery. - Donnaeko Trail – Temporarily closed or limited access depending on weather and maintenance.
Before hiking, it’s wise to check the park’s website or visitor center for trail conditions, weather alerts, and opening hours. The summit trails have specific cutoff times—early starts are essential.

Hallasan is more than a mountain—it’s the spiritual backbone of Jeju Island. Traditional myths say gods once lived on its summit, and many local rituals still honor the mountain’s guardian spirit. The nearby Jeju Stone Park and Seongeup Folk Village offer insight into the island’s culture, while the volcanic landscapes surrounding Hallasan are UNESCO-designated biosphere reserves.
