If you’re planning a trip to South Korea in 2025 and love nature, hiking, and breathtaking views, then you’re in for a real treat. South Korea is a land of mountainous terrain, where over 70% of the country is covered by mountains. These peaks aren’t just scenic backgrounds — they offer some of the most beautiful and accessible hiking trails in Asia. Whether you’re a beginner looking for an easy climb or an experienced hiker craving a challenging ascent, there’s a Korean mountain waiting to be explored.
In this article, we’ll take you on a journey through ten of the most stunning mountains in South Korea that you must hike in 2025. Each mountain has its own unique charm, history, and panoramic views that will leave you in awe.
1. Seoraksan
Located in Gangwon Province, Seoraksan is perhaps the most famous and beloved mountain in all of South Korea. It is part of the Seoraksan National Park, a UNESCO Biosphere Reserve known for its dramatic cliffs, lush forests, and seasonal beauty. In the fall, the mountain bursts into a fiery display of red, orange, and yellow foliage, attracting both domestic and international hikers. But Seoraksan is beautiful year-round — spring brings cherry blossoms, summer offers vibrant green trails, and winter turns the park into a snow-draped wonderland.
Seoraksan offers trails for all skill levels. If you’re new to hiking, you can enjoy the short trail to Biryong Falls or ride the cable car up to Gwongeumseong Fortress for sweeping views. More experienced hikers often take the Ulsanbawi Rock trail, which involves climbing over 800 steps to reach a panoramic viewpoint.
2. Jirisan
Jirisan is South Korea’s second-highest mountain and one of its most sacred. Spanning three provinces — South Jeolla, North Jeolla, and South Gyeongsang — Jirisan is part of the first national park ever designated in Korea. Known for its mystical energy and ancient temples, Jirisan offers a hiking experience that combines physical challenge with spiritual serenity.
The full traverse of Jirisan takes several days and is considered a rite of passage for serious Korean hikers. The trail from Nogodan to Cheonwangbong, the highest peak, is particularly rewarding. Along the way, you’ll pass old stone pagodas, mountain hermitages, and countless spots to pause and reflect. The sunrises here, especially from Cheonwangbong Peak, are legendary and well worth the early start.
3. Hallasan
If you’re visiting Jeju Island, Hallasan should be at the top of your list. This dormant volcano rises majestically from the center of the island and is the highest mountain in South Korea at 1,947 meters. Hallasan is a UNESCO World Heritage Site and offers an unforgettable hike through diverse ecosystems and volcanic landscapes.
There are two main trails to the summit: Seongpanak and Gwaneumsa. Both provide different views and experiences, but each leads to Baengnokdam Crater Lake at the peak, a mystical sight often shrouded in mist. Hallasan’s ever-changing weather and terrain make it a new adventure each time you climb it. In winter, the snow-covered peak offers a stark contrast to the usually warm and tropical island below.
4. Bukhansan
Right in the heart of Seoul lies Bukhansan, a mountain that offers a perfect escape from the city’s hustle and bustle. Despite its proximity to the capital, Bukhansan feels like a world away, with granite peaks, pine forests, and serene temples scattered throughout its slopes.
Bukhansan National Park is one of the most visited urban national parks in the world, and for good reason. The hike to Baegundae Peak, the highest point, is challenging but rewarding, offering panoramic views of Seoul’s sprawling skyline. Along the way, you’ll pass fortress walls dating back to the Joseon Dynasty, adding a historical layer to your hiking experience. Bukhansan is accessible, beautiful, and ideal for a day trip if you’re staying in Seoul.
5. Taebaeksan
Taebaeksan, located in Gangwon Province, is especially famous for its winter scenery. During the colder months, the mountain transforms into a snowy paradise, with frost-covered trees, glittering ice formations, and breathtaking sunrises.
Though Taebaeksan is not the tallest mountain in Korea, it holds a special place in Korean folklore and tradition. The trail to the summit is relatively moderate and well-maintained, making it a popular destination for hikers of all levels. One of the most popular times to visit is during the Taebaeksan Snow Festival in January, where giant snow sculptures and cultural events bring extra life to the mountain.
6. Songnisan
Nestled in North Chungcheong Province, Songnisan is part of the Sobaek mountain range and is famous for its scenic beauty and cultural significance. The name “Songnisan” means “remote from the ordinary world,” and it truly lives up to that title. The mountain is home to Beopjusa Temple, a historic Buddhist temple that dates back over 1,400 years.
The hiking trails here wind through peaceful forests filled with pine and maple trees. As you ascend, you’ll come across the Cheongdongmireukbul, a massive bronze Buddha statue that stands as a spiritual symbol of the mountain. The views from Munjangdae Peak, the highest point, are especially beautiful during the fall foliage season, making Songnisan a favorite among nature lovers.
7. Deogyusan
Deogyusan, located on the border of North Jeolla and South Gyeongsang provinces, is a majestic mountain with some of the best panoramic views in the country. It’s part of Deogyusan National Park and offers a well-developed network of hiking trails.
In winter, Deogyusan turns into a snowy dreamscape and is home to one of Korea’s top ski resorts, Muju. However, hiking Deogyusan is enjoyable in every season. Spring brings wildflowers, summer offers lush greenery, autumn dazzles with colorful leaves, and winter presents snowy trails and frozen waterfalls. The trail to Hyangjeokbong Peak is the most popular and takes you above the clouds on clear days, offering truly magical views.
8. Chiaksan
Chiaksan may not be as well-known as Seoraksan or Hallasan, but it’s a hidden gem located in Gangwon Province near the city of Wonju. It offers a peaceful and less crowded alternative for those looking to enjoy mountain scenery without the tourist crowds.
The trails here are known for their dense forests, rocky outcrops, and scenic streams. Guryongsa Temple, located near the entrance, adds a spiritual touch to the hike. As you ascend toward Birobong Peak, the highest point, you’ll encounter steep climbs and rope-assisted sections that add a sense of adventure. The panoramic view at the top is a rewarding end to a relatively challenging hike.
9. Woraksan
Woraksan is a mountain steeped in legend, located on the border of North Chungcheong and North Gyeongsang provinces. Its name means “Silencing the Roar,” referring to the mythical tale of a dragon whose cries were calmed by a monk’s prayer.
This mountain offers a variety of trails through dense forests and along high ridgelines. It’s particularly popular in the spring and fall, when the weather is mild and the views are at their most vibrant. At the summit, you’ll be greeted with views of Danyang and Chungju Lake, as well as a peaceful stillness that reflects the mountain’s mythical name. It’s a place where you can truly feel the quiet majesty of nature.
10. Gayasan
Last but certainly not least is Gayasan, located in North Gyeongsang Province. This mountain is best known as the home of Haeinsa Temple, one of Korea’s most important cultural landmarks. The temple houses the Tripitaka Koreana, a complete set of Buddhist scriptures carved onto over 80,000 wooden printing blocks. It’s a UNESCO World Heritage Site and a must-visit for anyone interested in Korea’s spiritual history.
The trails on Gayasan range from easy to moderately difficult, winding through thick forests and along rocky ridges. The views from the peak are breathtaking, but what sets this hike apart is the combination of natural beauty and profound history. Walking these trails feels like stepping back in time, surrounded by the echoes of centuries past.
Bottom line
South Korea is truly a hiker’s paradise. From volcanic peaks and ancient temples to snow-covered ridges and serene forests, the mountains of this beautiful country offer something for everyone. Whether you’re an experienced mountaineer or just starting out, hiking these ten mountains in 2025 will not only challenge your body but also feed your soul.
As always, when planning your hikes, make sure to check trail conditions, weather forecasts, and park regulations. Some trails require reservations, especially in national parks. And don’t forget to bring plenty of water, snacks, and a good camera — you’ll want to capture every moment.
