In 2026, hiking in Korea has evolved from a local pastime into a global trend known as "K-Hiking." With over 70% of the Korean peninsula covered in mountainous terrain, it’s no wonder that trekking is the national sport. Whether you are looking for a quick urban escape or a multi-day wilderness adventure, the best mountains in Korea offer something for every skill level.
South Korea’s hiking infrastructure is world-class, featuring well-maintained trails, clear signage in multiple languages, and unique cultural experiences like mountain temples and "Makgeolli" (rice wine) sessions after a descent. Let's dive into the ultimate guide to the peaks you cannot miss this year.
Bukhansan: Seoul's Majestic Backyard
If you have limited time in Seoul, Bukhansan National Park is non-negotiable. Holding the Guinness World Record for the "Most Visited National Park per Unit Area," it is easily accessible via the Seoul subway system. The most popular peak, Baegundae (836m), offers a panoramic 360-degree view of the metropolitan skyline juxtaposed with jagged granite cliffs.
Top Trail: Baegundae Peak Course
The trail starts from the Bukhansanseong Fortress Entrance. It is a challenging 2-3 hour ascent that involves some steep rock climbing assisted by steel cables. According to the Korea National Park Service, spring and autumn are the peak seasons for visibility and temperature.
Seoraksan: The Crown Jewel of the East
Located in the Gangwon-do province, Seoraksan is widely considered the most beautiful mountain in Korea. It is famous for its vibrant autumn foliage and the dramatic Ulsanbawi Rock formation. In 2026, the park has introduced new eco-friendly trekking zones to preserve its UNESCO Biosphere Reserve status.
Ulsanbawi Rock vs. Daecheongbong
For a moderate hike, the Ulsanbawi trail offers a rewarding view of the East Sea. For hardcore hikers, the ascent to Daecheongbong (1,708m), the highest peak, requires an early start and significant physical stamina. It's often paired with a visit to the historic Sinheungsa Temple.
Hallasan: Climbing Korea's Highest Peak
Sitting at the heart of Jeju Island, Hallasan (1,950m) is a shield volcano and the tallest mountain in South Korea. The trails here are unique because they pass through various climate zones, from subtropical to alpine. The reward at the top is the Baengnokdam, a stunning crater lake.
Reservation System in 2026
To prevent over-tourism, a reservation is mandatory for the Seongpanak and Gwaneumsa trails. You must book your slot months in advance through the Jeju Hallasan Reservation System. This is a crucial step for 2026 travelers.
Jirisan: The Vast Wilderness
Jirisan is the first and largest national park in Korea. It spans three provinces and is known for its rugged beauty and spiritual significance. Unlike the granite-heavy mountains of the north, Jirisan offers rolling ridges and deep, lush valleys.
| Mountain | Difficulty | Highlight | Best Time |
|---|---|---|---|
| Bukhansan | Moderate | City Skyline | All Year |
| Seoraksan | Hard | Granite Cliffs | October (Autumn) |
| Hallasan | Moderate-Hard | Crater Lake | May (Azaleas) |
| Jirisan | Very Hard | Sunrises | Summer/Autumn |
Understanding K-Hiking Culture & Etiquette
Hiking in Korea is a social event. You will see groups of hikers in high-end, colorful technical gear—this is part of the fun! To blend in and stay safe, follow these 2026 etiquette rules:

- Leave No Trace: Garbage bins are non-existent on trails. Carry all your trash back down.
- No Loud Music: Respect the silence of nature; use headphones if you must listen to music.
