Korea has world-class hiking on volcanic peaks and granite mountains, an Olympic-standard ski area, and a network of coastal and island trails. Here is the complete outdoor activity picture.
South Korea is a small country with an extraordinary density of outdoor experiences. 70 percent of the peninsula is mountainous, and the national park system protects the finest landscapes. The combination of easily accessible mountains from Seoul, a ski area that hosted the Winter Olympics, and the island landscapes of Jeju makes Korea genuinely compelling for active travellers.
Hiking – The Finest Mountains
Hallasan, Jeju Island
South Korea’s highest peak is at 1,950 metres on the volcanic island of Jeju. The Seongpanak trail (9.6 kilometres one way) ascends through montane forest to the Baengnokdam crater lake at the summit, one of the finest mountain views in Korea. Requires advance permit reservation. See the full Hallasan hiking guide for trail options, permit booking, and what to bring.
Seoraksan National Park, Gangwon Province
Korea’s most dramatic mountain landscape. The Ulsanbawi Rock trail is the most popular summit route, offering extraordinary views of the granite peak over the autumn maple forest (early October is the finest window). The Daecheongbong summit trail requires a reservation and is a full-day commitment. See the Seoraksan hiking guide for the full trail breakdown.
Bukhansan National Park, Seoul
A national park directly bordering Seoul’s northern city limits, accessible by subway. Multiple trails from easy ridge walks to technical scrambles with city views. The Dobong and Uisangbong trails are the most popular. 30 minutes from central Seoul to the trailheads by subway.

Skiing – PyeongChang Olympic Area
Korea’s ski season runs from December through March in the mountains of Gangwon Province. The PyeongChang area (host of the 2018 Winter Olympics ) has three main resorts: Alpensia, Yongpyong, and High1. All operate to international standards, with good beginner and intermediate terrain. A full day, including lift pass and equipment rental costs, costs around 80,000 to 120,000 won.
Access from Seoul: KTX to Jinbu Station (about 2 hours), then shuttle bus. The winter festivals in the surrounding area make January and February genuinely festive beyond the skiing itself. The Korea winter festivals guide covers the ice fishing festivals in Hwacheon and PyeongChang, which run alongside the ski season.
Day Trips from Seoul for Outdoor Experiences
The Gyeonggi Province day trips guide covers the best outdoor options within 1 to 2 hours of Seoul:
- Suwon Hwaseong Fortress: UNESCO fortress wall walk (5.7 kilometres). 50 minutes from Seoul by subway.
- Nami Island: A river island with famous tree avenues, spectacular in autumn. 70 minutes from Seoul by train.
- Bukhansan National Park: Mountain hiking from the city limit. 30 minutes by subway from central Seoul.
Busan Coastal Hiking
The Galmaet-gil coastal trail connects Busan’s beaches, headlands, and fishing villages along the southern coast. Multiple sections from easy waterfront walks to more challenging cliff-top paths. The Igidae Coastal Trail (4.7 kilometres) along the dramatic rocky coast east of Gwangalli Beach is the finest section.
Busan also has excellent day-trip options for active travellers: Gyeongju (ancient mountain temples and Namsan hiking), Tongyeong (island boat trips through a national marine park), and the routes covered in the Busan day-trip guide.
Jeju Olle Trail
A 425-kilometre coastal hiking trail around Jeju Island in 26 sections. Each section takes 4 to 6 hours and covers coastal cliffs, lava fields, fishing villages, and forest paths. The full trial takes 3 to 4 weeks. Individual sections are excellent day hikes accessible without having to complete the full route. The Udo Island and Seongsan sections are the most scenic.
