South Korea is widely known for its vibrant cities, rich cultural heritage, and delicious cuisine. Yet beyond the urban landscapes lies another side of the country filled with rugged mountains, dense forests, and dramatic coastlines. With more than twenty protected parks across the peninsula, South Korea offers some of the most beautiful natural scenery in East Asia.
Many of the country’s most iconic landscapes are preserved within national parks, where visitors can hike through granite peaks, discover hidden temples, and enjoy spectacular seasonal scenery. In spring, forests bloom with flowers and fresh greenery. Autumn transforms the mountains into brilliant displays of red and gold foliage, while winter brings snow-covered landscapes that feel peaceful and remote.
Several national parks are easily accessible from major cities such as Seoul, making them ideal for both day trips and longer adventures. Others are located in more remote regions, where visitors can experience untouched wilderness and traditional mountain culture.

Seoraksan National Park – South Korea’s Most Famous Mountain Park
Located in the northeastern part of the country, Seoraksan National Park is often considered the most spectacular national park in South Korea. The park is famous for its dramatic granite peaks, forested valleys, and ancient temples hidden among the mountains.
Visitors can explore a network of hiking trails that range from gentle walks to challenging mountain climbs. One of the most rewarding hikes leads to Ulsanbawi Rock, where panoramic views reveal the rugged landscape of the surrounding peaks.
Another highlight of the park is Sinheungsa Temple, a historic Buddhist temple located at the entrance to the mountains. The temple’s peaceful atmosphere and traditional architecture provide a fascinating contrast to the dramatic natural scenery.
Autumn is the most popular time to visit Seoraksan National Park. During this season, the forests explode with vibrant fall colors, attracting travelers from across South Korea and beyond.
Hallasan National Park – Hiking South Korea’s Highest Mountain
Located on Jeju Island, Hallasan National Park protects the tallest mountain in South Korea. Rising more than 1,900 meters above sea level, Hallasan is a massive shield volcano that dominates the island’s landscape.
Several hiking trails lead toward the summit, offering travelers the opportunity to experience a wide range of ecosystems. As hikers climb higher, they pass through forests, alpine meadows, and volcanic landscapes before reaching the crater lake at the top of the mountain.
The summit views are spectacular, especially on clear days when the surrounding island and ocean become visible in the distance. Because of its volcanic origins, the terrain here is very different from mainland mountain parks.
Hallasan National Park is one of the most rewarding destinations for outdoor enthusiasts visiting Jeju Island. The combination of scenic hiking routes, unique geology, and breathtaking views makes it a highlight of any trip to the island.
Jirisan National Park – Korea’s Largest National Park
Jirisan National Park is the largest and one of the oldest national parks in South Korea. Located in the southern part of the peninsula, the park covers an enormous area of mountains, valleys, and forests.
The park is especially popular among hikers because of its extensive trail network. The most famous route leads to the summit of Cheonwangbong Peak, the highest point of Jirisan. Reaching the summit requires a long hike, but the views across the surrounding mountain ranges make the effort worthwhile.
Jirisan is also home to several historic temples, including Hwaeomsa Temple, which dates back more than a thousand years. These temples offer peaceful places to rest and reflect while exploring the mountains.
Because of its vast size and natural beauty, Jirisan National Park provides one of the most immersive wilderness experiences in South Korea.
Bukhansan National Park – Mountain Hiking Near Seoul
For travelers staying in Seoul, Bukhansan National Park offers one of the most accessible outdoor escapes in the country. Located just north of the capital, the park features granite peaks, forest trails, and scenic viewpoints overlooking the city.
Despite its proximity to Seoul, Bukhansan feels surprisingly wild. Hikers can climb rugged trails that lead to spectacular rock formations and panoramic mountain vistas. One of the most famous viewpoints is Baegundae Peak, the highest point in the park.
The park is particularly popular with locals on weekends, when residents of Seoul head into the mountains to enjoy fresh air and exercise. For visitors, it provides a convenient opportunity to experience Korea’s natural landscapes without traveling far from the city.

Odaesan National Park – Peaceful Forests and Ancient Temples
Located in Gangwon Province, Odaesan National Park is known for its peaceful forests, scenic mountain trails, and historic Buddhist temples. Compared with some of the country’s more famous parks, Odaesan offers a quieter atmosphere where visitors can enjoy nature without large crowds.
One of the most important cultural landmarks in the park is Woljeongsa Temple, a historic temple surrounded by tall fir trees. The path leading to the temple, lined with centuries-old trees, is one of the most beautiful walks in South Korea.
Odaesan is also home to Sangwonsa Temple, another historic monastery located higher in the mountains. Many visitors combine hiking with temple visits, creating a journey that blends nature with cultural heritage.
During winter, Odaesan becomes especially magical when snow covers the forest and temple roofs. This peaceful landscape offers a very different experience from the busy cities of South Korea.
Taeanhaean National Park – Coastal Landscapes and Hidden Beaches
Unlike many of South Korea’s mountain parks, Taeanhaean National Park protects a dramatic stretch of coastline along the Yellow Sea. Located on the western side of the peninsula, the park features sandy beaches, rocky cliffs, and scenic coastal trails.
Visitors can explore numerous beaches scattered along the coastline. Some of the most beautiful include Mallipo Beach and Kkotji Beach, both known for their wide sandy shores and stunning sunsets.
Taeanhaean National Park is also famous for its coastal hiking routes. Walking paths wind along the cliffs, offering spectacular views of the sea and nearby islands.
