About 70 percent of the Korean Peninsula is mountainous. Therefore, there are many beautiful mountains and Koreans love to flock there in the spring and fall. Most mountains have well-used paths and many people can be found hiking there each day.

  "San" means mountain in Korean. Most of the nation's mountains are branches of the Baekdu-daegan mountain range, which starts from Mt. Baekdu in North Korea and stretches down to Mt. Jiri in the South.

The best mountains to visit are Mt. Seorak on the east coast and Mt. Halla on Jejudo (Jeju Island) off the southwest coast, as well as Mt. Jiri in the southern part of the country.

One of the most famous mountains is Mt. Seorak, known in Korean as Seoraksan, a site most Koreans visit at least once in their lifetime. Seoraksan National Park in Gangwon-do (Gangwon Province) is located at the far northern end of the mountain and is known for its breathtaking valleys and waterfalls. Each spring, the park holds its annual flower festival, filling the air with sweet fragrances.

Another popular mountain, Mt. Halla, or Hallasan, is located on the island of Jejudo, about 80 kilometers south of the Korean peninsula. It is the highest mountain in South Korea and in 1970 became Hallasan National Park. Mt. Halla, a shield volcano, practically constitutes all of Jejudo, and it is famous for its beautiful scenery in all four seasons. There is a lake on top of the mountain called Baengnokdam, which means white deer lake. Many plants and animals that have been selected as national heritage items call this mountain home, and tourists can experience the beautiful diversity of nature there.
