South Korea’s national parks have long been valued for their breathtaking landscapes and ecological diversity. Spanning approximately 6.6% of the country’s total area, these parks predominantly encompass mountainous and coastal regions. Jirisan National Park, established in 1967, was the first national park designated and remains the largest mountain park in the country. Conversely, the smallest, Wolchulsan, covers only 56.1 km² yet boasts unique geological features. By 2016, South Korea had established 22 national parks, including four marine parks, primarily managed by the Korea National Park Service. Initially overseen by the Ministry of Construction, the parks’ administration transferred to the Ministry of Environment in 1998.
Reflecting the commitment to conservation, strict regulations have been implemented within these parks. While entry was initially free, most parks introduced admission fees in 1974, with only Gyeongju National Park currently exempt from charges. Due to rising tourism, visitor numbers and activities have been closely regulated to safeguard environmental integrity. Measures include restricting picnics and camping to designated areas, prohibiting night climbing, and implementing “natural rest” programs in areas of exceptional ecological value.

This series set is composed of only 6 stamps. But not bad impression. One of my favorite series stamps which can evoke my memory about the old and good days of philately.
