The Samcheok King’s Cosmos Festival is held around late September to early October to attract more visitors who come to see autumn foliage at nearby tourism attractions such as Hwanseongul Cave, Daegeum Cave, Cheoneunsa Temple and more. The cosmos fields, spanning over 120,000㎡, along with sculptures made with flowers, are well-blended within a friendly farming area. The festival is one of the representative autumn festivals to enjoy autumn foliage. In addition, nearby attractions such as Jungyeongmyo Grave, Daegeumgul Cave and Hwanseongul Cave are famous as tourism attractions.
