【San'inkaigan National Park】
Recommended for summer.
The San'inkaigan National Park comprises approx. 75 km of coastline stretching from Kyotango City, Kyoto Prefecture, in the west to Tottori City, Tottori Prefecture. The coastline is a ria coast (submergent coast) where the mountains connect to the ocean; it is characterized by its richly varying coastal landscape comprising landforms of sea cliffs, sea caves, and reefs that have developed significantly and merge with the ocean area. Another characteristic is the expansive sand dune landscape, represented by the Tottori Sand Dunes, that have been formed through wave erosion and by sand carried from river mouths. In this way, unique landforms can be seen throughout the national park, and because these landforms comprise various types of rocks, the park is also referred to as the "Geological Park" or "Beautiful Rock Park."
With the San'inkaigan National Park at its center, the San'inkaigan Geopark was admitted into the Global Geoparks Network in 2010, recognizing the global importance also of the San'inkaigan Coastline.

San'in Kaigan Geopark is a place where visitors can learn while enjoying how the Sea of Japan was formed and how today's landscapes came to be. Beyond simply viewing beautiful scenery, visitors can discover the stories behind nature—how different rocks create different coastal shapes, how sand dunes are formed, and how local communities have lived with the sea for generations.

The geopark offers guided geo-tours, coastal trails, and hands-on craft activities that appeal to both children and adults. These experiences help visitors understand nature more deeply and enjoy it more fully. In 2010, the geopark was recognized as a member of the Global Geoparks Network, highlighting its international significance.
