Shikoku Karst is one of Japan’s three largest karst landforms, an area of limestone that has been carved by erosion to create cone-shaped sinkholes (found along the Tengu Plateau and Jiyoshi Pass) and other geological formations. Trails wind throughout the park, offering visitors panoramic views of the surrounding green hills in spring and summer, silver grass in autumn, and snowy landscapes in winter. A stroll along forested paths offers therapeutic effects, and at night the high elevation away from city lights provides superb views of the starry sky.
