Located in the precious natural forests in Osaka Prefecture, the park is the western starting point of the Tokai Natural Trail. Visitors can enjoy seasonal changes in the scenery, such as the cherry blossoms in spring, the trees covered with ice and hanging icicles in winter, and especially the brilliantly colored leaves late in fall.

The Mino Insect Museum, which is located on the way to the waterfall, is also well known. Here at this museum, visitors can see not only about 10,000 samples of insects, but also over 500 live butterflies of about 10 to 15 species and learn about their year-round ecology.Approximately 10 to 15 species and over 500 animals.
