Heisai National Park

The Heisai National Park [澤筌留编; へいさい・とうこう] is a national park located in the Tsuba Mountains, on the boundary between the prefectures of Heisai and Yamachi. It is one of the most beautiful national parks in the country and generally considered the best in the Zōku region. Along with encompassing much of the eastern side of the Tsuba range, it also consists of Heikan Forest, an expansive area of protected woodland.
Heisai National Park is popular with hikers, birdwatchers, nature enthusiasts and geologists. Its mountainous terrain, with steep valleys, rocky cliffs and coniferous groves, is both stark and beautiful.
