In the eastern part of Karatsu stands Mt. Kagami at 284 meters high. From the observation point at the top of the mountain, visitors can see a magnificent view of Niji no Matsubara, the Karatsu area and Karatsu Bay. Mt. Kagami is also a popular place to see cherry blossoms and azaleas. In spring, the 4 km road leading up to the peak becomes a tunnel of pink blossoms. All year round, visitors come to enjoy the observation tower, walking through the park’s mountain trails, and discovering rather scandalous monuments.
