The Azalea Festival is held from April to May, when 100,000 azaleas color the mountain slope in vermilion. The view of the Kujuku Islands, which represent the landscape of Saikai National Park, is spread out underneath and is genuinely superb. There is a 100-meter-long roller slide, plenty of playground equipment, and a visitor center where visitors can eat, so you can enjoy the park with your family.
