Oishi Kougen is located in Kimino town and Aridagawa town, southeast of Wakayama city. You can enjoy panoramic view of Kii mountain range at the 800 m altitude. In autumn, comfortable breeze blows on you, and you can enjoy seeing Japanese susuki (pampas) grasses waving in the cozy breeze all around from mid September to mid November. Susuki grass shining in the sunset is marvelous! It takes about one hour to get there by car.
