Explore the majestic “Forest of Water,” home to over 200 roaring waterfalls

Located at the foot of Mt. Ontake is Osaka-cho, an area blessed with over 216 waterfalls that are over 5 meters tall. Experience the majestic nature here up close and personal with a choice of 14 different hiking trails. Generally, the use of a certified guide is required, however, there are some routes that can be experienced on your own.

In Gandate Park, one can gaze up at an enormous 72-meter-tall, 120-meter-wide stone cliff that was created by hardened lava from a Mt. Ontake eruption 54,000 years ago. The area is famous for autumn colors and is designated as one of the Top 33 Spots for Autumn Color Viewing in Hida and Mino. The humongous stone cliff and surrounding orange mountainsides are nothing short of breathtaking.

During the average year, peak autumn-color viewing season is from late October to early November.

※Many of the courses here pass through national forest lands and require a Mountain Entry Permit (meaning they are off limits to unregistered visits).
