Complete Guide to Ena Gorge Prefectural Natural Park (Gifu Prefecture): Four Seasons’ Charm, Highlights, and Access Information
Ena Gorge Prefectural Natural Park, located in Ena City, Gifu Prefecture, is a prefectural natural park known for its majestic scenery created by the grand flow of the Kiso River and towering cliffs. Named “Ena Gorge” by geographer Shigeataka Shiga in 1917, this site was created by the construction of the Oi Dam approximately 100 years ago. The artificial lake, combined with the bizarre rock formations lining both banks, creates a unique landscape beauty that continues to captivate many tourists.
History and Origins of Ena Gorge Prefectural Natural Park
The history of Ena Gorge Prefectural Natural Park dates back to the Taisho period. The artificial lake created by damming the Kiso River’s rapids at the Oi Dam was initially intended for power generation purposes. However, the beauty of the resulting landscape soon attracted attention and eventually developed into a tourist destination.
The construction of the Oi Dam held an important position in Japan’s power development history. The rising water level created by the dam exposed the unique landscape where cliffs and strange rock formations emerged from the water’s surface along the Kiso River. This scenic landscape caught the eye of geographer Shigeataka Shiga, who bestowed the name “Ena Gorge” upon it.
Following its designation as a prefectural natural park, development proceeded with both natural environment protection and tourism resource utilization in mind. In March 2020, the Ena Gorge Visitor Center and wooden decks were newly constructed, and the Momosuke Plaza was renovated, enhancing the facilities.
Topography and Natural Characteristics of Ena Gorge
Towering Cliffs and Bizarre Rock Formations
The greatest feature of Ena Gorge Prefectural Natural Park is the towering cliffs and uniquely shaped strange rock formations lining both banks of the Kiso River. These rock formations, shaped by long-term erosion, boast a sculptural beauty that can be called natural artwork.
Most notably famous is the “Umbrella Rock.” This rock, with its distinctive shape resembling an open umbrella, has become a symbolic landmark of Ena Gorge beloved by many tourists. The sight of Umbrella Rock viewed from the sightseeing boat is one of the highlights of Ena Gorge tourism.
Water Scenery of the Kiso River
The Kiso River, dammed by the Oi Dam, forms a calm lake surface. This artificial lake serves as a mirror reflecting the surrounding cliffs and forests, enhancing the scenic beauty of each season. The contrast between the calm lake surface and the geography retaining remnants of the former rapids creates Ena Gorge’s unique landscape.
Flora and Ecosystem
The Ena Gorge Prefectural Natural Park encompasses abundant plant life. In spring, approximately 200 cherry blossoms color the lakeside, while in autumn, Japanese maples and other maples display vibrant fall colors. Walking the footpaths within the park allows for observation of seasonal plants.
Additionally, rare plants designated as natural monuments grow naturally in this region, and the preservation of the natural environment is given high priority. The abundant vegetation serves as a habitat for diverse organisms including wild birds, making it a valuable area for nature observation.
Seasonal Charm and Highlights
Spring: Famous Cherry Blossom Destination

Autumn: Spectacular Autumn Foliage Viewpoint
Ena Gorge Prefectural Natural Park is most crowded with tourists during the fall foliage season. From early November to mid-November, Japanese maples and other maples vividly color the lake.
