The Kiso River at Ena Gorge is famous for its unique granite rock formations known as the 'Kiso-gahira', which were sculpted by natural erosion.
The Ena Ravine Large Bridge is a signature red steel arch bridge that contrasts sharply against the green foliage of the gorge.
The formation of the gorge was significantly altered by the construction of the Ohi Dam in 1924, which turned the river into a reservoir.
The site is positioned near the border of Ena and Nakatsugawa, acting as a historical gateway region between the Kiso Valley and the Mino Province.
The Ena Ravine Large Bridge Observation Deck provides an elevated vantage point overlooking the Ena Gorge, created by the damming of the Kiso River. The deck offers a direct perspective of the Ena Ravine Large Bridge, a distinctive red-arched structure that spans the river. The surrounding landscape features rugged, granite rock formations shaped by centuries of river erosion. This location serves as a primary point to observe the contrast between the engineered bridge and the natural watercourse. It is a secondary facility managed as part of local community infrastructure near the Kiso River waterway.
