Upon reaching the narrow valley entrance, you’re welcomed by an astonishing sense of openness. It’s hard to imagine that such a canyon landscape exists right beside a silted-up reservoir. The mudstone consists of alternating layers of sandstone and shale, carved by the river into a narrow valley about 200 meters long and 20 meters deep. At the end lies a slender waterfall, and this landscape is estimated to be around 3 million years old.It’s important to note that the terrain of Earth Valley is fragile, with frequent falling rocks and the constant risk of collapse, so lingering for too long is not advised.

Earth Valley is located on the Fanzipeng Stream upstream of the Nanhua Reservoir. It was once a popular attraction in Tainan many years ago but gradually faded into obscurity after the reservoir was built. It was later rediscovered by chance, bringing this hidden gem back into the spotlight.
