Bat Cave Waterfall (蝙蝠洞瀑布) is a beautiful bowl-shaped waterfall in Tainan, Nanxi District. It's easy to get to, with no hiking or river tracing required. The pool is deep, and great for swimming. Next to the waterfall are some small caves, but when I went there were no bats.
This waterfall dries up during the winter.
