Liansin Pond Waterfall (中文版： 連心池瀑布) is a small pond and waterfall in Yunlin, Gukeng Township. It's next to Youlong Lake Trail (游龍湖步道) and there is also a path to the larger Penglai Waterfall (蓬萊瀑布) which is about 1.5km downstream.
The Youlong Lake Trail is a short (~1km, 20 minutes round trip) hiking trail. "Lake" is a metaphor for forest, there is small creek, but no actual lake there.
Liansin Pond Waterfall is only a short (5 minute) hike from the parking area. There is a small lake and waterfall, which is great for swimming in.
Above the waterfall there are two heart-shaped pools linked together ("連心" means "heart chain") which is where the area gets its name.
