Discovery : Swallow Grotto (Yanzikou)
Discovery (Post#24) : Swallow Grotto (Yanzikou)
The name “Swallow Grotto” was after the swallows that are often seen in the area showing off their superb high-speed flying skills in the gorge. The specific kind of swallow that commonly found here is Pacific Swallows (Hirundo Tahitica). The marble cliffs that viewable in grotto has potholes created due long-term erosion made by Liwu River become a nesting place of swallows.
