A fascinating ancient natural attraction, Fa Hien Caves, locally known as Pahiyangala, takes you back to the prehistoric times of Sri Lanka. It is said to believe that these caves were the home to a Chinese monk who arrived in Sri Lanka, presumably more than 30,000 years ago. All visitors to Fa Hien Caves can observe the remains of the ancient eras, which certainly is an invaluable treasure trove of Sri Lankan history.
