Tham Phung Chang is a cavern on Khao Chang or Chang Hill (in Thai means Elephant Hill) within Phang Nga Municipility. The cave has two entrances, one on the west and one on the east of the hill, inside Wat Tham Pung Chang.
The cave houses beautiful stalagmites and stalactites of various shapes, as well as contains sparkling calcite crystals on some parts of it’s wall. A stream flows through the cave all year round with deep water in some parts. The distance from one entrance to the other is approximately 1,200 metres.
According to legend, Yomdung, a wanderer, sought refuge at Chongdong’s house. The couple moved out of the house to establish their own family, earning living by farming. Towards the end of the harvest season, a herd of wild elephants trampled their crops.
Disappointed and infuriated, Yomdung got a spear and pursued the herd. He encountered an elephant that belonged to a man called ‘Ngum’, mistook it for for the one in the wild herd, speared the animal to death through it’s belly, gutted it an cooked the guts for food and lso cut the tusks – unaware of the animal’s innocence. he dead elephant became Chang Hill and the speared belly became ‘Tham Phung Chang’, the elephant belly’s cave.
