History
Hang Dong Canyon used to be an abandoned field and was accidentally created by Mr. Chatkarin Trakulinsan, the land owner. Between 2004-2005, Trakulinsan sold soil and created a 50-meter (160 ft) deep hole, around 48,000 square meters (520,000 sq ft); this hole eventually turned into a canyon. 10 years later, the hole was filled with water becoming a gigantic pond surrounded by the canyon.[citation needed]
