A government statement said the price of single-day tickets will rise from USD 20 currently to USD 37. A three-day pass will cost USD 62, up from USD 40. The price of a 7-day ticket, valid over a one-month period, will go up from USD 60 to USD 72.
No explanation was given for the increase. The government said USD 2 from each ticket sold will be donated to a Swiss-owned children's hospital, Kantha Bopha, which provides free treatment.
A UNESCO World Heritage site, Angkor is a symbol of national pride that is emblazoned on the Cambodian flag.
Last month, Apsara Authority, which oversees the archaeological complex, said that beginning this month local and foreign tourists who dress immodestly will not be allowed to enter.
