One of the most significant celebrations is Pchum Ben, also known as Ancestors' Day, where Cambodians honor their ancestors through prayers and offerings.

- Boat rides: Despite the rain, September in Cambodia offers an excellent opportunity for outdoor adventures like boat tours in the Mekong River. You can also indulge in exhilarating water sports in Sihanoukville and Koh Rong with perfect water levels.
