The Orinduik Falls is located on the Ireng River in the Potaro-Siparuni Region of Guyana. It is at a point where the highland Ireng river thunders over steps and terraces of red jasper on the border of Guyana and Brazil before merging with the Takutu River and into Brazil to join the Amazon River.

The Orinduik Falls are situated amid the rolling, grass-covered hills at the edge of the Pakaraima Mountains and is a wide, multi-tiered series of cascades making it an ideal waterfall for swimming. The Waterfall is approximately 25 m tall and more than 150 m wide.

The name of the falls was said to be based on the Amerindian word for a type of native plant in the area.

Thanks to the airstrip next to the falls, Orinduik Falls is a popular tourist destination. There are frequent flights from Ogle Airport and Cheddi Jagan International Airport in Georgetown and most tours are combined with a trip to the Kaieteur Falls.
