The Macal River is a river running through Cayo District in western Belize. Sites along the river include the ancient Mayan town of Cahal Pech and the Belize Botanic Gardens. The Macal River discharges into the Belize River. There are several tributaries to the Macal River including the following streams: Privassion, Rio On, Rio Frio, Mollejon and Cacao Camp.

Cahal Pech is a Maya site located near the town of San Ignacio in the Cayo District of Belize. The site was a palatial, hilltop home for an elite Maya family, and though the most major construction dates to the Classic period, evidence of continuous habitation has been dated to as far back as 1200 BCE during the Early Middle Formative period, making Cahal Pech one of the oldest recognizably Maya sites in Western Belize.
