Introducing Mary River Region
Bird Billabong, just off the highway a few kilometres before Mary River Crossing, is a back-flow billabong, filled by creeks flowing off the nearby Mt Bundy Hill during the Wet. It's 4km off the highway and accessible by 2WD year-round. The scenic loop walk (4.5km, two hours) passes through tropical woodlands, with a backdrop of Mt Bundy granite rocks.
About another 2km along the same road is the emerald-green Mary River Billabong, with a BBQ area (no camping). From here the 4WD-only Hardies Track leads deeper into the national park to Corroboree Billabong (25km) and Couzens Lookout (37km).
Further along and north of the Arnhem Hwy, the partly sealed Point Stuart Rd leads to a number of riverside viewing platforms and to Shady Camp. The causeway barrage here, which stops freshwater flowing into saltwater, creates the ideal feeding environment for barramundi, and the ideal fishing environment.
