Monga National Park, National park in New South Wales, Australia

Monga National Park is a 251.44-square-kilometre national park in southern New South Wales, about 230 kilometres south-west of Sydney and roughly 10 kilometres south-east of Braidwood. It protects high-altitude eucalyptus forest and temperate rainforest, and its elevation is 686 metres.

The Corn Trail, a restored bridle path from the 1830s, shaped early travel through the region by connecting coastal plains to the tablelands. This historical route still winds through the dense forest today, marking paths that were important during the colonial period.

Monga National Park holds cultural sites of the Yuin and Walbunja Aboriginal peoples, whose country takes in this part of southern New South Wales. These places are part of an ongoing attachment to the land rather than traces of a vanished past, and they are best visited with that in mind.

The park lies about 230 km southwest of Sydney and roughly 10 km southeast of Braidwood, the nearest town. The Corn Trail, a bridle track built in the 1830s, has been restored and reopened as a walking track through the forest.

The park is home to rare Southern Sassafras and Pinkwood trees growing as hemiepiphytes on Soft Tree Ferns. This unusual growth pattern is a sign of the complex layers that make up the rainforest ecosystem here.
