Mount Imlay National Park, Nature reserve in Bega Valley, Australia.

Mount Imlay National Park is a nature reserve spanning 48 square kilometers with eucalyptus forests, rocky ridges, and deep gullies near Eden, New South Wales. The landscape features varied vegetation and geological formations shaped by erosion and forest growth over time.

The park is named after the Imlay brothers, early pioneers of the district. The mountain itself is called Balawan by the Bidwell and Yuin peoples and holds great importance in their culture and spiritual teachings. The park was created to protect this area, which includes rare plants like the Imlay mallee and Imlay boronia near the summit.

The mountain is called Balawan by the Bidwell and Yuin peoples, for whom it carries central importance in their culture and spiritual teachings. The park itself takes its English name from the Imlay brothers, early pioneers of the district. The two naming layers sit side by side on the same peak.

Access is via a side road off the Princes Highway south of Eden, on the park's eastern side. The mountain is also known as Balawan to the Bidwell and Yuin peoples. Much of the park is eucalyptus forest, with a 2-hectare rainforest remnant in a fire-free gully.

The two-hectare rainforest remnant in a fire-free gully is dominated by Black Olive Berry trees (Elaeocarpus holopetalus), a cool-temperate pocket unlike the surrounding eucalyptus forest. The rare plants Imlay mallee and Imlay boronia grow near the summit of Mount Imlay.
