From grassy woodlands on the lower eastern slopes of Deua Valley, to the peatlands and swamps on the tablelands, there are landscapes aplenty at Deua National Park. Valleys dissected by wild rivers, rugged mountains, deep gorges, dry ridges, steep escarpments, limestone karst and high plateaus are also some of the diverse landforms you'll find at Deua National Park. The Big Hole is thought to have been an underground cave until the ceiling collapsed and now is a 96m deep and 50m wide pit. Marble Arch has a car-sized boulder over its entrance and inside this cave are animal remains believed to be thousands of years old. Bendethera Cave is over 250m long, 320m wide and contains massive limestone formations in caverns with up to 15m high ceilings. Rocky outcrops found throughout the park support unique and rare species of gum trees, like the woila and jilliga ash, whilst the limestone slopes in Bendethera Valley is the only known location of Bendethera wattle; a sight to behold as they blossom during spring. The drier and cooler conditions allow pinkwoods and soft tree ferns to thrive in the higher altitudes of the eastern escarpments, and grey myrtle, lilly pilli and mock olives can regularly be seen along the small creeks and gullies throughout.

Deua is home to over 106 species of birds. There is a particularly high diversity of birds of prey in the park, such as the powerful owl and the peregrine falcon. The powerful owl is Australia's largest owl. The peregrine falcon, which is the fastest creature in the animal kingdom, can reach over 300km/hr in a high-speed dive when hunting. So if you see a dark vertical blur in the sky over Deua, you'll know now what it is and why it's moving so fast.

Passed on through generations in story and in song, the history of Aboriginal people of this land and their connection with all that surrounds them is very much a part of what you'll see in Deua National Park. Having travelled up and down the escarpment along well-worn pathways between the coast and the Monaro Tablelands for thousands of years, there are many places of spiritual significance. Scarred trees, grinding grooves and middens can be seen along the 'dreaming trails' of Deua.
