Orroral Heritage Track

The tracking station, designated Station 21 in NASA's network, was selected in 1963 and became fully operational in May 1965. At its heart was a 26-metre parabolic antenna that received signals from orbiting satellites. The station's role evolved over its 20 years of operation to include support for crewed spaceflight programs. When it closed in 1985, the main antenna was relocated to Mount Pleasant Observatory in Tasmania, where it continues to operate. Today the ACT Heritage-listed site preserves the concrete foundations, equipment bases, and a suite of interpretive panels that explain the facility's place in the history of space exploration.

Interpretive signage along the track covers all three heritage layers: Ngunnawal traditional management of the Orroral Valley, pastoral settlement from the 1830s including droving routes through the high country, and the space tracking era. Views across the valley to the surrounding mountain ranges are wide and largely unobstructed, making this an excellent walk for photographers. Eastern grey kangaroos are commonly seen in the grasslands, and the Orroral River supports a range of birdlife.

Orroral Campground, the trailhead, is 19 km from the Namadgi Visitor Centre via Naas, Boboyan, and Orroral Roads, all sealed. The campground has toilets and basic facilities. As with all Namadgi tracks, dogs are not permitted and mobile coverage is absent. Visitors should check current conditions with the Namadgi Visitor Centre before departing.
