Birrigai Time Trail

The Birrigai Time Trail is a 1.2 km interpretive walking trail in Tidbinbilla Nature Reserve, about 40 km southwest of Canberra city centre. It leads to the Birrigai rock shelter, the oldest known Aboriginal occupation site in the Australian Capital Territory with evidence dating back 21,000 years. The trail uses signage and landscape to interpret Aboriginal history and connection to Country.

Visitors can expect a short, signposted loop walk through open eucalypt forest and grassland leading to the Birrigai rock shelter. The trail features interpretive panels explaining 21,000 years of Aboriginal occupation, seasonal use, and archaeological findings. The shelter itself is viewed from a protected platform behind a barrier. The setting is natural bushland within Tidbinbilla Nature Reserve with opportunities for nature observation and photography.
