The gardens range over 42 ha and there are more than 8 km of walking tracks, including a 1 km loop for visitors with limited mobility. The gardens are on Forestry NSW land that was logged about a century ago. The site was allocated for the botanic garden in 1987 and the visitor centre opened in 2001.

The Wallace Herbarium collects and records local species from the catchments of the Clyde, Deua and Tuross Rivers. The collection of more than 14 000 specimens has been registered with the National Herbarium database and is worked on by volunteers and an Honorary Curator.

There are picnic grounds, a sensory garden for children, a gift shop and café and public toilets. A free guided walk is conducted at 11.00am on the first Sunday of each month. The plant shop is stocked with plants propagated on site by volunteers and the funds are used to support the garden.

Open 9.00 am to 4.00 pm Wednesday – Sunday, and every day during NSW school holidays and public holidays (except Good Friday and 25 – 26 December). Admission is free.
