Tennyson Dunes

Tennyson Dunes is a protected coastal dune conservation reserve at Tennyson in the City of Charles Sturt, western Adelaide, South Australia. It preserves one of the last remaining intact pre-European dune systems along the Adelaide metropolitan coastline. The reserve features native coastal vegetation, undulating sand dunes and habitat for native birds and reptiles. Managed for conservation and low-impact recreation, it offers walking trails and interpretive signage highlighting its ecological importance.

Visitors can expect an open natural dune landscape directly behind Tennyson Beach, with undulating sand dunes stabilised by native coastal vegetation such as spinifex and acacias. A network of marked sandy walking trails and interpretive signs winds through the reserve, offering coastal views, opportunities for nature observation and birdwatching, and a quiet natural setting within a suburban coastal area. There are no built structures inside the dunes; the experience is low-impact nature walking.
