Sandstone Cliffs and Convict Road Country on the Hawkesbury

Overview

Dharug National Park stretches across rugged bushland on the north side of the Hawkesbury River, opposite Wisemans Ferry and about 55 kilometres from central Sydney. It covers 14,834 hectares of steep sandstone country, with cliff lines, gullies and sheltered creek flats shaping the character of the park.

This is part of the broad belt of sandstone parks around Sydney, and that setting gives Dharug a distinctly dry, rocky feel in some places and a more sheltered, leafy feel in others. The mix of landforms and habitats is one of the reasons the park feels bigger and more varied than the map first suggests.

Highlights

The scenery here is built around Hawkesbury sandstone. Long escarpments, deeply cut gullies and broken ridgelines give the park a strong sense of relief, especially where the country drops towards the river. The contrast between exposed ridges and tucked-away creek valleys is a big part of what makes the landscape memorable.

One of the defining features is the Old Great North Road, with a 16-kilometre section running through the park between Devines Hill and Ten Mile Hollow. Even without focusing on the track itself, that corridor adds a striking line through the sandstone country and helps frame some of Dharug’s best-known scenery.

Best Time to Visit

Autumn, winter and spring are usually the most comfortable times to appreciate Dharug National Park’s ridges, cliffs and bushland. The cooler months tend to suit this exposed sandstone landscape well, while spring also brings seasonal wildflowers. Summer can still be rewarding, but the dry, rocky terrain generally feels harsher in hot weather.

Plants and Animals

Dharug National Park protects a range of habitats rather than a single uniform bushland type, which helps explain the variety of wildlife found here. On the mountain slopes and through the bush you may come across gang-gang cockatoos, satin bowerbirds and green catbirds, while the park’s mix of gullies, ridges and creek areas supports broader biodiversity across the Sydney sandstone region.

After dark, the park is also known for gliding mammals including yellow-bellied gliders, greater gliders and sugar gliders. Seasonal wildflowers add another layer, especially in the more open sandstone country.

Culture and Heritage

Dharug National Park contains many Aboriginal sites as well as a substantial section of the Old Great North Road. That road was built between 1826 and 1836 using convict labour, and the surviving section through the park is part of the World Heritage-listed Australian Convict Sites. The combination of Aboriginal cultural places and early colonial road works gives the park a layered history that sits very visibly in the landscape.
