Marramarra National Park is a protected area in northern New South Wales on the outskirts of the Sydney metropolitan region. The park preserves rugged sandstone bushland, river valleys, and wooded ridgelines.

It offers remote bushwalking, riverine scenery and a network of tracks and fire trails rather than developed tourist infrastructure. The landscape includes Marramarra Creek and steep slopes with native eucalypt vegetation.

The park is part of the greater Sydney reserve system and is managed for conservation and low-impact recreation. Entrances and access points are located in the Hornsby and Hawkesbury areas, and much of the park is best reached by local roads and walking trails.

Marramarra National Park lies north of central Sydney in the Hornsby/Hawkesbury region, occupying steep terrain along the Marramarra River and adjacent valleys.

• Terrain and access: Mostly rugged sandstone country with creeks and ridgelines; facilities are limited and much of the park is accessed by walking tracks and unpaved roads.

The park is most dramatically reached by private boat or kayak via the Hawkesbury River from Brooklyn. Road access exists but often requires a high-clearance vehicle and a significant walk: follow signs toward Marramarra Creek and use local maps for trackheads.

• Access the park by water from Brooklyn (Hawkesbury River) for the most dramatic approach; private boat or kayak showcases cliff and estuary scenery.
• Bring a map and GPS: tracks are unmarked in many sections and the park is a maze of ridges and valleys.
• If hiking from the upper park entrances, use a high-clearance vehicle or be prepared for a long walk; some trails are best done with a local bushwalking group.
