🌿 Explore the River Valleys and Sandstone Landscapes of Lower Portland

Discover the remarkable river landscapes of the Hawkesbury region in New South Wales with the Lower Portland 9031-2S Topographic Map, sourced from the official NSW Spatial Services Topographic Map Series.

Covering Lower Portland and the surrounding Hawkesbury River country north-west of Sydney, this detailed map provides valuable geographical information for bushwalkers, landowners, environmental professionals, surveyors, engineers and emergency services.

Situated at the confluence of the Hawkesbury and Colo rivers, Lower Portland occupies a distinctive landscape where broad waterways wind between steep sandstone hills, forested ridgelines and fertile river flats.

The region is particularly renowned for its dramatic river scenery, historic rural settlements and extensive protected bushland. The meeting of the Hawkesbury and Colo rivers creates one of the most recognisable geographical features in this part of the Hawkesbury Valley.

The surrounding countryside includes Lower Portland, the Colo River valley, riverfront properties, rural access roads and the sandstone landscapes associated with Parr State Conservation Area and Marramarra National Park.

The historic Lower Portland Ferry provides a crossing of the Hawkesbury River near its junction with the Colo, connecting communities and roads on opposite banks.

The area's combination of steep terrain, winding waterways, rural properties and isolated bushland makes detailed topographic mapping especially valuable for understanding landforms, drainage and access.

At a scale of 1:25,000 (1cm = 250 metres), the map reveals the landscape through detailed contour lines, waterways, roads, tracks, vegetation and natural features.

Whether you're exploring the Hawkesbury hinterland, investigating the Colo River catchment, planning rural property activities or undertaking professional fieldwork, the Lower Portland topographic map provides an excellent geographical reference.

Professionally printed by Mapworld and available in paper, waterproof DuPont™ Tyvek® and laminated finishes.
