Northern Valleys

The Northern Valleys includes the magnificent sandstone valleys of the Capertee and Wolgan (west of the range) and Macdonald, Grose and Colo Valleys in the east.

The region is dominated by large tracts of World Heritage National Park with relatively small areas of settlement including productive agriculture, hobby farms and lifestyle blocks.

Many of the region's waterways have wild and scenic values and offer some of the best water quality in the Hawkesbury Nepean catchment. The Colo River alone provides 50% of the freshwater flows vital to health of the Hawkesbury estuary.

The Northern Region is an important area for biodiversity in the catchment and includes endangered species such as the Regent Honeyeater.
