Welcome to the Ku-ring-gai GeoRegion, a large area of 440km²   just 40 minutes north of the Sydney CBD.

Fascinating rock formations, stunning viewpoints, coastal, forest and woodland walks with evolving geotrails allow visitors to view the natural and cultural history of an area that has developed over millennia.

Much of the natural bushland of the GeoRegion has been conserved within six protected areas. The largest being the Ku-ring-gai Chase National Park with other protected areas including Muogamarra Nature Reserve, and parts of Berowra Valley National Park, Lane Cove National Park, Garigal National Park and Long Reef Aquatic Reserve.

This website has been designed to provide you with the information you need to explore the GeoRegion, walk the geotrails, discover new vistas and learn about the formation of the area since the time of the early Jurassic period.
