Bombo Headland Quarry Geological Site, Nature reserve and geological site in Kiama, Australia
Bombo Headland Quarry is a coastal headland with exposed basalt columns and latite rock formations from different geological periods. The isolated pillars rise from the shoreline and show layers that formed millions of years ago.
The site was worked as a quarry from the 1880s through the early 1900s, extracting materials that helped build nearby towns. Mining activity shaped the landscape that is now recognized as a geological site.
The name comes from a nearby Aboriginal community and reflects the long connection between the landscape and the region. Today, visitors see the raw basalt columns that shape the coastline and make the geological story tangible.
The site sits along Princes Highway and is always open, but wear sturdy shoes for uneven ground. Coastal weather and tides change conditions quickly, especially during high tide or storms.
The rock formations contain fragments from depths of about 80 kilometers and come from Late Permian volcanic activity. This deep origin makes the site a rare window into the continent's early geological history.
