Tucked away just two kilometers from Blowhole in a straight line or five kilometers along the road lies the magnificent Bombo Headland Quarry Geological Site. This stunning location, known as Cape Bombo, houses the Bombo Headland Quarry, attracting not only local Australians but also professional landscape photographers from around the world.

Bombo is often overlooked by tourists from Southeast Asia, making it a tranquil haven for those seeking solitude amidst nature’s beauty. On weekends, when other popular destinations are overcrowded, Bombo Headland Quarry offers a serene escape, with only a handful of people scattered at a safe distance of 200 meters from each other.

The formation of Bombo Headland Quarry is a testament to the joint efforts of nature and human intervention. Over thousands of years, the ocean eroded and destroyed basalt rocks, while humans undertook the task of crushing and utilizing these rocks for construction purposes. The unique presence of sandstone within the basalt led to the creation of remarkable 5-6 meter pillars, resembling the landscapes depicted in Martian science fiction.

During the mining of basalt, engineers carefully planned the development to preserve six natural dams, which now stand as geometrically regular stone pillars, serving as a picturesque testament to the quarry’s history. The ocean’s ceaseless work over millennia combined with human activities spanning 60 years, from the 1880s to 1940, resulted in the construction of railways in the area, primarily using basalt as a building material. Eventually, transporting basalt from the region became economically unviable.

Ownership of the Bombo Headland Quarry Geological Site passed to the Metropolitan Water Supply, Sewerage, and Drainage Authority, which, in 1970, built a wastewater treatment and treatment plant at the quarry’s bottom. Despite facing opposition, this decision has preserved the quarry and Cape Bombo. Today, they are included in the state register of heritage, protecting them from any destructive activities. Unfortunately, there is no trace left of the quarry’s mining operations, as the old tram, pier, and crushers have vanished.

However, the wastewater treatment plant remains, cleverly concealed at the base of the quarry, not spoiling the surrounding landscapes. Though the plant may occasionally affect the air quality, during my visit, fortunate wind patterns ensured a scent-free experience. I enthusiastically shared with my friends the remarkable scientific and technical advancements achieved in wastewater purification technology. The plant eliminates all sorts of waste, leaving no unpleasant odor. Nevertheless, there were instances when the wind shifted, leading to a less pleasant experience, but such occasions were infrequent, occurring only once in every four or five visits.

Despite the occasional air quality concern, I wholeheartedly recommend visiting the Bombo Headland Quarry Geological Site to everyone who finds themselves in this part of the world. Even if you decide not to descend into the quarry, where occasional smells might linger, the cliffs of Cape Bombo offer astounding views and always provide fresh sea air.

Bombo Headland Quarry boasts picnic areas, scenic hiking trails, breathtaking vistas, diverse bird species, and exotic vegetation. Avoid the mistake of sticking solely to the pillars; the most captivating views await along the ridge of the hill on the northern part of the cape. Surprisingly, I noticed cars in the parking lot, but very few people exploring the most fascinating spots. Instead, most individuals wandered along the base of the quarry, adjacent to the plant’s walls.

There are two free parking lots on the cape, connected by a path that runs alongside the railway. From one parking lot, you can venture toward the quarry, while the other leads to the ridge, offering panoramic views of both the Bombo cliffs and the expansive ocean. With a couple of hours, you can circumnavigate the entire cape and capture breathtaking photos. Dedicate an additional hour for a picnic in one of the enchanting spots, and you will undoubtedly find happiness in this natural wonderland.

In conclusion, Bombo Headland Quarry Geological Site stands as an awe-inspiring testament to the harmonious blend of nature and human intervention. Its secluded charm, magnificent landscapes, and unique geological formations make it an ideal destination for nature enthusiasts and photographers alike. Plan your visit to this hidden gem and embark on an unforgettable journey through the wonders of Bombo.
