Egg Rock, also known as Kurraragin in the Yugambeh language, is a prominent geological feature situated in the Numinbah Valley on the western side of the Nerang River in Woonoongoora, Lamington National Park. The rock formation, a plug of rhyolite that filled a subsidiary vent on the side of the Tweed Volcano, has become a 410-meter high pinnacle due to the erosion of the surrounding soil and rocks over millennia.

The eruption of the massive shield volcano at Mt Warning sent lava flows across the surrounding land, and in some places, lava forced its way up through vents and formed volcanic plugs. Kurraragin is an example of a rhyolite plug from the edge of the massive volcano.

Early visitors to Kurraragin enjoyed climbing to the summit and taking in the breathtaking 360-degree views from the top. In fact, the rock was even featured on the illustrated front cover of The Queenslander on May 4, 1938. However, climbing Kurraragin is now unauthorised.

The rock formation was declared an Aboriginal Heritage site of importance and is now closed to the public. The Yugambeh people, the traditional custodians of the land, hold a strong connection to the area and the rock. It is a sacred site that plays an important role in their culture and history.

While Kurraragin (Egg Rock) may no longer be accessible to the public, its significance as an important cultural and geological site cannot be overstated. It serves as a reminder of the rich history and natural beauty of the region and the importance of respecting and preserving it for future generations to appreciate.

Binna Burra Lodge provides the best viewing vantage point of this amazing rock formation. Visitors to the area can still take in the beauty of Kurraragin from the walking tracks at Binna Burra, where they can enjoy stunning views of the surrounding rainforest and the rock itself. The best accommodation at Binna Burra Lodge to take in views of Kurraragin are their brand new Tiny Wild Houses and the luxurious Sky Lodge apartments.
