The Moonee Beach Trail

The undisturbed Munmorah State Conservation Area is located between Budgewoi and Catherine Hill Bay in Lake Macquarie on the stunning Central Coast. Along this underrated stretch of coastline is the Moonee Beach Trail, a fantastic coastal walk, which leads you to the most incredible pink coloured rocks inside a sea cave! 



A management trail, about 2km in length, runs adjacent to the ocean and initially guides you past Timbers and Ghosties Beaches, before spitting you out onto Moonee Beach. A lovely serene spot in its own right which acts as the gateway to the world-class pink rocks found on the traditional land of the Awabakal people.



At the northern end of the beach, you’ll trade sand for rock platform as you head towards the main sea cave. Almost immediately, you’ll be met by scintillating rock pools, edged with that other-worldly, pink-tinted rock.

If you’ve fought off the temptation to go for a dip, continue north following the coastline. You’ll then arrive at an obvious sharp bend to your left which takes you to the sea cave and the main attraction – unbelievable pink rocks!

The Sea Cave

As you approach the cave, you’ll find a large divide in the rock platform, creating a narrow passage for the oncoming waves to flow through. Each crashing wave violently fills the gap, spraying sea water throughout the cave. In between waves, the water levels drop, revealing immaculate pink coloured rocks on either side of the split rock platform. Prepare to be genuinely awestruck by the vividness of the colour.

Given the ferociousness of the ocean, make sure you only explore here during low tide, avoiding any periods of large swell. Check BOM tide predictions for the latest updates to ensure your safety when visiting.

It’s possible to see more of these pink rocks and other sea caves further northwards on this stretch of coast. But accessing them is particularly difficult and dangerous. This sea cave is the safest to access. 


The Science Behind The Pink Rocks

Such is the case when there are any amazingly coloured coastal landforms or phenomena, we have algae to thank. Well, to be more specific, macroalgae called Crustose coralline! When deposited from a group of red seaweed, the algae form thick calcified crusts on the surface of the rocks, giving them their amazing pink colour.

Just as impressive is the fact that marine algae like this, produce around 50-75% of the earth’s oxygen and absorb around 25% of its carbon dioxide. So not only do the pink rocks make for an epic photo, but they’re literally contributing to and helping to preserve your life on earth!
