Mirang Pool campground is located at the northern end of Heathcote National Park. It's a basic but pretty campsite with no vehicle access and no facilities so you'll need to carry everything in and out with you, including drinking water.
The hike there from Heathcote train station takes 45 minutes, but if you park at the end of Oliver Street it's a two-kilometre walk easily done in 30 minutes.
To get there from Heathcote train station take Oliver Street to the very end which is 900 metres and takes about 15 minutes. At the end of Oliver Street take Goburra track which is steep in parts and requires some rock scrambling. Upon reaching the Pipeline trail turn left and keep walking until you see the blue signpost for Mirang Pool at the top of the stairs.
Enjoy a well-deserved paddle in Mirang Pool to cool off after your hike and then set up camp for the night in the soft, sandy patches between the trees, gymea lillies and rock platforms.
