    We did this place on the 6th March 2016 and figured I’d add what we found here:

    The place is called Marramarra National Park and the walk we did was from the carpark down to the Marramarra Creek Campground. This walk was around the four kilometre mark each way and has one fairly steep section dropping to the bottom of the valley. I noticed this on the way back up by the HT power lines that you see way up as you start the climb yet only a short time later you’re at the base of one of the stanchions. Other than this there are some considerable undulations along the way to soften you’re up.

    Marramarra Creek is slightly brackish as it is tidal but apart from this it makes for great swimming in the numerous deep sections.

    The place, due I suspect to the long and steep track, is vary rarely used so you’ll be almost guaranteed of having it to yourself.

    Getting there from the entrance is fairly easy with the only trick being to not stop at the first carpark you see continue in the almost five kilometres to the gate at the top of the track.

    The track surface requires footwear however the track’s lack of people requires little else. We had a sarongs ‘just in case’.

    The campsite has fire pits, toilet and a visitors book and gravity to stop your tents from floating away. So bring your water food and anything else you need.
