Depending upon which map you are looking at, this geocache will either appear to be hidden in the middle of nowhere or it will appear to be hidden right beside the Seven Creeks Way. At any rate, no bush bashing is required, and there are clear trails that will lead you to GZ. As a pointer, the relevant Topographical Map does not have the trail marked, but it is marked on Open Street Maps.
Seven Creeks Way is a walking track that links between West Cliff Colliery and the 10B Management Trail, for the most part in Dharawal National Park. The turn off on 10B is directly opposite the 10R intersection. You can approach from either of the listed parking waypoints, or you can do a car shuffle and walk the track in its entirety (highly recommended). As the name suggests, the track crosses seven creeks along the way. With a little creativity, each creek can be swum in, albeit that some have bigger swimming holes than others. My Scouts managed to swim in them all over the weekend that the geocache was hidden.
I was in the area with my Scouts and just happened to notice that this part of the walk along Stokes Creek is not in Dharawal National Park. Thankfully I had a small geocache in my pack (just in case!), and so was able to leave something behind. The next time I am here I will swap the hide for something more substantial. One of the other Scout Leaders with me reports that this area is a Crown Reserve once designated for a Rifle Range, hence the shape of the land excluded from the National Park.
The area around ground zero has several swimming holes, some wind caves, and a waterfall that you can climb up and behind to emerge out again. My Scouts spent over three hours here exploring and having fun. I’d certainly encourage you to have a swim! Please be aware that Dharawal National Park is rich in both biodiversity and Aboriginal sites, as such I urge you not to walk off track to reach GZ.
