While not a hard place to get to, you def need to be 100% prepared to come out here as it is a remote camp. Normally we come out here in the winter-spring months, and you will generally see other traffic, but you need to be well prepared with food, water, fuel, camping gear and a reliable 4wd. It is regarded as the most remote campground in NSW.

I love Fort Grey.
