Old Richmond Rd to Jacks Creek Pike, the sanctuary is on the left before the municipal line ends.
To get to this spot you have to walk the stream bed to the right of Evans Mill. Hopefully the water is low enough to do so but not low enough to spoil the shot. You MUST be careful when doing this, it is not for those unsteady on their feet. Just know when to stop before it gets too dangerous.
Off the marked path at Raven Run Nature Sanctuary, a pool of water divides the limestone cliff from the forest across.
