go to vulcan and keep heading north, stay on that road for a while, don't turn off it, keep going (it will twist around) until you see the sign for the arrowwood turnoff, take that and keep going till you hit arrowwood. I'm not sure how many km's it is from vulcan, but I think is around the 30 minutes drive time mark
once you are in arrowwood, its not too hard to find, due to the fact that there really isn't that much there, I'm not 100% sure where it actually is, but I think if you take the 2nd turnoff into arrowwood, its just down that street.
hopefully these instructions work, and if no one else can give better instructions, hopefully these work
