I have started devising a slightly better alternative to the road.
The plan is to use the basic route google suggested for a Hanmer to Picton journey (SH 7 >SH 65 >SH 6 >SH 63 etc), but then to branch off that at every dirt road opportunity I get.
I have been logging it in Excel form so far (see attached).
It hasn’t been completed yet, because based on time available from Point 14 we’ll either head along the Google Maps prescribed route, or if we’re doing good on time, we may head up SH 6 towards Richmond and pick up a bunch more dirt tracks along the way.
Still trying to piece together the GPX file though.
