Track from Wellington Falls

Today we got to Wellington Falls and saw on the map a track that crosses the Falls and then wonders up to the Thark Ridge.
The question is this:
We tried to find the 'entrance' of this track at the end of the 'Springs to Wellington Falls' track but to no avail.
Anyone please have a clue where it starts ? (I know we will have to cross over falls )
Thanks
