The "eco-trail" is a misnomer.
Hunter's Road is the track that runs along the border between Bots and
Zim and can be driven by anyone, anytime. It is not owned by anybody.
The road is quite safe, but in the wet season becomes impassable in
places because of the black cotton soil mud.
There are some awesome spots to bushcamp along the road - read the trip
reports on the Overland Forum.
