Agree with Stijn on this one.
Just maintain your heading up the right valleys towards Mweni. The paths split numerous times so maintain a bearing to general direction.
If you are unable to gain the pass on the first day the valley below mweni is pleasant, and well watered for camping.
Evidence of isolated deliberately)dagga fields are everywhere.
No water up Mweni, but on topping out there is a well running river.
Rockeries is easier to descend than Mweni would be.
Neither are technically difficult. There is an interesting rocky descent into the river at the base of Rockeries.
Please be aware of the fact that Rockeries is a major dagga route, as is the path out into the inhabited areas. It is about 2m wide in some places due to the donkey trains, so you won't miss it.
It is far easier to find your way outon the rockeries route than it would be to find your way in.
The locals are pleasant, and so is the tourist centre.
The kids will freely tell you that dagga grows in the patches.
An awesome area. If you haven't before, then you need to visit the Mighty Mponjwane. An awesome block of rock indeed!
