Routes through Swazi & Swazi to Tzaneen

[Skotse_Boer]

Doing a trip in 2 weeks from JHB to Swazi, entering Swazi in south east and then up to Piggs Peak.
Anyone know of any alternative routes not on the main tar? Nothing too heavy tho

Then riding from Swazi to Tzaneen and looking for alternative routes as well.

Any suggestions will be great.
