My wife and i will be using our Kia Sportage 4x4 with low range and our friends have a Chery Tiigo suv. We will be in the reserve the weekend of the 25th May. I believe we can only do the reserve section with a 4x4. Is this correct. We will come prepared to tow the Chery if necessary. We are spending another week in the Knysna area and feel we will just be more comfortable in our own vehicles. If a 4x4 is really necessary then we will have to just use the Kia. Yours truly, Chelton Hamer.
