The dune road to Gharagab is no problem and can be negotiated by only 2X4. This is a one way only - getting to Gharagab. The one way exit road from Gharagab to Nossob river is somewhat challenging. Just common sense, deflated tires, 4X4 low range in second gear, do not spin the wheels or storm the dune but just keep momentum.
