Welcome to Overland Bound. The area is amazing, such a beautiful place on earth. There are several tracks which are quite easy to find. The more southerly way is more challenging (parts of a leg of the Dakar in the old times) but absolutely amazing. Good to go with a D2 and driving experience. If it is too much there is a possibility to reach tarmac about in the middle of the distance between both cities. Be aware: depending on the weather, the dry saltlake can be a risky place to navigate.
