Its just opoosit Defence view on main by pass. Dont go towards CBM. Basically the approach is from under the bridge that goes towards korangi industrial area. Or much easier way is just park your car on the jam sadiq by pass, climb up on the "bund' thats on the left ( as you are going from shahrai faisal towards korangi) and down below you will be able to see the rally.
On the map above, it is in the V that is being formed by Korangi by pass and Korangi Industrial area road.
The 4x4s will go thru a practise round on Saturday and the actual race will be on Sunday.
