Umm Bab Road Bonus Cache
The cache is not at the above location. To find this bonus cache, you will have collected the info from the other 4 caches.
Not suitable for saloon cars, but an SUV with good clearance is probably OK. Although not far off a busy highway, there is a lot of soft sand about, so do not travel alone, and take food and plenty of water.
Some rock scrambling required for all the caches, depending on how close you can drive.
