Potential Camping Spots:
OPTION 1. If you prefer to sleep in the car, and want to be nearby the ADNOC LIWA:

OPTION 2. If you want to set up your tent nearby the starting point:

Follow the directions for the starting point to pass through the gate, then go a little bit right onto the sabkha.
OPTION 3. Camp deeper inside LIWA dunes for a tranquil night:

Enter at this point and follow the dirt track that leads inside the dunes. It's a hard track with little bit of sand, where deflation is not needed. Guaranteed of a quiet night under the stars. GPX file in attachment.

Myself, i will probably go for option 2 and camp nearby the starting point and sleep in the car.
Feel free to let us know what your plan is. The third option is probably the most private one and there is plenty of space in that area to find something that gives you privacy.
