day trip to Edge of the world (Riyadh)

I am planning to visit this interesting spot on one of the next weekends. I have a local 4W driver and look for a guide to join this trip for a proper route; other interested people are highly welcomed (shared costs ?).
Major targets are walking to interesting spot for taking excellent pictures and having a nice rest to "inhale" the special atmosphere.
Happy for any help or comment!
