It is hot enough now to swim. The water is a little cool, but it is ok once you get in. The thing I love most about this area is you can let your dog run free without anyone or anything around. I had to stop doing that in Zor because too many people were around.
To get to 285, it is about an hour drive from the city. Pass the Wafra and Khiran Resort exits and the next exit to your left will be 285. You can pull up to any of the man-made berms (dunes) and walk over to reach the beach.
Bring food and drinks with you because there is absolutely nothing around for miles. The closest store (I think) is at the 40/Wafra Road intersection.
