After some driving on dirt roads I found one, but it was full off tourists, about 20 4WD, so I kept going and found my own private pool, I took a video, which I will post later ( as Typepad is blocked in Duabi) I went for a swim, and it was so nice, this is not stagnant water by the way, it is actually a creek ( well they call it a river) it was one of the most refreshing swims I've had in a long time, and the water just appears from out of the rocks

little car I rented, again so nice to be in this water, air temp is well above 40°c
