I have never been there in the morning but most probably no such activities in morning; it is not popular in morning among locals especially during this hot weather.

Nor on public beach. I believe one of the resorts has it

There is no entrance fee for the open beaches except few resort along the shore line, which are paid. Just you have to take care if you are going there alone without family, as only one beach is for bachelors.

i don`t think so

It’s Baher Villas Beach Resort... Yes, couples with children can swim and enjoy the beach and the swimming pool of the resort.

yes it is open for every body

I have witnessed full clothed females swimming in Half moon bay It depends how far you travel down the coast to how private it gets the further south you go the better there is a water park on one of the compounds that you can pay to go on iIts on the left after the water desalination plant just befor the road start to drift right that's on the coast road out of AlKhobar

as i know i spent full day and up to 9-10 pm night , exactly i cant say whether it is open full night or not
