Yes but Dukhan Watersports club to use it's name is not open to the public so not much point in recommending it to the whole world. They are very stict about who they let in, we even have to apply for our relatives to get permission when we have them to stay.
Sorry, I disagree about Zikreet. It is a beach, it has sand and the sea and is a great place to swim. No, it is not a beach club resort but this question asked about the beach, not a watersports club that is closed to the public.
