The water is clearer than in Turkey, but the sea itself is shallow, 200 meters wide and 1.5 meters deep. For children, of course, it's super. Of the cons, it is often windy and there are strong waves.
The beach was advised at a hotel in Baku. The beach is wild.The beach and the sea are clean enough. There is some mud on the seashore. There were algae in the sea, but you can find a completely sandy approach.
There were not so many people for the weekend.
