I was there with my wife last May, it wasn't very crowd, the beach has a fees to enter as you have to rent an umbrella and chairs ( one umbrella and 4 chairs were about 80 EGP) !!!
as everything they are getting higher every year.
The beach was clean with golden sand.
My friend Kareem brought me here on my last day for watching sunset. It was really a wonderful place to view sunset (later we went to Montaza Gardens where sunset is even more exciting). We had some tea and enjoyed the kids playing around and the nature.
Mamoura beach and boardwalk is very pleasant to visit. The beaches are well kept and the water is beautiful! Most beaches are private for a fee. Or one could walk to boardwalk for free. There is a charge to get into Mamoura subdivision though.It is a very low fee.
