Marina beach is the beach that if u visit this place then u will feel what really the nature is.it is the place where you will feel that your in the most beautiful place in the earth.Walking in the sea shore and in the sands n bathing in the water it was amazing friends.For me I don’t have any drawbacks for this beach because I have only visited once in this place and I like it.But what are the real demerits are that I don’t know and I don’t care also for me the sight was nice n beautiful.
