I dont have a good opinion about the marina beach. Because in my concern Marina beach is an area where the wastes are dumped. The water in it will be saline for ofcourse reasons. But eventhough it is saline we cant dip our legs into it due its purity. The water became too dirty due to the wastes dumped in that. For I will say that Marina is not much safe too. Marina is the largest beach in its length. So that much area is covered by wastes. For sightseeing and for relaxing marina beach is a good option for everyone. There are easy ways to reach Marina beach. There will be no issues in accessing Marina beach. For peoples who are coming from outside will get accommodation in nearby hotels. As I dont have a good opinion about Marina beach. It is not a good beach in its ambience. There are other beaches in Chennai which gives good experience than Marina.
