Maravanthe Beach is a unique beach with Kolluru river on one side and sea shore on the otherside. Now the well developed NH66 runs between beach and river. Earlier one can view both and a narrow stretch separated the river and Arabian sea.
There are street vendors nor there are other facilities. One can just enjoy the view point of river and Arabian sea and move on.
If you are driving on NH66 and crossing Maravanthe, do stop for the view.
