You want to visit Kuakata on your next trip. Kuakata is called the sea daughter of Bangladesh. Between kuakata and cox's bazar beach I think cox's bazar beach is more beautiful so your family suggested you to go to cox's bazar instead of kuakata beach. But Kuakata should be visited to enjoy the sunset and sunrise view. Apart from this, one of the places to visit here is Lal cakrar Char, Jhowban and Lebur Char. Hope you visit there on your next trip and share your experience with us. good luck
