One of the top destinations to visit in Bangladesh is Cox's Bazar Beach. Known as the longest natural sand beach in the world, Cox's Bazar beach is 150 kilometers long, at high tide 200 meters, and low tide 400 meters wide. This is an absolute must-see for all beach lovers out there! Just be careful, quicksand is a relatively common feature of this beach during low tide. And one more notice: Bangladesh is a conservative Muslim country, so both men and women should consider modest clothing even while swimming.
