Most of the areas of Bangladesh lies within the broad delta formed by the Ganges and Brahmaputra rivers. Lands are exceedingly flat, low-lying, and subject to annual flooding. Much fertile, alluvial soil is deposited by the floodwaters. The only significant area of hilly terrain, constituting less than one-tenth of the nation's territory, is the Chittagong Hill Tracts in the narrow southeastern panhandle of the country.
Rivers are the most important geographical features in Bangladesh, and it is the rivers that created the vast alluvial delta.
Bangladesh is a diverse country, ranging from the low lands of the Ganges Delta to the heights of the Chittagong Hill Tracts.The country boasts a number of delightful destinations including cities, national parks, beaches, and rural villages.
