Bangladesh is a large and densely populated country. However, the casual tourist may find it difficult to navigate this country, where tourism by Westerners is virtually unknown. Perhaps one of Bangladesh's greatest treasures are its people; the country is packed with friendly, honest, and amiable locals who are willing to spend time acquainting themselves with the passing tourist. Crowd of locals surrounding you to inquire about your home country, job, marital status, etc. may at first be disconcerting--but don't worry, the locals have good intentions. The people can be impressionable, so make sure to leave a positive impact.
