Brazil is a very large, incredibly diverse and vibrant country. It’s just about as large as the United States, excluding Alaska and Hawaii, and has a population of more than 200 million. You can find all types of landscapes in Brazil, and the population has history in indigenous people as well as immigrants from Africa, Europe, and Asia, resulting in a very very diverse and cosmopolitan culture. In my experience, Brazilian people are friendly, open, helpful, well educated, well traveled, and interested in meeting and interacting with visitors to their country.
