‪Gateway to the stunning beaches of Rio Grande do Norte, the city of Natal is perched on Brazil's Atlantic coast, at the mouth of the Potengi River. Escape the bustle at secluded Pipa and Pirangi beaches or live it up at Genipabu and Tibau do Sul. The city is surrounded by Dune State Park. Go on a buggy ride over 30-foot sand dunes or tour the dunes on a dromedary tour. The city is home to the cleanest air on the continent, according to NASA, and also to the world's largest cashew tree.‬
