Natal is the capital and largest city of the state Rio Grande do Norte, located in northeastern Brazil. The implementation of the Via Costeira (Coastal Highway), a 10km long avenue along the shore and dunes, was the true starting point for the beginning of tourist activity in the State in the 1980s. The main hotels are concentrated along Via Costeira. Natal has several tourist attractions and is known for its natural environment (such as the waters of Maracajaú and the largest cashew tree in the world), for its historical monuments and buildings (Forte dos Reis Magos, the Alberto Maranhão Theatre and Newton Navarro Bridge), for its beaches (such as Ponta Negra, Pipa, and Genipabu) and also for its off-season carnival, the Carnatal. The city also boasts the second-largest urban park in Brazil, the Natal Dunes State Park.
