major fluvial outlet: through the Branco river, reaching the Negro river, heading from there to Manaus and São Gabriel da Cachoeira. Even so, the most important river in Roraima still poses additional difficulties. Tourism Roraima has great tourism potential, especially in ecotourism. Because it is located in the extreme north of Brazil, in the northern part of this country and because it borders on three South American countries, Roraima maintains close commercial relations based on tourism with these countries, especially Venezuela. Natural attractions are the main tourist points of the state, especially Mount Roraima. Mount Roraima is one of the oldest places on the planet and attracts many tourists from all over the world. Archaeologists have a strong interest in Pedra Pintada, which is the most important site of archaeology in the state. In it, there are inscriptions of ancient civilizations, such as rock paintings, pieces of ceramics, hatchets, necklace beads, among other artifacts that indicate the history of human evolution, dating back to four thousand years. The rock is a granite monolith sixty metres in diameter and about 40 metres high. On the outer face, there are red rock paintings that are still considered an enigma for scientists. There are also funerary caves up to 12 meters long. Pedra Pintada is located in Pacaraima. Serra do Tepequém is also a state tourist attraction. It has a rich handicraft in soapstone and its area is free to explore diamonds. The place serves as a trekking practice, to the Paiva, Sobral, Barata and Funil waterfalls. The plateau is the culmination of the entire mountain, where the mountain range that delimits the borders between Brazil and Venezuela begins. It has an average altitude of 1,500 metres and is located in the municipality of Amajari. Another tourist spot in the state is Mount Caburaí. Geographers have proven that it is located 70 km north of Oiapoque, Amapá, which makes the mountain the northernmost point in Brazil, having been recognized by the official institutions responsible for geographic territorial demarcations, such as the Ministry of Education and the Brazilian Institute of Geography and Statistics (IBGE). Also noteworthy is Lake Caracaranã, in the municipality of Normandia. With almost 6 kilometres of perimeter, it is known for its fine sand beaches surrounded by cashew trees.
