During the 1980s gold rush, Alta Floresta became a mining ground and quickly grew to over 100.000 inhabitants. As the economic profit of gold mining declined, so did the number of people living here. The current population is estimated under 50.000 (2010). Today, Alta Floresta is diverging economic activities, and ecotourism is one of the focal points for development.
Alta Floresta has a rather large airport of its own. From Aeroporto de Alta Floresta, several airlines operate daily flights to many Brazilian cities.
- Airport Avenue Lake (Lago da Avenida do Aeroporto). A good place to see capivara grazing and egrets nesting.
