Municipal boundaries: The climate is moist tropical with an average temperature of 27 °C, with two well defined seasons: dry and rainy, with regular rainfall in the period of October to March.

This type of climate favors the formation of vegetation made up of savanna, broken by farmland and pastureland.

The town is located on the Araguaia River and attracts thousands of tourists, especially in the dry season, from May to August, when extensive sandbanks are formed providing beaches for sunbathers and swimmers.

The main economic activities were agriculture (including lumber extraction and processing), commerce, hotels and restaurants, and public administration.

In 1939 the name was changed to Aruanã, a native fish and the dance of the local Indians, and the village became a district in the municipality of Goiás.
