Tourism is also very important with the huge São Simão lake nearby. The reservoir (674 km2 and 12,5 billion cubic meters of volume) is used for fishing, swimming, and nautical sports. One of the greatest tourist points of the region is the artificial beach on the banks of this reservoir, twice the size of Guanabara Bay, and formed by the building of the São Simão Dam. See video at São Simão. This beach is called Praia do Lago Azul and has one kilometer of beach with bars, showers, bike path, track, bathrooms, a camping area, and tropical vegetation.
