Swallow Waterfall is only 9 meter high, not much water, but has such a magic beauty, maybe for being inside nice woods in grooves on moutains close to colonial style City of Goias, former province capital called Vila Boa de Goias. This fall really hides hundreds of swallows during right times of the year, in holes in its arenite or soapstone rock formations, drawn by water for million of years. To get there, being in City of Goiás, you should drive to the city exit alongside the Santa Barbara church (the highest up on the hill). Afeter 6 kilometers of non paved road there´s a crossing point - take to the right to the waterfall. There may be some sign - Cachoeira Andorinha, which is inside a property called Fazenda (farm) Manduzanzan (African name). It´s 500 meter more till the entrance, where they ask you the payment of a visitation fee (R$ 2 in 2002).The trail goes for another half kilometer inside a nice wood, giving you an idea of the mountains around, where the crystaline water pours down from. In some of them, almost three centuries ago, gold also used to come down the hills.
