A waterfall that falls right on the roadway and you can drive under it by car or stop and go out to swim in it :) The best time is to go after the rain, when the it is full of water. The tunnel that leads to the waterfall is not recommended to enter cause of rockfalls. So I advise to ask locals at Ponta do Sol of the conditions from last days before entering it. Or better not to risk and park in Ponta do Sol and walk untill here (around 15 minutes).

Best time to come right after rain for waterfall to have full water, but not wait to long, since after some time after heavy rains the water becomes brownish.
