This water spring is located 2km from the Farm & Hotel, Areia Que Canta. Upon arrival (if you don't stay at this hotel) you park the car and then walk or go by car provided at the farm. The spring is situated in the middle of a lake with crystal clear water. There is very special sand, when you take some sand into your hands and rub it, the sand starts to "sing" during the friction/movement. When you enter the water, some "mystic" things happens as well, it is like quicksand, but it is not - just the feeling of suction power, that you are going down. Difficult to explain - must be experienced to be understandable.
