The Boca do inferno (hell’s mouth) is an amazing blowhole where you will probably want to return for a second and third visit. Every new visit will provide a different experience as each tide or condition of the sea will make the blow and sounds associated differ and special. The name is mysterious and I wonder if it may have been influenced by the basalt-octagons reminding huge teeth; or the mouth shaped lava tube; or the sounds heard.
There is a legend associated with this place, a good description can be found in:
