Poço do Inferno isn't just gorgeous to look at — it sounds amazing too. Find a nice spot to sit, close your eyes and listen to the water falling down.
Poço do Inferno is an interesting place to start out your day in São Pedro. This cascade of water is recommended by fellow travelers, but it isn't the only thing to do here. Save time for other sights like Serra da Estrela Nature Park, Covão d'Ametade, and Ski Parque to fully appreciate what the area has to offer.
