Create an itinerary including Boca do Inferno
Boca do Inferno, or "The Mouth of Hell," features a natural rock arch with a cave that is known for sucking in ocean waves and shooting water out the top. Nestled in a dramatic environment of eroded cliffs and enormous waves, the site is a well-known photography spot. You can easily reach it by foot, and then follow stairs and bridges around it to get a better view or climb down to the cave if the ocean is calm. Be aware, however, that locals advise against climbing due to the sharp rocks.

  • The 'Hell's Mouth' is a rugged coastline of ravenous seagulls. Possibly too commercialised for our liking, and annoying paths lead you to poor views. Go off-piste. Risk being arrested... or...

  • A nice spot for a bit of photography. The land had made way for the sea coming inward and it looks like an open mouth.

  • This place is quite something ... it's raw, natural beauty is stunning. Combined with the fact that historically many people have lost their lives there for various reasons, makes this place mystic and somewhat eerie. Definitely worth the trip as it is simply beautiful. If you take a walk 500m north from there, you'll find a little cartagena seeking the best hot dogs you've ever had!!!
  • Spectacular view!! I had a chance to visit this wonderful place many times. It was always stunning whether it was cloudy or sunny. Totally recommended if you are fond of hiking
