About
Quick facts: Raging Atlantic waves crash against the rugged cliffs, creating spectacular water explosions visible from the viewing platform. The site earned its name after sailors witnessed the ominous roar and swirling whirlpools resembling hell's mouth.
Highlights: The jagged cliffs form a dramatic natural arch where waves thunder through narrow caverns, producing a deafening roar and misty spray. At sunset, the sea glows with fiery hues reflected on the rocky walls, offering a breathtaking spectacle few expect.
Insider tips
- Wear sturdy shoes for walking on uneven, sometimes slippery rocks.
- Bring a windbreaker as the sea spray can be chilling, even on warm days.
- Best photo spots are along the upper cliff edges just before sunset.
- Avoid weekends if you prefer a quieter experience; weekdays are much less crowded.
