Hell's Mouth

  Hell's Mouth sits at the edge of the Atlantic Ocean in the picturesque district of Cascais, just a short drive from Lisbon. Known locally as "Boca do Inferno," this natural chasm was formed by the relentless erosion of cliffs, creating dramatic waves that crash spectacularly against the rocks. A fascinating aspect of Hell's Mouth is its legend, which dates back to the 19th century, claiming it was once the dwelling place of a dragon that terrorized the area. Visitors can explore the surrounding cliffs and stunning coastal views, particularly captivating during the vibrant sunsets of September. This unique spot also offers glimpses of seabirds, making it a popular lookout for nature enthusiasts.
