Algar Seco

Algar Seco is a limestone cliff formation in Carvoeiro carved by Atlantic waves into caves, rock passages, and natural pools at varying water levels. A wooden boardwalk about 570 meters long guides visitors through observation points and down to these formations below.

Marine fossils found in the limestone date back about 24 million years, showing that this area once lay beneath the ocean. This geological past shaped the rock formations visible at the site today.

Local fishermen have used these cliffs as navigation landmarks for generations, developing specific routes based on the rock formations they encounter. This practical connection between people and the landscape continues to shape how the community relates to this place today.

Steps and pathways lead down to the caves and rock formations, though surfaces can be wet and slippery from ocean spray. It is best to visit on calmer days when water levels make the formations easier to explore safely.

A cave formation called A Boneca features two circular openings that frame the ocean like natural windows to the Atlantic. This distinctive rock formation has become a favorite spot for visitors seeking this particular view.
