Algar Seco is what the Atlantic does with limestone and ten thousand years: a sunken amphitheatre of golden rock at the boardwalk's end, carved into chambers, arches, potholes and blowholes that breathe with the swell.
Stairs descend from the clifftop into the formation, where paths wander between pools and pinnacles. The celebrated corner is 'A Boneca' — the Doll — a small cave whose double window frames the sea in two stone eyes; a seasonal café-bar sits improbably inside the rocks beside it, serving sunset drinks in the formation itself. In calm summer water, swimmers and snorkellers work the rock pools below; in winter swell, the blowholes thunder and spray.
Free, unfenced and genuinely sublime — keep children close and footwear sensible.

History & context
The name joins Arabic and Portuguese — algar, a cave or sinkhole, and seco, dry — for a formation the sea carved and then half-abandoned; fishermen kept boats in its shelter long before the café and the photographers arrived.
🗓️ Best time to visit
Late afternoon into sunset; big-swell winter days for the blowholes (from a respectful distance).

Frequently asked questions
What is A Boneca?
A small cave whose twin openings frame the ocean like a pair of eyes — Carvoeiro's most famous photograph, named 'the Doll'.
Is it safe for children?
With hands held, yes — paths are uneven and unfenced above the water; the viewing areas near the café are the easiest ground.
