The Algar Seco are a series of fascinating cliff formations that have been carved out of the limestone bedrock landscape with geological formations of the Miocene, with marine fossils visible everywhere.
The turquoise blue and green of the sea contrast with the terracotta and yellow tones of the wonderful cliffs and algares.
The Carvoeiro boardwalk is a picturesque cliff top walk that leads from the Nossa Senhora da Encarnação fort to the Algar Seco rock formation. This short walk is along an elevated wooden walkway, which skirts the top of the cliffs and offers wonderful views over the stunning coastline.
The Forte de Nossa Senhora de Encarnação is a minor fortification that once guarded the Carvoeiro coastline. The fort originates from 1670, but only a small section of the wall remains, as most of the fort was destroyed by the 1755 earthquake. The present whitewashed building is the reconstructed fort (1825), which has been since converted into a nursery.
