Algar Seco is the defining natural attraction of the Carvoeiro coast: a dramatic headland of golden limestone sculpted by the Atlantic into arches, sea stacks, and deep fissures. A wooden boardwalk leads from near the car park along the cliff edge, above sea caves and natural rock pools, with views back over the town's sandy cove.
It is a short walk from the centre of Carvoeiro — 15 minutes on foot along the cliff path. Go at low tide to see the full drama of the rock formations and to scramble down to the pools. A cafe at the headland operates in season. The light at sunset, when the orange limestone turns gold, is particularly good.
