Praia de São Pedro do Estoril

It's got a Blue Flag and a low tide affords a large expanse of golden sand. Otherwise S. Pedro's narrow beachfront is usually the domain of surfers and anglers, except during high summer when local residents make it their own, helped by excellent road and pedestrian access (although the railway station is a bit of a jaunt). When the tide is out it exposes a promontory known as Pedra do Sal (Salt Stone), a geographical feature made up of limestone and marl and believed to be between 90 and 120 million years old. Leisure facilities extend to a decent restaurant and one or two smaller cafes. A car park collects a lot of traffic, inevitably at weekends and most days during August.
