Praia de São João do Estoril
Praia da Poça, also known as São João do Estoril, is a popular little beach at the start of the Estoril - Cascais coast. As with all the beaches along this stretch there is the wide promenade running behind, with a couple of places to eat.
Access at Praia da Poça is good. Just a short distance from the N6 "Marginal" road and about halfway between São João and Estoril train stations, getting here is easy too.
The beach here is sandy, although apart from the middle of the beach the shoreline is fairly rocky. Whilst this means the paddling might not be perfect it also means there are plenty of rock pools to explore when the tide is out.
Overlooking the beach on the eastern headland is the old Forte de São Teodósio da Cadaveira, one of the 17th century fortresses built to guard the entrance to the River Tejo.
