Portinho da Arrábida
Swimming and diving
This delightful small beach nestled in a bay has calm, crystal blue-green water that
is excellent for swimming and diving.
Neighboring Coelhos beach has golden sand and very calm waters.
They're perhaps the two most beautiful and tranquil beaches around Lisbon,
although difficult to reach (only by car through narrow roads).
Nearby is Praia das Picisnas, a
peaceful beach sheltered by pine forests and ideal for long walks by the
sea.
Public transport is virtually non-existent, so you'll need your own car
to reach it.
