This is a better image of the beaches at Foz do Arelho and Bom Sucesso at the opening of the Lagoa do Obidos seen from the Bom Sucesso (south) side. Click on the image to enlarge.

Situated at the mouth of the north side of the lagoon Foz do Arelho has been a much-loved destination for the jaded Lisbon city-dweller. Leading inland from the enormous wave-pounded beach is the tranquil Obidos lagoon which in days gone by stretched as far as the fortified town. Now it is the place of work of many ‘clammers’ who extract the delicious local clams which can be found in the restaurants within the town.
