Praia do Ribeiro do Cavalo

One of the most jaw-dropping anchorages on the Portuguese coast, Praia do Ribeiro do Cavalo sits tucked beneath towering limestone cliffs inside the Arrábida Natural Park — you drop the hook off a tiny, hard-to-reach beach with water ranging from emerald green to Caribbean blue. Getting here by sea is actually the easiest way in, since the land approach is a serious hike. The dramatic cliff scenery and pristine water make it worth every bit of effort.
