Lying 10km north of Foz do Arelho, SÃO MARTINHO DO PORTO is the main and most appealing resort between Peniche and Nazaré. Low-key and largely low-rise, it’s an easy-going place favoured by families. The reason for São Martinho’s popularity is its beach, a glorious sweep of sand that curls around an almost enclosed bay and shelves gently into the sea, making its waters wonderfully warm and calm. You could easily spend days tramping the boardwalks and dune paths around the bay, hiring a kayak or pedalo or climbing the ochre cliffs above the quayside to the lighthouse. There’s also an older part of São Martinho to explore, up the steep hill behind the more modern bay-side streets – the easiest way up is to take the ascensor, a lift departing from inside the turismo building, which whisks you to an upper square with sweeping town and bay views.
