A pretty cove a short walk north of the centre, framed by cliffs and the chapel of São Sebastião above.
Reached by a zigzag path down the cliff, São Sebastião feels a touch wilder than the central beaches while staying within walking distance of town. The chapel above gives it its name and a fine viewpoint.
It is a pretty cove framed by rock, north of the centre, with the little chapel of São Sebastião standing on the cliff above. The walk down sets the tone, quieter and more natural than the busy central bays, with the sound of the sea closing in as you descend.
The sand is golden and the cove has a more sheltered feel between its rocky arms, though the open Atlantic still reaches in. Summer gives the calmest, warmest water for swimming, while in spring and autumn it is cooler and often almost empty. Watch the tide, as the beach shrinks and the rocks appear as the water rises.
Lifeguard cover is lighter here than on the main beaches and mostly limited to the peak summer weeks, so read the flags when they fly, green for safe, yellow for wading, red for no swimming, and take extra care outside the season when no one is watching. The rocks and the reef at the northern end call for a cautious eye.
Facilities are minimal, which is part of the appeal, so bring water and anything you need for the day. It suits confident swimmers wanting a quieter dip, walkers linking the coastal paths, and anyone who likes to watch experienced surfers work the reef at the northern end.
Because it takes a little effort to reach, it stays calmer than Praia do Sul even in August, a good escape when the central sand is packed. Come at mid to low tide for the most room, mind the rocks that dry out, and pause at the chapel viewpoint on the way back up for one of the best angles over the coast.
