The vibe
Honeymoon beaches
Gorgeous enough to justify the flights, quiet enough that nobody photobombs the proposal shot.

Portugal · The Algarve
Praia da Marinha
Book the flight now.
The one on every "best beaches in Europe" list that somehow still isn't ruined. Gold cliffs, water the color of a lie, and a staircase from hell that filters out everyone who skipped leg day — which is the point. This is the beach that makes you understand why the Portuguese built cathedrals: they looked at this and thought, "we should try to compete." They were wrong to try.
Best: May–Jun or Sept →

Portugal · The Algarve
Praia do Camilo
Worth a detour.
A postcard beach you access via a wooden staircase clinging to a cliff face like a barnacle. Small, golden, sandwiched between striated ochre rocks, with water so clear you'll feel watched. The restaurant at the top is genuinely good and genuinely expensive — the kind of place where the grilled fish costs what your hotel did, and you pay it because the view has colonized your brain.
Best: May–Jun, Sept →

Portugal · The Algarve
Ponta da Piedade
Worth a detour.
Not one beach — a labyrinth of sea caves, grottoes, and rock formations at the tip of the Lagos headland. You swim between cathedral-scale arches while small boats full of sunburned tourists motor past taking your photo. The water is absurd. Bring goggles. The place is a geology lesson that happens to be a swimming pool.
Best: May–Oct for swimming →

Portugal · The Algarve
Praia do Castelo
If you're already there.
A small, cliff-wrapped beach at the quiet end of Albufeira's western sprawl, named for a rock formation that looks like a castle (if you're feeling generous). Good sand, clear water, a wooden boardwalk that keeps the dunes intact, and a beach bar that's genuinely decent. The kind of beach that won't make a top-10 list but will make the day you're there better than the day you weren't.
Best: May–Oct →
