Praia do Almargem, also known as Praia do Cavalo Preto, is a long, quiet beach just east of Quarteira, part of the same 17km run of sand that stretches all the way to Faro. Portuguese families and couples know it well; foreign visitors mostly don’t, which is exactly why it stays calm even in August.
Behind the beach, the Ribeira do Almargem forms a lagoon that pulls in waterbirds year-round, backed by dunes and a pine forest instead of apartment blocks. You can walk here from Quarteira’s town beach in 15 to 20 minutes, or drive the unpaved 3km access road if you’d rather save your legs for the sand.
Yes if you’re staying in Quarteira, Vale do Lobo, or Quinta do Lago and want a beach day with room to spread out. Skip it if you need facilities right at the car, sun loungers ready to go, or you’re not driving – there’s no public transport out here.
There are two parking areas, one at each end, and a simple beach restaurant if you don’t want to pack lunch. The unpaved road can get dusty and bumpy, so it’s not the spot for a low-clearance hire car if you can avoid it.
Worth it? Yes, for a proper beach day away from the crowds – just budget the extra ten minutes for the access road. See where to stay in Quarteira if you want a base within easy reach.
