The beach is sheltered by an artificial reef system designed to reduce wave energy and erosion.
The water temperature here is typically 2-3 degrees Celsius warmer than beaches further west due to the influence of the Mediterranean and the shallower coastline.
The sand at Praia da Alagoa is composed of fine, pale silicate grains rather than the coarser, darker sand found elsewhere in the region.
The surrounding dunes act as a natural reservoir and windbreak, preserving a unique micro-ecosystem of endemic flora.
Archaeological surveys in the wider Altura region suggest the proximity to the coast has been utilized for maritime trade since Roman times.
Praia da Alagoa, often referred to as Praia de Altura, is a Blue Flag beach located in the eastern Algarve region of Portugal. The beach is characterized by its exceptionally wide stretch of fine golden sand and calm, warm Atlantic waters. Unlike many neighboring Algarve beaches, Alagoa is backed by low-lying dunes and pine forest vegetation rather than steep cliffs. The shoreline features a gradual depth transition, making it particularly popular for families with young children. During low tide, the receding water creates expansive sand flats and shallow tidal pools. The area is part of the Sotavento coast, which generally experiences higher water temperatures than the western Algarve. Extensive wooden boardwalks provide protected access across the fragile dune system to the shoreline. The beach maintains a Blue Flag status, indicating high water quality and environmental management standards.

Visit during low tide to walk the expansive, flat sandbars that stretch far out into the ocean.
Utilize the designated wooden walkways strictly, as the dune vegetation is protected and fragile.
If the main beach area feels crowded, walk 10-15 minutes eastward toward the quieter sections bordering Praia Verde.
Walking through the dune system outside of the marked wooden pathways, which is discouraged for conservation reasons.
Lifeguard services are typically active only during the official bathing season, generally from June through September.
Use the provided waste bins to maintain the Blue Flag environmental standard; avoid stepping on or disturbing the dune vegetation.
