The beach is fed by the Ribeira de Pêra, which flows from the Serra da Lousã mountain range.
The basin is created by a man-made weir, a common engineering practice for fluvial beaches in the central Portuguese interior.
The water temperature at this altitude is notably cooler than at coastal Atlantic beaches.
The site is integrated into the larger network of 'Praias Fluviais' in the Pinhal Interior region.
Mosteiro's River Beach is a designated fluvial beach located on the banks of the Ribeira de Pêra in the municipality of Pedrógão Grande. The site features a concrete dam that creates a deep, calm water basin suitable for swimming. Visitors have access to a grassy recreational area lined with trees for shade and sunbathing. A café-bar is situated directly on-site to provide refreshments and light meals. The beach infrastructure includes public toilets, showers, and designated picnic zones. Water quality is monitored throughout the swimming season to ensure public safety. Access is provided via a bridge and walking paths that connect the beach area to the surrounding village infrastructure.

Bring water shoes, as the riverbed can be rocky or slippery.
The grassy areas are popular; arrive early on weekend mornings to secure a shaded spot under the trees.
Pack a picnic, as the on-site café can become busy during peak summer afternoons.
Do not attempt to dive from the weir wall, as water depth near the concrete structure varies.
Lifeguard services and water quality testing are active only during the summer bathing season.
Standard beachwear is acceptable; modest attire is recommended when entering the café or walking through the residential village.
