Praia da Adiça is a wide sandy Atlantic beach south of Costa da Caparica, backed by protected dunes. Access is on foot over sand using marked paths, with informal parking near the dune entries. There is no paved beachfront access, and soft sand makes the route unsuitable for wheelchairs. Public transport does not reach the sand directly, so most visits combine travel via Costa da Caparica with a car, taxi or long walk. The beach is free to access with no gates or fixed hours. There are no toilets, showers, food concessions or built shade, so bring water, supplies and sun protection and carry out waste. Most visits last a few hours. June to September is warmest and driest, while winter is cooler, windier and wetter. Atlantic water remains cool year-round, with waves and currents that vary with wind and tide. Morning and late afternoon offer milder sun and wind than midday, but exposure is high and dunes provide only limited wind shelter. Lifeguard coverage is limited and may be absent on remote stretches. Naturism is tolerated mainly in the south, with northern areas more textile. Dogs may be restricted during the bathing season, so check signage. Because facilities are absent, visitors generally arrive prepared for a self-sufficient stay and take everything away on departure. The open layout allows people to spread out, while the dune edge marks the transition from parking and paths to open sand. Conditions can feel quite different between calm mornings and windy afternoons, so timing shapes comfort more than crowding on this quiet stretch.
