Antunes Beach is situated within the Costa dos Corais, which is the largest federal Marine Protected Area in Brazil.
The beach experiences significant tidal variance, with low tides receding enough to create long, walkable paths through the water toward distant sandbanks.
The sand composition is almost entirely quartz, which accounts for its brilliant white appearance and lack of heat retention compared to volcanic or darker sands.
The shallow depth of the water at low tide makes the beach a primary destination for families with small children.
Local ecological regulations prohibit the feeding of fish or touching coral formations to protect the sensitive reef ecosystem.
Antunes Beach is a coastal stretch in Maragogi, Alagoas, characterized by calm, shallow, crystal-clear turquoise waters and extensive sandbanks exposed during low tide. The beach infrastructure is dominated by casual beach cafes that offer umbrella and chair rentals, along with food and beverage service directly on the sand. The seabed features fine white sand that remains firm, allowing visitors to walk far out into the ocean during the lowest tidal cycles. Local establishments are concentrated along the shoreline, providing essential seating and amenities for day-trippers. The region is part of the Costa dos Corais, Brazil's largest coral reef environmental protection area. Sea temperatures remain consistently warm year-round, suitable for swimming and wading. The beach is widely recognized for its resemblance to Caribbean-style coastal environments.

Consult the official tide table (Tábua de Marés) for Maragogi before visiting, as the beach's visual appeal and walkable sandbanks only appear during low tide.
Bring reef-safe sunscreen and protective water shoes, as parts of the seabed may contain small pieces of broken coral or sea urchins.
Arrive early in the morning to secure a prime chair rental spot, as the best locations at the popular beach cafes fill up rapidly by mid-day.
Do not visit during high tide, as the water rises significantly to the tree line, leaving almost no dry sand for lounging.
Beachwear is appropriate; keep noise levels low; do not leave trash on the sand or touch the coral.
