The beach is formed by a small cove created by natural granite rock outcrops that dissipate wave energy.
It is frequently referred to as a 'hidden beach' by locals because it remains partially obscured from the main street views.
The water clarity at Praia da Joana is generally higher than surrounding beaches due to the lack of heavy sediment agitation by waves.
The rock formations bordering the beach are part of the coastal geological structure of the Macaé formation.
Praia da Joana is a secluded, cove-like beach in Rio das Ostras characterized by its distinct rock formations and calm, emerald-green waters. It is positioned as one of the few beaches in the region protected by a natural breakwater of stones, creating a pool-like environment suitable for swimming. The beach is accessible via a short walking trail from the Costazul area. Despite its proximity to the urban center of Rio das Ostras, the site maintains a quiet atmosphere due to its limited strip of sand and hidden location. The surrounding cliffs provide natural shade during certain hours of the day. It is a favored spot for families with children who prefer sheltered water over the stronger surf found elsewhere on the coast.

Bring your own gear, as there are limited commercial facilities directly on the sand.
Wear water shoes if you plan to walk near the rocky perimeter to avoid sharp surfaces.
Visit during low tide to maximize the available sandy beach area, as high tide significantly reduces the space.
Do not attempt to park directly on the sand or block the narrow access pathways leading from the street.
Pack out all trash to preserve the secluded ecosystem; avoid climbing on the fragile rock formations.
