The bay is a recognized habitat for the Sotalia guianensis species, commonly known as the Guiana dolphin.
The area is part of the Arvoredo Marine Biological Reserve's influence zone, which helps maintain water quality.
The coastline is known for its high concentration of quartz, which affects the local sand composition.
The beach is sheltered from the prevailing south winds, creating a natural microclimate with calmer surf compared to the open ocean.
Praia da Armação, often called Baía dos Golfinhos, is a secluded beach located on the northern coast of Governador Celso Ramos, Santa Catarina. The beach is characterized by its protected, calm waters resulting from its position within a sheltered bay. It serves as a natural sanctuary frequently visited by schools of dolphins, which gives the location its name. The shoreline is framed by dense Atlantic Forest vegetation and granite rock formations. Accessible primarily via hiking trails or boat, the beach lacks large-scale commercial infrastructure, maintaining its natural character. The seabed is primarily sandy with gradual depth, making it suitable for swimming. It functions as a quieter alternative to the more heavily trafficked beaches in the Florianópolis metropolitan area.
From the trail viewpoint looking down into the bay before descending to the sand.
Wear sturdy hiking footwear if accessing the beach via the coastal trail, as the path can be uneven.
Bring sufficient water and snacks, as there are no shops directly on the sand.
Use a dry bag to protect electronics if arriving by boat or swimming in from a vessel.
Attempting to reach the beach by car, as there is no vehicle access to the shore; avoid visiting during peak weekend afternoons if seeking solitude.
Practice 'Leave No Trace' principles by removing all trash; avoid feeding or approaching the dolphins by boat.
