The 'Mar de Dentro' (Sea of the Inside) is separated from 'Mar de Fora' (Sea of the Outside) by a narrow strip of land only 800 meters wide.
The bay serves as a primary landing site for local 'mullet' fishing during the seasonal migration period.
The water temperature here is consistently warmer than the neighboring Atlantic-facing beaches due to the lack of cold deep-water currents.
The seabed is gradual and low-gradient, allowing visitors to walk tens of meters into the ocean with water remaining at knee or waist level.
The surrounding landscape is part of a granite-based geological formation that creates a natural barrier against heavy Atlantic waves.
Praia do Canto Grande - Mar de Dentro is a sheltered bay located on the inner side of the Mariscal peninsula in Bombinhas, Santa Catarina. The beach is characterized by its exceptionally calm, shallow, and warm waters, making it distinct from the surf-heavy 'Mar de Fora' side. It serves as a traditional hub for local artisanal fishing, often featuring colorful wooden boats anchored in the bay. The shoreline is composed of fine white sand and is lined with local residences, restaurants, and small inns. Because it faces the inner bay towards the mainland, the water remains protected from strong ocean swells and oceanic winds. The area is a departure point for boat excursions heading to the Ilha do Arvoredo biological reserve.

Visit during low tide to experience a significantly wider sandy beach area.
Bring water shoes if planning to walk near the boat moorings, as the seafloor can occasionally have discarded shells or pebbles.
Use the local kayak and stand-up paddleboard rentals to explore the calm bay waters safely.
Do not attempt to swim in the areas marked for boat traffic and artisanal fishing nets, as the underwater lines are difficult to spot.
Casual beach attire is standard, but please remain respectful of local fisherman and their equipment, which is often stored on the sand.
