Quick summary
The Ibiraquera Lagoon is one of the most fascinating natural treasures in Imbituba, on the southern coast of SC. Surrounded by white sand dunes, native coastal vegetation (restinga), and traditional fishing villages, it blends high-performance water sports with eco-friendly family tourism. Its calm, shallow, and brackish waters are a safe invitation for toddlers and swimmers, while its steady winds attract sailors from all over the world seeking the perfect setting for kitesurfing and windsurfing.
What makes the Ibiraquera Lagoon a unique ecosystem
The Ibiraquera Lagoon features a singular geographical layout on the Santa Catarina coast, stretching between the municipalities of Imbituba and Garopaba. Separated from the Atlantic Ocean by a wide sandbar, it is fed by both freshwater springs and ocean tides. This unique blend creates a lagoon of brackish water, famous for being significantly warmer, lighter, and more pleasant for swimming than the open waters of the ocean.
Beyond its aesthetic and tourist appeal, this brackish environment holds immense biological importance. The lagoon operates as a natural marine nursery, serving as a habitat for the development of fish, crustaceans, and the famous Ibiraquera pink shrimp. Its shores preserve the living traditions of artisanal net-casting fishing, sustainably practiced by local communities for many generations.
Periodically, the opening of the Barra de Ibiraquera occurs—either through natural causes due to rainfall or via assisted environmental management. This process temporarily connects the lagoon to the open sea, promoting water renewal, allowing new marine species to enter, and temporarily transforming the local water currents and visual landscapes.
Things to do at the lagoon: Family leisure and ecotourism
The geographical features of sheltered waters without waves make the Ibiraquera Lagoon the perfect destination for family travelers, offering relaxing activities that integrate all ages:
- Kayaking trips: An excellent option to explore the lagoon's channels and hidden corners with absolute peace of mind.
- Stand Up Paddle (SUP): The smooth glassy water on calm wind days is perfect for beginners and children to practice their balance safely.
- Safe lagoon swimming: Warm, brackish, and very shallow waters along the shores, ideal for babies and toddlers to play without the undertow risks of the open sea.
- Native bird watching: A true ecological sanctuary where it is easy to photograph herons, spoonbills, sandpipers, and other migratory birds.
- Cinematic sunsets: Sunset at the lagoon is one of the most photographed spectacles in Santa Catarina, as the sky takes on gradient tones reflected on the water.
Wind sports: The perfect arena for kitesurfing, windsurfing, and SUP
For adrenaline and water sports enthusiasts, the Ibiraquera Lagoon is internationally renowned as one of the best arenas on the American continent. The combination of steady winds (especially the Northeast wind), the lack of heavy ocean swells, and shallow depths across extensive stretches creates an unbeatable training ground.
Experienced sailors take advantage of the strong wind for high-speed maneuvers and jumps, while the sheltered waters greatly ease the learning curve for beginner students in local kitesurfing and wing foil schools. During the peak wind season, the Barra sky gains a colorful touch with dozens of kites and sails.
Even for tourists who prefer resting on the sand, the choreography of sails crossing the brackish waters transforms the landscape into a vibrant and unique experience that symbolizes the identity of Barra de Ibiraquera.
Best time to visit and natural phenomena
The destination offers remarkable experiences throughout all four seasons of the year. In the summer months (December to March), the entire focus is on beach tourism, refreshing swims, paddleboarding, and family vacations. The warm weather highlights the lagoon's use as a massive natural outdoor club.
In spring (September to November), the consistency and intensity of the winds reach their peak, officially kicking off the primary kitesurfing and windsurfing season. It is the period when the village buzzes with athletes from all over the world.
During winter and autumn (July to November), eco-walks on the surrounding dunes and nearby elevated lookouts become the perfect setting to combine the lagoon's quietness with Southern Right Whale watching ecotourism, as whales choose the sea right in front to nurse their calves.
Ideal lodging by the lagoon and the sea
Since Barra village developed on a flat peninsula surrounded by these waters, choosing lodging with a full vacation rental setup optimizes the entire experience. Staying in townhouse-style apartments with equipped kitchens allows the family to have total schedule autonomy, secure space to wash and store boards or kitesurfing sails, and the ease of walking a few meters to switch between a dip in the brackish lagoon and a stroll on the beach.

Frequently asked questions
Is the water in the Ibiraquera Lagoon fresh or salty?
The water in the Ibiraquera Lagoon is brackish. It is fed by both freshwater springs and Atlantic Ocean tides. This unique mix makes the water temperature warmer and more pleasant for swimming than the open sea.
Is the Ibiraquera Lagoon safe for young children?
Yes, it is highly recommended for families with children. Its waters along the shores are calm, wave-free, and shallow, functioning as a protected natural pool where little ones can play in complete safety.
Why is the lagoon so famous for learning kitesurfing and windsurfing?
Because it gathers perfect conditions: steady and strong winds combined with water completely sheltered from ocean waves and large shallow areas. This provides beginners with a controlled and safe environment to get up on the board without the strain of the open ocean.
Where can I rent kayaks and stand-up paddleboards (SUP) at the lagoon?
Near the main shores of Barra de Ibiraquera and in the village center, there are local operators and inns that offer hourly rentals for kayaks, SUP boards, and safety equipment during the summer season.
How does the opening of the Barra de Ibiraquera sandbar work?
It is the moment when the sandbar breaks and the channel connects the lagoon directly to the sea. This process occurs naturally with increased rainfall or through planned interventions to balance the ecosystem, allowing fish and shrimp migration and renewing the lagoon's salinity.
