Niterói by Boat: Itaipu, Camboinhas & Hidden Beaches

On the other side of Guanabara Bay lies a coastline that most locals still haven't explored from the water. While the beaches of Rio's Zona Sul are packed on weekends, the waters around Itaipu and Camboinhas remain calm, with light-colored sand, pristine nature, and stretches of coast accessible exclusively by boat. Crossing the bay by boat and discovering the ocean side of Niterói is one of the most surprising experiences you can have in Rio de Janeiro.

In this guide, you'll discover every beach along the route, the hidden stops that only those who sail can find, where to have a fresh seafood lunch, and how WeBoat takes you there in comfort and safety. If you've already done the classic trips around Urca and Copacabana, this is your next must-visit destination.

Why Crossing the Bay Is Worth It

Crossing Guanabara Bay by boat is, in itself, a memorable experience. Departing from Marina da Glória, you pass along Aterro do Flamengo, round the Fortaleza de Santa Cruz, and enter the open sea with the Niterói coastline revealing itself ahead. But the true appeal of this route goes beyond the sailing itself.

The beaches of Rio's Zona Sul -- Copacabana, Ipanema, Leblon -- are beautiful, but they suffer from overcrowding, especially in summer. Itaipu and Camboinhas offer a stark contrast: wide beaches, cleaner and clearer waters, preserved sandbank vegetation, and a small-town-by-the-sea atmosphere. It's like traveling to the coast without leaving the metropolitan area.

On top of that, the view back toward Rio is simply spectacular. Anchored in the calm waters of Itaipu, you can gaze upon Sugarloaf Mountain, Christ the Redeemer, and the entire Rio skyline from the other side of the bay -- a perspective that few tourists and residents ever get to see.

Praia de Itaipu: Calm Waters and the Taste of the Sea

Praia de Itaipu is the heart of this route. Stretching approximately 800 meters, it has a charm that blends fishing tradition and natural beauty. The waters are notably calmer than the neighboring ocean-facing beaches, thanks to the natural protection provided by coastal islands and the cove's geography.

As you anchor in front of the beach, you immediately notice the difference: the sand is lighter, the sea shimmers in shades of emerald green, and the landscape is framed by Morro das Andorinhas and the ruins of the old Recolhimento de Santa Teresa atop the rocky headland. It's a scene that seems to belong to a tropical island paradise, not a city of over 500,000 people.

Itaipu is also famous for its fishing village, one of the most traditional in the state. Colorful canoes line the sand, and fresh fish arrives every day. This tradition is reflected in the beachfront restaurants, which serve seafood of exceptional quality -- but we'll get to that a bit later.

Camboinhas: Deserted Beaches and Preserved Nature

South of Itaipu, Praia de Camboinhas offers an even more pristine setting. Stretching about 1.2 kilometers, it is flanked by sandbank vegetation and the Itaipu Lagoon System, a mangrove and lagoon ecosystem that is home to dozens of bird and fish species.

The great advantage of arriving at Camboinhas by boat is being able to access the most isolated stretches of the beach, far from areas reachable by road. On weekdays, it's common to find long stretches of sand that are virtually empty -- a rare luxury on the Rio de Janeiro coast. The waters are crystal clear, with excellent visibility for snorkeling along the rocky headlands at either end of the beach.

For those seeking rest and contact with nature, Camboinhas is the perfect destination. The silence, broken only by the sound of waves and birdsong, creates a retreat-like atmosphere that stands in stark contrast to the bustle of the capital.

Hidden Beaches: Accessible Only by Boat

The true treasure of the Niterói by boat route is the hidden beaches tucked between rocky headlands, inaccessible by land or reachable only by long, steep trails. By boat, you arrive in minutes and have these little paradises all to yourselves.

Prainha de Piratininga

Hidden between the rocky headlands that separate Piratininga from Camboinhas, this small strip of sand is a well-kept secret. Less than 100 meters long, surrounded by native vegetation and rocks, it only receives visitors who arrive by sea. The water is transparent and calm, ideal for swimming and snorkeling. It's the kind of place that makes you wonder how something like this can exist just 20 kilometers from downtown Rio.

Praia de Adão e Eva

Located at the entrance to Guanabara Bay, between the Fortaleza de Santa Cruz and Praia de Boa Viagem, Praia de Adão e Eva is one of Niterói's best-hidden gems. Although it has land access via a trail from Jurujuba, arriving by boat is incomparably more practical and allows you to combine the stop with the rest of the route. The beach has fine sand, calm waters, and a head-on view of Sugarloaf Mountain that will take your breath away.

Lunch Stop: Fresh Seafood in Itaipu

One of the great advantages of the Niterói route is the option to stop for lunch at the restaurants in Itaipu, renowned for their seafood quality. Local fishermen supply the restaurants daily, ensuring the fish, shrimp, squid, and octopus are always fresh.

Here's how it works: the boat anchors in front of the beach, the group disembarks with the captain's assistance and walks just a few meters to the restaurants on the sand. After lunch -- which typically lasts between 1 and 1.5 hours -- everyone returns to the boat to continue the trip. Some highlights from the local menus:

• Moqueca de peixe e camarão (fish and shrimp stew) -- a main dish that feeds two to three people
• Casquinha de siri (crab gratin) -- a classic starter, always freshly prepared
• Peixe grelhado inteiro (whole grilled fish) -- sea bass, mahi-mahi, or namorado, straight from the fishermen's boats
• Camarão na moranga (shrimp in a pumpkin) -- generous portions, perfect for sharing

Another option is to bring your own lunch or book the BBQ on board with WeBoat, prepared by a professional grill master while you enjoy the view. In that case, you can use the time you'd spend at the restaurant to explore more beaches.

The View Back to Rio: A Perspective Few Ever See

If the journey to Niterói is already impressive, the view back toward Rio is simply unforgettable. Anchored in the waters off Itaipu or sailing back across the bay, you get a complete panorama of Rio's most iconic landmarks:

• Sugarloaf Mountain and Morro da Urca -- outlined against the sky, with the cable car passing between the hills
• Christ the Redeemer -- visible atop Corcovado, framed by the Serra da Carioca mountains
• Copacabana Beach -- the perfect curve of the shoreline seen from the sea, with buildings gleaming in the sunlight
• Ponte Rio-Niterói -- the imposing 13-kilometer structure spanning the bay
• Downtown Rio and the port area -- the urban skyline contrasting with the green mountains

In the late afternoon, when the golden sunset light illuminates the city, this view takes on a cinematic quality. It's the perfect moment for photos and videos that will impress your friends and followers. For more on this kind of experience, also read about the best time for a boat trip in Rio.

Crossing the Bay: What to Expect

• Distance: approximately 15 kilometers from Marina da Glória to Praia de Itaipu

Best Time for the Trip

The Niterói route can be done year-round, but conditions vary by season. The best time for a boat trip in Rio is especially relevant for this route, which includes a stretch of open sea:

• November to March (summer): ideal conditions -- calm seas, warm water (24-27°C / 75-81°F), excellent visibility, and long days. This is the best time
• April to May (autumn): still very good, with pleasant temperatures and fewer crowds on the beaches
• June to August (winter): possible on calm-sea days, but with more frequent cold fronts and southwest swells. The view back to Rio on clear winter days is extraordinary
• September to October (spring): conditions improving progressively, a good option for those looking to avoid peak season

Our captains monitor sea conditions daily. If rough seas are forecast for the ocean stretch, we offer free rescheduling or suggest an alternative route within the bay. Check the frequently asked questions page for more information on rescheduling.

Practical Tips for the Trip

To make the most of the Niterói by boat route, follow these recommendations from our captains:

• SPF 50+ sunscreen: the bay crossing and beach stops mean prolonged sun exposure. Reapply every 2 hours and after each swim
• Snorkel and mask: the rocky headlands of Camboinhas and the hidden beaches have excellent visibility for snorkeling. If you don't have your own gear, let us know when booking -- we can arrange it
• Waterproof camera: a GoPro or phone in a waterproof case is essential for capturing the hidden beaches and marine life. The sunset view back toward Rio produces stunning photos
• Light clothing and water shoes: for disembarking on the beaches, neoprene sandals or water shoes protect your feet on the rocks
• Cash: if you plan to eat at the restaurants in Itaipu, bring cash as a backup -- some smaller establishments may not accept cards
• Motion sickness medication: if you are sensitive to motion, take preventive medication 30 minutes before boarding (consult your doctor). The ocean stretch may have swells
• Quick-dry towel: takes up less space and dries between swims
