Located at the northern tip of Ilha Grande between Macacos and Comprida islands, Lagoa Azul (Blue Lagoon) is not a lagoon in the geological sense, but a breathtaking cove with calm, shallow, transparent waters that resemble a massive natural swimming pool.

Its name pays homage to the iconic 1980s movie classic and honors the vibrant turquoise shade of its waters, which contrast beautifully with the dense green Atlantic Forest. It is an absolute must-see and one of the most visited spots in the entire Angra dos Reis bay.

Below is everything you need to know to plan your trip to Lagoa Azul: how to get there, types of boat tours, what to pack, and how to make the most of your experience.

What to Do at Lagoa Azul?

1. Snorkeling and Swimming with Tropical Fish

The main draw of Lagoa Azul is its water clarity. Upon entering the water, hundreds of sargentinho fish (sergeant majors, recognizable by their yellow-and-black stripes) swim right up to visitors. Bringing your own mask and snorkel allows you to explore marine life, corals, and starfish at your own pace.

2. Relaxing on Floating Platforms

Several anchored boats and floating bars in the area serve drinks, caipirinhas, and fresh seafood right to swimmers in the water, making it easy to float and soak in the surroundings for hours.

How to Get to Lagoa Azul

Because there are no direct roads or conventional hiking trails (trilhas) connecting Vila do Abraão to Lagoa Azul for a daily excursion, the only way to reach it is by boat.

The main tour options departing from Vila do Abraão (the island's main hub) include:

1. Flexboat or Speedboat Tours (Recommended)

• Travel time: 20 to 30 minutes from Abraão.
• Pros: Nimble vessels carrying 10 to 20 passengers that reach the spot before larger tour boats. They usually cover circuit tours (like Meia Volta or Volta Completa), stopping at Lagoa Verde, Saco do Céu, and Praia da Feiticeira.

2. Schooner Tours (Escunas - Traditional Large Boats)

• Travel time: 45 to 60 minutes from Abraão.
• Pros: The most budget-friendly option. Schooners feature onboard bars, restrooms, and music.
• Cons: Higher passenger capacity and slower transit speeds.

Local tip: Staying near Freguesia de Santana or Saco do Céu allows you to hire a private water taxi or rent a kayak to arrive early before commercial tour boats pull in.

Practical Tips for Your Visit

• Best time to visit: Tour boats crowd Lagoa Azul between 11:30 AM and 2:30 PM. For a quieter experience, take a private boat or water taxi to arrive before 10:30 AM.
• Snorkel gear: While most tours rent or provide masks and foam floating tubes, bringing your own gear ensures maximum comfort and hygiene.
• Reef-safe sunscreen: To protect this fragile marine ecosystem, wear UV-protective rash guards or use reef-friendly sunscreen.
• Water shoes: Sea urchins rest near rock formations and coral patches; wearing water shoes or neoprene booties helps prevent injuries.

Frequently Asked Questions (FAQ)

Is there a sandy beach at Lagoa Azul?

No. Lagoa Azul is an open sea cove framed by rocky islets and jungle. Boats anchor directly in the natural pool, and visitors jump straight into the water from the deck.

Can you visit Lagoa Azul with children?

Yes, it is a fantastic activity for families. The waters are calm like a swimming pool, and almost all tour operators provide life jackets and floating tubes for kids.

When is the best time of year to visit?

Summer months (December to March) bring warm waters but larger crowds. From April to June and September to November, you will find excellent underwater visibility, sunny days, and fewer boats.
