Is Ilha Grande worth visiting? A verdict by traveler type

For most trips the answer to whether Ilha Grande is worth visiting is yes, with one condition: match the way you go to the thing you want. The island is large and green, and it is protected, which shows in how the day goes. There is no road to the island, the sea is clear in the sheltered bays, and a big part of the pleasure is walking from one beach to another.

The condition is time. A boat day from Rio gives you lagoons, snorkeling and a lunch, and it is a good way to taste the coast in a single day. The island itself, with its trails and villages, needs a night or more, and an overnight stay is where the effort of getting there pays back. Read this page with that split in mind.

If your interest is nightlife, shopping or city sights, the island is a weaker fit, and the protected status of the park shapes the island. For nature, swimming and quiet, it is a strong choice on this coast, and the paragraphs below test that claim against the numbers and the official advice before you commit a day or a night.

Swimmers and snorkelers are well served: at the Blue Lagoon visitors swim, float on noodles and watch fish, and the shallow, calm Green Lagoon holds greenish corals that the portal calls rare on the planet.^21,22,24 It suits walkers, because the state park rates the paths from light to intense and gives times for each.^8,20

It suits history readers too. The Lazareto quarantine hospital operated from 1886 to 1913, the Candido Mendes penal colony closed in 1954 and was demolished in 1961, and the Dois Rios prison worked from 1903 to 1994.^9,25,26 The ruins are among the island's relics, along with the Santana church and the Castelhanos lighthouse.²⁷

It suits fewer people who want comfort without effort or who need to be near a city. Every route ends on a boat, the main village is small, and the farther beaches take walking or another boat.^28,7 Travelers with limited mobility should look at the access notes on each listing, because several of the speedboat tours are not recommended for them.

Paraty is the usual alternative, and it works as a pair. Paraty, says the state tourism portal, has a bay of 50 beaches, some on the road and many reachable only by boat, plus a historic center that kept its 18th-century plan and much of its colonial architecture.^5,6 A walking tour of that center with a cachaça tasting lasts 1.5 hours and starts from $18.

Paraty also joined the UNESCO Creative Cities Network as a city of gastronomy on 31 October 2017.³⁶ Pick Paraty if your interests are architecture, food and a walkable town; pick Ilha Grande if you want trails, lagoons and forest. A shuttle of 3.5 hours connects Paraty with Abraão from $65, so the two fit on one trip.

On a short stay in Rio, neither place may be necessary. The state tourism portal counts Ilha Grande among the Costa Verde favorites, and the day trip is the simplest taste of it.²⁸ If the trip feels like too much road for one day, a night in Paraty or Abraão spreads the effort and gives both a better evening.

The day trip suits a single free day in Rio, a wish for a swim and a story, and a taste for having the logistics handled. The tour sold here is 14 hours with pickup and starts from $75. Choose a night on the island if the walks appeal, and plan to arrive early enough to use the afternoon on a short walk or a swim.

Choose both: a day on the water first, then a longer return trip. The first visit works as an orientation, with the lagoons on the north side and the village on the east, and the second as a chance to walk. Pair the plan with a forecast check, because rain makes the paths demand care, as the park notes for the Lopes Mendes path.¹⁷

Booking the day trip costs nothing to undo until the day before, which keeps it a low-risk test. Try the quiz above for a first recommendation, and then read the weather and best time page before you pick a date, so that the forecast and the plan meet. A day with sun and a calm sea is the version of the island you came for.
