Ilhabela is an archipelago off the northern São Paulo coast, some 6 km from the mainland, whose main island is officially called Ilha de São Sebastião. It is the largest sea island in Brazil: more than 40 beaches ring the island, more than 300 cachoeiras hide in the forest and close to 85% of the territory is protected within the Parque Estadual de Ilhabela. Two worlds coexist here: the west side, facing the channel and the mainland, with quiet beaches, kiosks, restaurants and almost all the infrastructure; and the east and south, wild and open to the ocean, reachable only by trilha, boat or 4x4.
It is a destination for anyone who wants to mix beach with serious nature. On one trip you can spend the morning in a natural pool opposite the Vila, the afternoon climbing to a cachoeira and, the next day, take on a trail of several hours to an almost deserted beach such as Bonete or Castelhanos. It is also the 'National Capital of Sailing' (a title held by law since 2011, thanks to the winds in the channel) and a diving paradise: the bottom of the São Sebastião channel holds dozens of historic wrecks, including the famous liner Príncipe de Astúrias.
Getting there is part of the ritual: there is no bridge, so you cross by ferry from São Sebastião, a short trip of about 20 minutes. That gives the island the air of a refuge. On the flip side, you have to plan around the ferry timetable in high season and on public holidays, and bring repellent: the borrachudos (a tiny mosquito from damp areas) are Ilhabela's classic nuisance, especially in summer. Pick the right time of year and it is one of the loveliest and most complete places in southeastern Brazil.
The island was called Maembipe by its first peoples and renamed São Sebastião by the Portuguese expedition that arrived on 20 January 1502 (with Amerigo Vespucci on board). It was a refuge for pirates and corsairs, the setting for the sugar cane cycle with dozens of mills and enslaved labour, and only in the 20th century did it turn into the tourist destination it is today. The full story, with its theories and treasure legends, is on the Ilhabela history page.

Origins, formation and what the sources say.
Long before any Portuguese name existed, the archipelago's main island was known to the Tupi-speaking first peoples as 'Maembipe', a place name usually translated as 'hidden place' or 'thing that shines on the water', and one that described that green mass rising opposite the mainland rather well. The Tupinambá and other coastal groups came to its beaches and coves to fish and forage, and left traces on the island such as sambaquis (shell mounds) and rock inscriptions that are still being studied. For them, Maembipe was part of a coastline known and travelled centuries before the Europeans arrived.
The name that finally stuck came from the first Portuguese survey expedition to sail this coast after Pedro Álvares Cabral's voyage. Tradition has it that on 20 January 1502 —Saint Sebastian's day in the Catholic calendar— the sailors sighted the island and named it 'Ilha de São Sebastião', after the saint of the day. On board that 1501-1502 expedition travelled the Florentine Amerigo Vespucci, whose accounts helped spread the image of these new lands in Europe. The same saint would later give his name to the town that grew opposite, on the mainland: São Sebastião.
For centuries the island and its sister town on the mainland shared a history and a patron saint. The current name, 'Ilhabela' ('beautiful island'), is much more recent: it caught on in the 20th century as a tourist and administrative designation, when the municipality officially adopted that evocative name for the island and the archipelago. So the destination carries in its place names the three layers of its history: the Tupi 'Maembipe' of the first inhabitants, the 'São Sebastião' of the Portuguese colonisers and the luminous 'Ilhabela' of the modern era.
The island's position, right on the sea route between the south and the centre of the colony, and the natural shelter its coves offered turned the São Sebastião channel into a classic setting in the pirate and corsair history of the South Atlantic. Through the 16th and 17th centuries, when the Portuguese and Spanish were disputing control of the seas with English, French and Dutch sailors, the hidden coves of Maembipe served as refuge, hideout and watering point for vessels that preyed on ships laden with riches.
Local tradition links the island to legendary names of piracy. It is said that corsairs such as the Englishman Thomas Cavendish, who ravaged the Brazilian coast in the late 16th century, put in around these waters; and popular memory fills the most isolated beaches —such as Bonete or Castelhanos— with stories of buried treasure and loot hidden among the rocks and the forest. Although much of that belongs more to legend than to documented history, it reflects a real background: for a long time the archipelago was a passage for foreign ships, smugglers and adventurers.
That same geography of a narrow channel, strong winds and treacherous currents came at a cost: over the centuries, dozens of vessels sank in its waters. That is why Ilhabela is known today as Brazil's 'capital of shipwrecks'. The most famous of all is the Spanish liner Príncipe de Astúrias, an enormous passenger ship that sank off the Ponta da Pirabura on 5 March 1916, in one of the greatest maritime tragedies in Brazilian history, with hundreds of victims. Today those wrecks, along with those of earlier eras, form artificial reefs and have made the island one of the country's great diving destinations, where the history of shipwrecks and legends lives on underwater.
From the 17th century, and strongly in the 18th and 19th, the economy of the Ilha de São Sebastião revolved around growing sugar cane. The warm, humid climate, the fertile soil on the slopes and the abundant water from countless waterfalls made the archipelago a favourable place for engenhos, the mills where cane was crushed to produce sugar, molasses and, above all, cachaça (cane spirit). At its height the island had dozens of mills spread along its west coast, the side facing the mainland.
As across all of colonial sugar-growing Brazil, that system of production rested on slavery. Thousands of enslaved Africans were brought to the island to work on the plantations and in the engenhos, in extremely harsh conditions. From that enslaved population and its mixing with indigenous people and Portuguese came much of the caiçara culture —that of the traditional coastal settler— which still today defines the identity of the island's communities, such as those of Bonete or Castelhanos, with their small-scale fishing, their food and their traditions. Because of its isolation, the island was also a refuge for enslaved people fleeing the estates, which is linked to the formation of quilombos in the region.
Visible evidence of that sugar past remains. The most notable is the Parque Fazenda Engenho d'Água, an old mill from the colonial period, now listed as heritage, where the main house, the stills, the water wheels and the gardens that recall estate life are preserved. With the abolition of slavery in 1888 and the decline of sugar in the face of other regions, the mills closed one by one, and the island entered a long period of subsistence farming and fishing, before its tourist rebirth in the 20th century.
After the fall of sugar and the abolition of slavery, the Ilha de São Sebastião remained for decades a remote, quiet corner of the northern São Paulo coast, inhabited by caiçara communities living from fishing, small subsistence plots and foraging. With no bridge to the mainland and precarious internal roads, the island kept a slow pace of life for a long time, almost outside the rapid growth of São Paulo state. That isolation, which at the time meant economic backwardness, ended up being its greatest treasure: it preserved nature and local traditions almost intact.
The change began in the second half of the 20th century. The arrival of a regular ferry service between São Sebastião and the island, and better roads linking the northern coast with the state capital, gradually brought the first holidaymakers. The beauty of its more than forty beaches, its hundreds of waterfalls and its clean sea began to draw families, sailors and nature lovers. Little by little the island's old name of São Sebastião gave way, in everyday and tourist use, to the evocative 'Ilhabela'.
Alongside that grew the awareness that this paradise had to be protected. In 1977 the Parque Estadual de Ilhabela was created, and it now shields close to 85% of the archipelago's territory: almost virgin Atlantic rainforest, peaks such as the Baepi, hundreds of cachoeiras and enormous biodiversity, recognised as a biosphere reserve. So the island struck a difficult balance: becoming one of the most sought-after beach and nature destinations in southeastern Brazil without entirely losing its caiçara soul or clearing its forest.
If one activity defines the modern identity of Ilhabela, it is sailing. The reason is purely geographical: the São Sebastião channel, that arm of sea some 6 kilometres wide separating the island from the mainland, works like a funnel that accelerates and channels the winds, generating strong, steady breezes for much of the year. Those conditions, which in the past wrecked so many ships, are a dream for racers today: few areas in Brazil offer wind so regular and so usable for sailing.
That maritime calling was officially recognised. In 2011 a law granted Ilhabela the title of 'National Capital of Sailing', confirming what was already a reality: the island as the centre of sailing in the country. Yacht clubs, sailing schools and operators are concentrated in the channel area, and water sports —from the racing yacht to stand-up paddle and kayaking— are part of the everyday landscape of the west coast.
The big event on the calendar is the Semana Internacional de Vela de Ilhabela, one of Brazil's leading offshore sailing regattas and one of the largest in Latin America, usually held between July and August. Born in the 1970s, it brings together hundreds of boats each year and racers ranging from amateurs to Olympic athletes and world champions. During those days the island is transformed: it fills with crews, flags and spectators, and the channel is covered with white sails. The regatta is also an international showcase that helped establish Ilhabela's reputation as a first-rank sailing destination.
The natural history of Ilhabela is as much a protagonist as the human one. The archipelago is mostly covered in Atlantic rainforest, one of the richest and at the same time most threatened biomes on the planet. Unlike much of the Brazilian coast, where the original forest was cleared, on Ilhabela the combination of mountainous relief, isolation and legal protection allowed an enormous and almost untouched portion of this forest to survive, with its characteristic wildlife and plants, endemic species included.
The most celebrated feature of that nature are the waterfalls: it is reckoned there are more than 300 cachoeiras hidden in the forest, fed by the rain that falls on the island's hills. From small, easily reached drops, ideal for cooling off, to imposing falls such as the Cachoeira do Gato —some 46 metres high, near Castelhanos— the waterfalls are an essential part of the island experience and a reminder of why the old mills prospered here with so much water available.
Protection of that heritage was formalised with the creation of the Parque Estadual de Ilhabela in 1977, which covers close to 85% of the archipelago's territory (more than 27,000 hectares) and forms part of the Atlantic Forest Biosphere Reserve recognised by UNESCO. The park shields peaks such as the Baepi (1,048 m), wild beaches reachable only by trail or boat, and a network of paths for walking the forest. Thanks to that decision, Ilhabela is today a rare example of a mass tourist destination coexisting with a largely preserved ecosystem, where human history —indigenous, colonial, caiçara— and natural history are interwoven at every step.
