Paraty is said to have been built to be flooded. The story goes that the Portuguese laid out the streets of this port just above sea level, and when the tide runs high around the full moon, the bay still comes up through openings in the sea wall and washes the cobbles clean. Shopkeepers put out little footbridges and everyone carries on. Whether it was planned that way is local lore, but the floods are real. The town's fortunes began with the gold years: in the 1700s, Paraty was where gold from the mines of Minas Gerais came down the mountain on mule trains, the so-called Caminho do Ouro, to be shipped to Portugal. When the gold ran out the town lived on sugar cane, cachaça and, in the 1800s, coffee from the Paraíba valley. A railway along that valley took the coffee trade away in the 1870s, the port was forgotten, and that neglect is why the colonial center looks so little changed. In 2019 UNESCO listed Paraty together with Ilha Grande as a mixed site, for culture and for the Atlantic forest around it.
Ilha Grande is the other half of the story and a very different place. It's a forested island of about 193 square kilometers, a short boat ride off the coast, with no roads and no cars, only trails, beaches and one real village, Vila do Abraão. It has a dark side too: a quarantine station and then a maximum-security prison, closed only in 1994, kept it half off limits for most of the 20th century, and that is partly why so much forest survived. Together the two make the best-balanced short trip on the Costa Verde, the "green coast" between Rio de Janeiro and São Paulo: a day-and-night town you can walk in an hour, and a wild island where you walk because there is no other way.
This plan spends three nights in Paraty and two in Abraão, which is the minimum for both, and it starts on a Wednesday, when the Casa da Cultura, the church museum and the fort museum are all open. Day one is the colonial center, day two (Thursday, a weekday bus) the beaches and rock pools of Trindade, day three a schooner across the bay, day four, a Saturday, waterfalls and a cachaça distillery before the boat to the island, and day five, Sunday, Lopes Mendes beach and the village. Monday morning is the boat back. More about Brazil as a whole is on the Brazil country page.
