Ilhéus has the biggest coastal extension among all the cities in Bahia, and that means only one thing, lots of beaches to see. Another great side of this place, is it´s history. In the past Ilhéus was the biggest "cacau"(cacao bean, cocoa bean) exporter in the world, that changed after the farms were infested with a fungus, causing it´s production to decline. But the signs of the past are still in the city, where you can find the old "Casaroes"(Big Houses) where the Baron´s of cacau used to live. If you want you can also see some of the places where the cacau´s high society used to meet, by visiting the Bar Vesuvio and the Cabaret Bataclan.
Another interesting thing about Ilhéus is that it has inspired famous brazilian writer Jorge Amado. He mentions places like Bar Vesuvio in his work, and lots of other location in the city. So if you are a fan, you can´t miss this oportunity to see the house of Jorge Amado, now it´s known as "Casa De Cultura Jorge Amado"(House of Culture Jorge Amado).
You may also take a guided tour through the cacau´s farms. Where you can lear about the production of this fruit, most important ingredient in chocolate. By the way there´s also a chocolate factory you can visit.
There also a lagoon called "Lagoa Encantada"(Enchanted Lagoon), you can get there by ship, through the Rio Almada. It´s a 14 square kilometers lagoon, and in it´s surroundings you´ll find waterfalls, fisher´s villages, cacau farms and much more. It´s definetly a great place to see.
