Curral beach, despite being one of the best known and most famous in Ilhabela, from my point of view is one of the least recommended.
Despite being a beach with an extensive sand compared to most beaches on Ilhabela, it is a beach with a lot of people, the bars are extremely expensive, very expensive, the parking is all paid and there are not many spaces.
If you like a place with a lot of people, then you are on the right beach, but you should bring your own drinks and food or pay a fortune for lunch.
