I stayed some nights in a camping in Paraty, which is quite close from Ubatuba, in a camping called Camping Portal de Paraty
However, I can't remember the prices, but it was quite cheap. I can't found the prices in their website, but I found this comment where a folk said :
we paid for 2 people 60 reales per day
The comment was posted on June 26th, 2016, so I guess it's still valid
I have very goods souvenirs of this camping, so if it's in your price range and if the location is good for you, you can go there without problem
