We went to Ilha do Pelado on the second day of our trip and returned the third day as well! The beach is very tranquil and we easily found our own private stretch. Once you get to Sao Goncalo it costs 15R roundtrip to get there on a small boat. Once you are on the island there is a small hut for snacks and drinks--we favored the cold coconuts. I would absolutely recommend visiting this island!
