One of the smaller beaches on Ilhabela, but totally worth checking out. We went during a fairly slow time so the beach never got too crowded but I would recommend getting there a bit early in case the crowds do show up. There are plenty of chairs/tables to claim your spot at if you like with servers handing out menus for food/drinks. They work at the restaurants across the street and they were very helpful but not pushy. You don't HAVE to order something if you are sitting at the tables.
Look directly across the beach and you will see Ilha das Cabras (Cobra Island.) It is a beautiful sight. You can rent kayaks and snorkel gear among other things to use at the beach. The prices are very reasonable. We rented snorkel gear and kayaks. You can kayak all the way around the island and you can swim wherever you like with the snorkels. You can swim all the way over to the island. The people in charge of renting the equipment don't care where you use it as long as you get it back to them. There was plenty to see while snorkeling and the kayaks were a lot of fun. I absolutely recommend checking this out!
