It is one of the most famous beaches on the Brazilian coast, especially among the surfing community. Its location 2.5km ocean beach of white sand, with waves have made it a favorite among Cariocas surfing. Today it's a deserted beach with no buildings, and there's only food and beverage service during summer. Islanders come with their beach coolers loaded with soft drinks, beer and food to sell to surfers and swimmers. Swimming can be a bit dangerous because the currents are very strong , but it's shallow enough that if you're cautious if you want to cure a hangover. It's reached by a path from Abrao. You can ride a bike, about 8km, or go by boat.
There are two options to get to this beach: by boat or across all Ilha Grande from Vila do Abraão through a path. It's not as well-known as other beaches like Lopes Mendes (perhaps because of its inaccessibility), Dois Rios has clean water, it's quiet and there are less people in the water. Nearby you can visit the old prison, with two exhibits, one devoted to the prison and the other is objects made from recycled materials.
The last day of my ten day trip to Ilha Grande was quiet, enjoying the beaches and Pouso Palmas, which are on the way to Lopes Mendes from Abrao. The beaches that make up the bay are Grande de Palmas, Mangues, Pouso, Aroeira, Recife and Isla de Palma. In Las Palmas they still have the remains of cannons and ruins of the Ilha Grande era which was one of the strategic defense points of Rio de Janeiro. It was a pretty important town, but today it's a small settlement where they don't even have electricity. Palmas Beach has a campground that is very popular in the summer and small stores that sell drinks and sandwiches. Most of the inhabitants are fishermen, but there are some inns for visitors.
We arrived at Parnaioca after walking down the Praia do Demo, named for the slippery rocks where if you slip you go "straight to hell", then we came to the do Sul and Leste beaches, which are separated by a rocky islet and a lagoon. It's an absolutely fascinating landscape with 4 km of white sand with extremely restricted beach access due to the biological reserve rules. The beach is 1 km long but the sand isn't much compared to the other beaches we passed. You can stay in a campsite near the gorgeous Parnaioca river. There are remains of old plantations where slaves worked the cassava and coffee fields. Today not many people live here.
