Sandwiched between sand dunes, lagoons and the sparkling Atlantic, Cabo Frio's naturally gorgeous setting has been seriously stunted by industry and overdevelopment. The city itself isn't the most attractive, however on weekends and summer holidays its bars and beaches continue to draw crowds of happy-go-lucky Brazilians.
Praia do Forte is the jewell in the crown of Cabo Frio, a stunning stretch of white sand and green waters named after the fort at its eastern end. Along the Canal do Itajuru you can find many restaurants, the canal links nearby Lagoa de Araruama to the Atlantic Ocean.
You can take boat trips departing from Cabo Frio (or Buzios that drive you to Cabo Frio for the boat trip and then back) to some small islands like Comprida Island, boasting wonderfully clear, sparkling blue water.
One of the best beaches in the area - some locals even say the world - is Prainha. Not so easy to access but once you get there it'll be worth it, just amazing...Emerald colour waters, white sand and wilderness so well preserved which will make you feel special. The difficult access preserves its natural beauty.
