I actually live in Caracas and I am planning a little backpack trip in June to experience Canaima and the World Cup in Brazil. I am thinking about 1 day in either Ciudad Bolivar or Puerto Ordaz, 2-3 days in Canaima. From there I hope to cross the border to Brazil and go to Boa Vista. Finally I am hoping to end in Manaus. Any suggestion about flights, buses, posadas would be greatly appreciated.
