We have a dream of camping on a small island on the Parana delta, just a group of friends a few fishing poles and a few days to unwind and swim. Does anyone know of a good campground (private and uncrowded. Not car camping style with hundreds of people camping on a lawn), or of a way to make this happen? Can we just rent a boat and go find a nice spot somewhere or is all the land privately owned? Any tips or suggestions would help, thanks!
