Head down to this protected peninsula on the Río Paraná for forest walking – there are three marked interpretive trails – and cycling, views from riverside clifftops and beaches. There are several small Guaraní settlements that welcome visitors and sell handicrafts. A local will show you around for a fee or tip.

There is a dedicated zone on the peninsula where you can pitch a tent for free.

Another chunk of wilderness just outside the park boundaries, the Reserva Natural Osusunú is managed by the Fundación Temaikèn, which is working with the local indigenous communities to develop ecotourism here.
