Switching from land to boat, this excursion takes you on a three-hour 12km river trip through the densely forested northwestern part of the peninsula. You'll have to duck to avoid the branches at some points, while at others the river opens out into a wide delta-like estuary. Best Advice: Spend an afternoon sailing along this river and observing the peninsula’s rich local wildlife, including an array of rare birds, turtles and crocodiles.
