Saltwater crocodiles, the largest living reptiles in the world are found abundantly in Australia and guided tours at different locations are set to spot these creatures as well as other wildlife in their natural habitat. Crocodile spotting tours in Cairns typically involve a boat or kayak ride through areas where crocodiles are known to live. Visit the Daintree Forest and River, Mitchell River National Park, Wet Tropics World Heritage Area, Rainforest Nature Park in Kuranda, and Hartley’s Crocodile Adventures for an up-close encounter.
