Daintree Rainforest, Australia

The World Heritage-listed Daintree Rainforest is about a two-hour drive north of Cairns and can be seen on a day trip from the city or over the course of two days, staying overnight in one of its wilderness lodges. The tropical rainforest is home to the most diverse range of plants and animals on earth, including the rare tree-dwelling kangaroo and the endangered cassowary. Start your day at the Daintree Discovery Centre where you can walk along the 125-metre (410-foot) long Aerial Walkway through the mid-level rainforest or take a self-guided rainforest tour. Join a gentle cruise down the Daintree River to spot wildlife in its natural habitat, including saltwater crocodiles. On foot you’ll find that rainforest meets reef at Cape Tribulation, where you can easily lose hours walking through tropical lowland forest or along stretches of white sand.
