The Daintree Rainforest itself meets all four natural criteria on the "Criteria for Selection to be a World Heritage Site", though it is just part of the Wet Tropics site. The Wet Tropics are one of only twelve natural World Heritage Sites in the world which meet all four criteria. The Daintree area is next to another World Heritage site, the Great Barrier Reef. This makes it the only place in the world where two natural World Heritage Sites meet.
