The diverse tropical rainforest habitats of Bellenden Ker National Park are a vital component of the vast Wet Tropics World Heritage Area of northeast Queensland, Australia. Ranging in elevation from 80 metres to the 1622-metre summit of Mt. Bartle Frere, highest summit in Queensland, the lowland rainforest, montane rainforest, vine forest, fern forest, and open grassland ridges of this 79,500-hectare park are a vegetation mosaic that is the result of periodic cyclone damage and altitudinal gradients. The term "rainforest" is apt; annual rainfall at the summit of the park is 9000 mm per year.

Although the wet tropical rainforests of northeast Queensland cover less than 0.1% of the land area of Australia, they are home to 30% of all Australian marsupial species, 60% of all bat species, 18% of bird species, 30% of frog species, 23% of reptile species, and 64% of the butterfly species in Australia.

Activities include dayhiking, backpacking, botanical study, and wildlife observation.

• Hike the rugged trail to the 1622-metre summit of Mt. Bartle Frere, highest point in Queensland.
• Bring binoculars and watch for some of the more than 370 species of birds that occur in the region, including bridled honeyeater, golden bowerbird, and the flightless Australian cassowary.
