Douglas-Apsley National Park, Nature reserve in Glamorgan-Spring Bay, Australia.

Douglas-Apsley is a large nature reserve featuring river gorges, waterfalls, and expansive eucalyptus forests across its terrain. The landscape includes numerous natural swimming holes and varied environments for exploration.

The area received protection in 1989, preserving one of Tasmania's remaining dry forest ecosystems from logging and mining activities. This action safeguarded a forest type that had become scarce elsewhere in the region.

The park's cultural story is one of resource use rather than Indigenous tradition: from the mid-19th century tracks were cut through the wild catchment for mineral prospecting, and coal was mined here for over 100 years. Farming, trapping and mining kept large-scale forest clearing in check, leaving the varied forest that survives today.

Visitors can stay at designated camping areas near Apsley Waterhole where basic facilities are provided. Walking trails of different difficulty levels accommodate various fitness and experience levels.

BirdLife International named the park an Important Bird Area because it supports 11 of Tasmania's endemic bird species, along with flame and pink robins and probably swift parrots. The park also holds dry eucalyptus forest, rainforest, heathland and waterfalls across its 16,080 hectares.
