Morton National Park, Nature reserve in New South Wales, Australia.

Morton National Park is a nature reserve between Sydney and Canberra containing sandstone cliffs, eucalyptus forests, deep valleys, and multiple waterfalls. The terrain varies considerably with different elevation zones and landscape types throughout the area.

The area became a protected national park in 1938, named after Mark Morton, a state politician who advocated for protecting this land. This designation marked a key moment in preserving the region for the future.

The Yuin people hold the park and the surrounding country, including Didthul (Pigeon House Mountain), as central to their mythology. The park lies within a landscape estimated to have been inhabited by Aboriginal people for almost 20,000 years. Didthul is the name the mountain carries in Yuin tradition.

Fitzroy Falls sits beside the main road linking the Southern Highlands with Kangaroo Valley, so it is the easiest section to reach by car. Pigeon House Mountain, west of Milton, is climbed on foot and the plateau's steep gorges make walking conditions change quickly. Carry water and wear sturdy footwear.

The park's two camping grounds, Dunghaven and Beorgwic, host medieval-style re-enactment life, an activity not usually associated with a New South Wales national park. The park also holds part of the Budawang Range, and the adjoining Budawang National Park lies to its south. Mount Tianjara, at 768 m in the east, is the highest point.
