Trephina Gorge Nature Park, Nature park in East MacDonnell Ranges, Northern Territory, Australia.

Trephina Gorge Nature Park is a nature park in the East MacDonnell Ranges featuring red quartzite cliffs and multiple gorges shaped by water erosion over millions of years. The landscape includes steep rock faces and deep valleys with several walking trails that access different sections of the carved terrain.

The area was shaped millions of years ago through geological processes that created the quartzite and sandstone ridges visible today. Water erosion over extended periods carved the gorges and valleys into these massive rock formations.

The gorge's Eastern Arrernte name is Alherrkentye. In September 2008 the land was transferred to the Atnerrperrke Aboriginal Land Trust for its traditional owners, who then leased it to the Northern Territory government for 99 years so it could remain a nature park.

The park offers five marked walking trails with varying difficulty levels, such as the Chain of Ponds Walk and the Panorama Trail, connecting different sections of the gorge. Visitors should bring plenty of water and be prepared for changing conditions, as the trails are exposed with little shade.

The gorge's name comes from Trephina Creek, believed named after Tryphina Benstead (née Rains), wife of William (Bill) Benstead, manager of Undoolya Station from 1877 and the first licensee of the Stuart Arms Hotel in Alice Springs. The Eastern Arrernte name for the gorge is Alherrkentye.
