When it comes to pristine waterholes, you are spoiled for choice in the Red Centre. But if you can only visit one spot in Central Australia, make it Trephina Gorge Nature Park – home to sheer quartzite cliffs, a stunning rockhole, and the largest ghost gum in Australia. 

Situated in the East MacDonnell Ranges, Trephina Gorge is the perfect distance from Alice Springs for a day trip – or if you want to stay the night you can choose from one of three camping spots to sleep under the desert sky. This lesser-known nature park spanning 85 kilometres is significant to the Eastern Arrernte people because it is part of the sacred Wallaby Dreaming Trail, and was also once part of the early settlement of the Red Centre. 

From the must-do walks to the best camping spots, here’s your guide to visiting Trephina Gorge Nature Park. 

Things to do at Trephina Gorge Nature Park

Home to two gorges, Trephina and John Hayes, the park boasts walks for every age group and fitness level. Spend your days here scrambling up to lookouts, finding Australia’s largest ghost gum (best viewed in afternoon light), swimming, camping, and taking day trips to nearby N’Dhala Gorge Nature Park, Corrobboree Rock Conservation Reserve, and Arltunga Historical Reserve.  

Walks at Trephina Gorge

To warm up the legs, kick off your Trephina Gorge adventure with the Gorge Stroll, an easy 20-minute jaunt that takes you into Trephina Gorge along a sandy creek bed to the waterhole.   

To take it up a notch, opt for one of the three longer walks: Trephina Gorge Walk, Panorama Walk (both of which take one hour), or the challenging Ridgetop Walk to John Hayes Rockhole, which will keep you busy for four to five hours.   

Both the Trephina Gorge Walk and Panorama Walk will immerse you in gorge scenery from the creek level and showcase the gorge from both rims. Here you will see river red gums lining the sandy creek and ghost gums growing precariously on the rocky ledges above the waterhole. Look out for blank-flanked rock wallabies and birds, including Pacific herons, black-fronted plovers and fairy martins. The slightly longer Panorama Walk will take you on an uphill stretch to a high point where you will be rewarded with stunning panoramic views.   

For experienced walkers, the 9km one-way Ridgetop Walk to John Hayes Rockhole offers spectacular views of the rugged East MacDonnell Ranges. Keep an eye out for the rare Thozet’s Box (Eucalyptus thozetiana) and wildflowers, including holly grevilleas, desert hibiscus, mulla mulla, hop bushes and cat’s tails.   

John Hayes Rockhole

John Hayes Rockhole is a popular swimming spot with icy cold water. However, during prolonged dry periods, the waterholes at Trephina Gorge and John Hayes Rockhole can evaporate, leaving only a sandy creekbed.  

From John Hayes Rockhole, you can set out on the 3.5km loop Chain of Ponds Walk. It starts with an easy 20-minute walk to the rim of the narrow gorge, offering spectacular views and continues on with some difficult climbing and scrambling that’s well worth the effort for the stunning views.  

Trephina Gorge Camping

At the Trephina Bluff, Trephina Gorge and Panorama campgrounds you will find toilets, picnic tables, drinking water, communal firepits, and gas barbecues. John Hayes Rockhole Campground has the same facilities, except for the drinking water. 

 Day trips from Trephina Gorge

If you’re camping at Trephina Gorge, you can use your camp as a base to visit nearby Arltunga, the site of Central Australia’s first town, N’Dhala Gorge, a cultural treasure with 6,000 rock carvings, and the remote Ruby Gap Nature Park, the site of Central Australia’s ruby boom.
