How Hard Is the Kings Canyon Rim Walk? Difficulty, Stairs and Safety

TL;DR: The Kings Canyon Rim Walk is a 6km loop rated Grade 4 (moderate to difficult), and it opens with roughly 500 stone steps. Most reasonably fit adults manage it in three to four hours with rest stops. The climb gets all the attention, but the unfenced cliff edges along the rim are the part that deserves more of your respect.

Two questions come up before anyone books this walk. Can I physically get up those stairs? And is it actually dangerous?

The honest answers: yes, probably, if you can climb a few flights of stairs without stopping to catch your breath. And it’s safe if you stay on the marked path and start early. The Kings Canyon Rim Walk isn’t a technical hike. There’s no scrambling, no exposure you have to climb through, no navigation problem. It’s a steep start followed by three hours of mostly flat walking on sandstone, with a few sections where the ground simply stops and the canyon floor is 100 metres below.

Here’s what the walk actually involves and who should think twice about it.

The climb: “Heart Attack Hill”

The walk starts with roughly 500 stone steps up the side of the canyon. They’re uneven, they’re steep, and there’s no shade on them at all. Most walkers take 20 to 30 minutes to get to the top.

The nickname came from walkers, not from park signage. It stuck because the climb is front-loaded, unshaded and unavoidable, and because people used to hit it cold in the middle of a 38 degree day. Take it slowly and it’s manageable. Stop every 50 steps if you need to. There’s no prize for the fastest ascent, and nobody behind you is in a hurry.

Two things make a real difference. Start early, when the rock is still cool and you’re walking in shade. And drink before you’re thirsty, not after.

What happens after the climb

Once you’re on the rim, the hard part is done.

The terrain flattens out into a wide sandstone plateau. You’re walking on rock rather than a formed track, with markers to follow. There are gentle rises and dips, but nothing like the opening climb.

The only remaining stairs are the descent into the Garden of Eden and the climb back out on the other side. That’s a much shorter set, maybe 100 steps down and a similar number back up, broken up by a shaded waterhole in between. It’s a good place to sit for ten minutes.

Who should think twice

The Grade 4 rating is a fair reflection. This walk is not for everyone, and there’s no shame in choosing the easier option.

If you…	Our take
Walk regularly and can climb stairs without stopping	You’ll be fine. Start early and pace the first 500 steps.
Are reasonably fit but haven’t walked in heat before	Doable. Start before sunrise and carry more water than you think you need.
Have a heart condition or high blood pressure	Talk to your doctor first. The climb is a sustained effort in heat with no early exit.
Have knee or hip problems	The descent at the end is harder on knees than the climb. Consider the Kings Creek Walk instead.
Are travelling with kids under about 8	The unfenced edges are the issue, not the stairs. Most families choose the Kings Creek Walk.
Have limited mobility or use a walking aid	The Rim Walk isn’t accessible. The Kings Creek Walk is the better fit.

The Kings Creek Walk is the alternative worth knowing about. It’s roughly 2.6km return, mostly flat, and it takes you along the canyon floor to a viewing platform looking up at the walls. You still get the scale of the place. You just skip the climb.

Safety on the rim

People search for whether anyone has died on the Kings Canyon Rim Walk, and it’s a reasonable thing to want to know before you commit. Here’s the practical version.

Sections of the rim have no guardrails. The marked path keeps you a safe distance from the edge, and the rock is stable and grippy underfoot. Almost every serious incident on walks like this involves someone stepping off the path for a photo, usually near an edge where the sandstone is undercut and you can’t see what’s beneath you. Don’t do it. The photo from the marked lookout is the same photo.

Heat is the bigger risk. NT Parks enforces a 36 degree rule across Watarrka National Park: if the forecast for the day is 36 degrees or higher, walkers must start the Rim Walk before 9am. Rangers do close the trailhead. Plan around it rather than turning up and hoping.

If you’re not coping on the way up, turn around. The climb is the only point on the loop where going back is easy. Once you’re on the rim, you’re committed to the full 6km.

Practical tips

Water. There is none on the trail. The car park is the last tap. Carry at least three litres per person in warm months, two in winter.
Footwear. Closed shoes with grip. The sandstone is smooth in places and thongs are a bad idea.
Timing. Start at first light. You’ll walk the climb in shade and finish before the heat builds.
Weather to avoid. Rain makes the rock genuinely slippery, and the exposed rim is a poor place to be in a storm.
Also bring: hat, sunscreen, snacks, a fly net between August and November.

Worth the stairs

If you can do the climb, do it. Three hours on that rim, with the canyon dropping away beside you and the desert running flat to the horizon, is not something you get from a lookout car park.

If you’d rather not work out the timing, the heat rules and the water logistics yourself, you can walk it as part of a guided Kings Canyon tour with us. Our multi-day Uluru and Kings Canyon trips include the Rim Walk with a guide who sets the pace and starts the group early.

Frequently Asked Questions

Roughly 500 stone steps at the start of the walk. There’s a second, much shorter set of stairs down into the Garden of Eden and back out, around 100 each way.

It depends on the severity. The marked path stays back from the edge for most of the loop, but there are lookout points where you’re standing on top of a sheer wall with nothing between you and the drop. If heights make you freeze, the Kings Creek Walk on the canyon floor is a better choice.

Physically, an active 10 year old will manage the stairs. The concern is the unfenced edges, which require kids to stay on the path for three hours straight. Most families with younger children do the Kings Creek Walk instead.

Turn around and walk back down. The climb is the only section where retreating is straightforward. After that the loop is one-way and you’re committed to the full 6km.

Yes, considerably. The Uluru Base Walk is about 10km but almost entirely flat, so it’s a question of endurance. The Rim Walk is shorter but has real elevation, uneven rock and heat exposure.

First light. Rangers require a pre-9am start whenever the forecast hits 36 degrees, and even on cooler days an early start means you climb in shade and finish before the afternoon heat.

Not along most of it. Some formal lookouts have railings or platforms, but long stretches of the rim are open rock. Stay on the marked path.
