Kings Canyon Rim Walk: The Complete Guide to Watarrka National Park
Kings Canyon is one of those places that reveals itself slowly. From the car park, you can see the canyon walls rising in the middle distance — red sandstone cliffs perhaps 100 metres high — but the scale doesn’t fully register until you’re standing on the rim, looking down into the shaded gorge below and across to the domed sandstone plateau known as the Lost City. It is one of the most dramatic landscapes in the Australian interior, and the 6-kilometre rim walk that traces its edge is among the finest half-day hikes anywhere in the country.
Watarrka National Park, which contains Kings Canyon, sits roughly 330 kilometres southwest of Alice Springs in the Northern Territory. It’s a logical addition to any Red Centre itinerary — often visited as a day trip from Alice Springs or as a stopping point between Alice and Uluru on the Red Centre Way. The canyon is significantly less visited than Uluru or Kata Tjuta, which gives it a quieter, more exploratory quality. On a busy day at Uluru you’ll share the dawn viewing area with hundreds of people; at Kings Canyon you might share the rim walk with a dozen.
This guide covers the rim walk in detail, the alternative canyon walk below, the best time to visit, practical logistics, and what makes this particular piece of the Red Centre worth the detour.
📋 TL;DR — the quick version
- ✅ The rim walk is the main event: 6 km, 3–4 hours, returning to the car park. Moderate difficulty with one steep initial climb. The views across the canyon and the Lost City are outstanding.
- ⏰ Start before 9am in summer: The walk is fully exposed. Heat kills — the Northern Territory Parks Service closes the walk above 36°C. Start early or not at all in hot months.
- 💧 Carry more water than you think: At least 2–3 litres per person. There’s no water on the walk.
- 🌿 The Garden of Eden is the highlight: A hidden waterhole and lush vegetation at the bottom of the canyon, surrounded by towering walls. Swimming is permitted.
- 🚗 Kings Canyon Resort is the only accommodation base: 10 km from the car park. Book well ahead in peak season (May–September).
- 📅 May to September: Best conditions. Summer heat can be extreme and the walk is closed when temperatures exceed 36°C.
🥾 The rim walk: what to expect
The Kings Canyon Rim Walk begins with a heart-rate-raising choice: the first section is a steep staircase climb directly up the canyon wall, covering perhaps 100 metres of elevation in a short, direct ascent. There is no way around it — this is the start of the rim walk, and it’s the hardest part of the entire hike. It’s not technical, but it’s sustained, and in warm weather it will make you sweat. Most people stop to catch their breath halfway up. By the top of the climb, you’re already on the rim, and the views behind you — back across the desert to the car park and the distant plains — are already worth the effort.
From the top of the climb, the walk traces the southern rim of the canyon before crossing to the northern wall. The canyon itself drops away on your right — a sheer 100-metre wall of banded sandstone, shaded and cool-looking even in the heat of the day. The rock is a deep red-orange, banded in horizontal layers that reflect the ancient sand dunes from which it was formed (this area was a vast dune field more than 400 million years ago; the sandstone is compressed and cemented dune sand).
🌿 The Garden of Eden
Roughly halfway through the walk, the track descends from the rim into the canyon interior, reaching a permanent waterhole known as the Garden of Eden. The contrast with the surrounding desert is startling — cycad palms, ferns, and dense vegetation crowd the waterhole, fed by water that seeps through the porous sandstone above. The walls of the canyon rise on all sides. It’s shaded, cool, and completely enclosed — a world utterly different from the baking plateau above.
Swimming is permitted at the Garden of Eden — the water is clear, cold, and genuinely refreshing after the climb and the exposed section of the rim. This is a natural rest and swim stop for most walkers. From here, the track climbs back to the rim and continues around the northern side of the canyon, giving different views of the Lost City before returning to the car park.
🏔️ The Lost City
The “Lost City” is the name given to the plateau section of the canyon walk — a landscape of rounded, beehive-shaped sandstone domes that have been sculpted by millions of years of weathering. The domes are each a few metres high, and from the right angles they look like the buildings of a sunken, alien city — hence the name. The geological explanation (differential weathering along ancient rock fractures) doesn’t make the landscape any less surreal. This is one of the most photographed sections of the walk.

🌊 The canyon walk (alternative)
For those who want a shorter or easier option, the canyon floor walk (2.6 km return) follows the creek bed at the bottom of the canyon between the two walls, ending at the Garden of Eden waterhole. It’s flat, mostly shaded, and takes about an hour return. It gives a completely different perspective — the walls rising on either side rather than dropping away — and is a good option for children, less confident walkers, or anyone who’s done the rim walk before and wants a different experience.
🗓️ When to visit
May to September is the reliable window. Temperatures are mild to warm (15–28°C during the day), nights are cold, and the walk is always open. July and August are the peak months — the most comfortable weather but the busiest trails. April and October are shoulder months with pleasant conditions and fewer visitors.
October to April is technically possible but genuinely risky. Summer temperatures in this part of the Northern Territory routinely exceed 40°C and sometimes 45°C. The NT Parks Service enforces a weather closure of the rim walk above 36°C — you’ll arrive to find the walk closed. Even if it’s open, the exposed rim in full summer sun with no shade is not the place to be. If you’re visiting in summer, start at dawn (the walk opens at first light) and be off the rim by 9am.
🚗 Getting there and staying
Kings Canyon is 330 km from Alice Springs via the Luritja Road (mostly sealed, some gravel). The drive takes around 3.5–4 hours. Kings Canyon Resort (10 km from the car park) is the only accommodation option within the park — it has hotel rooms, glamping tents, a powered campsite, a restaurant, a bar, and a petrol station. Book early in peak season; it fills quickly.
The Red Centre Way — the loop road from Alice Springs via Kings Canyon and Uluru and back — is one of the classic Australian road trips. Combining Kings Canyon with Uluru and Kata Tjuta across 3–5 days gives you the complete Red Centre experience and makes the 330-kilometre drive worthwhile.

Kings Canyon earns its place in the Red Centre itinerary without any help from its famous neighbours. The rim walk is genuinely excellent — dramatic, varied, and offering that waterhole swimming stop that Uluru, for all its majesty, cannot match. It rewards the detour completely.
