Purnululu National Park: The Bungle Bungles

Purnululu National Park is one of Australia’s most extraordinary geological landmarks. Located deep in the remote wilderness of Western Australia’s Kimberley region, this vast expanse of spinifex-covered plains and deep gorges is home to the world-famous Bungle Bungle Range.

For over 20 million years, the Bungle Bungles were unknown to the outside world, familiar only to the local Gija and Jaru Aboriginal people and a small number of local stockmen who kept quiet about the difficult terrain. It wasn’t until 1983, when a documentary film crew captured aerial footage of the strange, striped domes, that they became known to the broader public.

These massive, beehive-shaped sandstone towers — rising 300 meters out of the flat plains — look like the ruins of an ancient city or a scene from a science fiction film. Today, Purnululu is a protected UNESCO World Heritage Site and a top destination for adventurous travelers willing to navigate the corrugated dirt tracks of the Kimberley.

Geological History: The Striped Beehives

The geology of Purnululu is unlike anything else on Earth. The story of the Bungle Bungle Range began roughly 360 million years ago, when a massive river system deposited sand and gravel into a basin. Over millions of years, this sediment compressed into soft sandstone.

About 20 million years ago, tectonic movements uplifted this sandstone plateau. Then the intense tropical monsoons of the Kimberley went to work, eroding the soft rock along vertical fault lines and slicing the plateau into a chaotic maze of steep-sided domes and deep narrow gorges.

The Mystery of the Stripes

The most distinctive feature of the Bungle Bungles is the horizontal tiger-striping of vibrant orange and dark grey/black bands across the domes.

• The Black Stripes: The dark bands indicate layers of porous sandstone that hold moisture. In these damp bands, cyanobacteria (blue-green algae) flourish. The black color is the dark pigmentation of millions of these microscopic organisms.
• The Orange Stripes: The orange bands indicate layers with lower porosity. Cyanobacteria cannot survive here. Instead, iron compounds in these layers are exposed to sun and oxygen. The brilliant orange color is the rock oxidizing — quite literally, rusting.

Because the sandstone lacks a protective crust, the only thing holding the domes together is the thin “skin” of cyanobacteria and iron oxide. For this reason, climbing on the domes is strictly forbidden; even walking on them breaks the crust, causing rapid, irreversible erosion.

Wildlife and Biodiversity: Life in the Spinifex

At first glance, the searing heat and dry rocky terrain appear hostile to life. However, the park supports a surprisingly diverse array of flora and fauna, particularly in the deep shaded gorges where permanent water persists through the dry season.

The Animals of the Kimberley

• Mammals: The park is home to agile wallabies and short-eared rock-wallabies, which can often be seen bounding up near-vertical gorge walls at dawn and dusk. Echidnas are common but rarely seen due to their nocturnal habits.
• Reptiles: Purnululu holds over 80 reptile species, including large Gould’s goannas (monitor lizards), the patterned centralian blue-tongued skink, and various geckos that hunt on rock walls at night.
• Birdlife: Huge flocks of little corellas and colorful rainbow bee-eaters fill the air, while the spinifex pigeon (which camouflages perfectly against red rocks) scurries across the ground. In the deep gorges, look for the white-quilled rock pigeon.

Flora

The plains surrounding the domes are dominated by spinifex grass and low acacia shrubs. Walking deep into the gorges, the microclimate shifts dramatically — sheltered canyons support tall Livistona fan palms and native fig trees whose roots grip the sheer rock walls.

Top Hikes and Attractions

The park divides into two distinct areas: the southern end (striped domes) and the northern end (deep conglomerate gorges).

1. The Domes Walk and Cathedral Gorge (South)

• The Domes Walk: A short, flat 1-kilometer loop that weaves between the bases of the massive domes. Standing directly beneath them is the only way to fully appreciate their scale.
• Cathedral Gorge: The trail continues into a cavernous, bowl-shaped natural amphitheater. In the wet season, a waterfall drops from the roof into a permanent pool at the center. In the dry season, the acoustics inside the gorge are remarkable — visitors often whisper and listen to their voices reverberate off the overhanging walls.

2. Piccaninny Creek Lookout (South)

For fit and well-prepared hikers, the Piccaninny Creek trail offers a challenging multi-day unmarked hike into the heart of the massif. For day visitors, a shorter 2.8 km walk leads to a lookout with views down the dry rocky riverbed weaving between the domes.

3. Echidna Chasm (North)

In the northern part of the park, smooth striped sandstone gives way to rough boulder-studded conglomerate rock.

• The Hike: Echidna Chasm is a slot canyon. The hike takes you deep into a crack in the earth. As you progress, sheer walls rise 200 meters (650 feet) straight up while the path narrows to shoulder-width.
• The Light Show: The best time to visit is around midday. The sun is positioned overhead and shoots a shaft of light directly down into the dark chasm. The conglomerate walls light up in fiery gold and orange against the cold dark shadows — one of the park’s most photographed sights.

4. Scenic Helicopter Flights

The Bungle Bungle Range covers 45,000 hectares and the domes are densely packed. Walking among them shows only a fraction of the landscape. A helicopter flight from the park’s Bellburn airstrip (or fixed-wing flight from Kununurra) gives the only perspective that reveals the full scale and geometry of the range. Most visitors who have done both regard the flight as the more memorable experience.

Seasonal Guide

Purnululu has two extreme seasons: the Wet and the Dry.

• The Dry Season (May – August): The best time to visit. Days are clear, sunny, and warm (25–30°C / 77–86°F), with low humidity. Nights can drop near 0°C (32°F). All trails are accessible.
• The “Build-Up” (September – October): Heat builds rapidly. Daytime temperatures regularly exceed 40°C (104°F) with rising humidity. All hiking should be completed before 10:00 AM to avoid dangerous heat exposure.
• The Wet Season (November – April): The park is completely closed. Torrential monsoon rains wash out the access roads. The only way to see the park during this period is via scenic flight from Kununurra.

Budget and Packing Tips

Purnululu is remote wilderness. Complete self-sufficiency is required.

• The Access Road (Spring Creek Track): The turnoff is on the Great Northern Highway. From the highway, you must drive 53 kilometers of unsealed Spring Creek Track — heavily corrugated, with multiple creek crossings and steep rocky jump-ups. Allow 2 to 3 hours. This track is 4WD only. Caravans are banned, but there is a secure storage park at the highway turnoff.
• Accommodation:
  • Camping: The DBCA operates two public campgrounds: Kurrajong (North) and Walardi (South). Basic bush camps with drop toilets and non-potable bore water. No showers or power. Book online months in advance.
  • Glamping: Two private wilderness lodges offer luxury safari tents with beds, hot showers, and catered meals at significant cost.
• Water: There is no safe drinking water anywhere in the park. Bring all your own — a minimum of 4 to 5 liters per person per day for drinking and hiking.
• Fuel and Food: No shops, cafes, or fuel stations exist inside the park. Fill tanks and stock supplies in Kununurra or Halls Creek before driving in.
• Fly Nets: During warmer months, outback flies are relentless. A cheap head-net is highly practical.

Frequently Asked Questions

Can I drive in with an AWD or 2WD vehicle?

No. A high-clearance, low-range 4WD vehicle is mandatory. The Spring Creek track features steep rocky sections and soft sand river crossings. A 2WD or low-clearance AWD will almost certainly get stuck, causing severe undercarriage damage and a costly tow. Without a 4WD, book a guided bus tour or fly-in tour from Kununurra.

Are there crocodiles in the waterholes?

Unlike Kakadu or coastal areas of the Kimberley, Purnululu is generally safe from saltwater crocodiles. The park is located far inland, and the gorge waterholes are mostly seasonal (drying up in the dry season), so they cannot support permanent crocodile populations.

How many days should I plan for?

A minimum of two nights allows one full day for the southern domes (Cathedral Gorge area) and one full day for the northern gorges (Echidna Chasm), plus time for a scenic flight. Visitors who rush through in a single day consistently report feeling they missed the park.

Is there cell phone reception?

No. Once you turn off the Great Northern Highway, you lose all mobile coverage. There is no Wi-Fi at public campgrounds or the visitor center. Carrying a satellite communicator or Personal Locator Beacon (PLB) is strongly recommended for independent travelers.

Can I fly a drone over the domes?

No. Recreational drones are prohibited within Purnululu National Park to protect the cultural significance of the area for the Traditional Owners, preserve the wilderness experience, and ensure safety for the low-flying scenic helicopters operating over the range.
