Jarrangbarnmi (Koolpin Gorge)

Overview

Jarrangbarnmi, better known as Koolpin Gorge, is Kakadu’s wild card: a gated, permit-only gorge with sheer red cliffs, clear plunge pools and a true sense of wilderness. It’s remote, uncrowded, and feels like a secret—because it kind of is.

Why it’s special

Access is capped (about 40 people at a time), so you won’t be sharing the pools with a busload of people. The Gorge’s mouth delivers classic Kakadu scenery—cascades and deep rock pools—with the option to keep exploring further up the gorge for a raw, adventurous feel.

Access and permits

You must secure a permit in advance (allow at least 7 days for processing), then collect a key to unlock the gate. Once inside, you’re on a rough, high-clearance 4WD track with creek crossings that ends at the small Jarrangbarnmi camping area—right where the walk begins.

What you’ll do and see

From the campground, a short walk reaches plunge pools and waterfalls at the start of the gorge. You can continue up to 2 km into the gorge without a separate bushwalking permit. Expect rugged sandstone, shaded pockets of monsoon greenery, and multiple pools to hop between when conditions are declared safe.

Wildlife

This fragile area shelters rare species—standouts include the hooded parrot in the surrounding woodland. Around the pools, keep an eye out for water monitors, birds, and other Top End regulars.

Camping and facilities

The campground is basic bush camping: a pit toilet and a small parking area, but no showers, no potable water, no store, and no Wi‑Fi. Bring everything you need, including all drinking water.

Safety notes (especially crocodiles)

Crocodile management is active here and pools can close for safety or cultural reasons. Always follow current ranger advice and posted signs before swimming; some lower pools may be off-limits, while upper pools are the usual go-to when open.

Best time to visit

Dry season (roughly May–October) offers the most reliable access and pool clarity. Thanks to the strict cap, it’s never truly crowded, but permits book out in peak dry season—apply early.
