Lower Weano Gorge, Handrail Pool

Lower Weano Gorge, Handrail Pool is a short out-and-back from the Weano day-use area: about 0.75 mile (1.2 km) return, with an official estimate of 1.5 hours. The first stretch is manageable, then steps take you down to the gorge floor and the walk turns into a Class 5 scramble through the narrows to the pool. This is one of Karijini's most memorable close-up gorge hikes, but the short distance hides a serious change in difficulty. Go all the way only if you're fit, agile, and experienced on steep, wet rock. If you'd rather keep your feet on a normal trail, turn back before the Class 5 section or take the separate, easier Oxer Lookout walk.

Published distances differ: some describe 1.2 km return, others 1.5 km. The stored line follows the direct Lower Weano approach and measures about 0.38 mile one way; the app distance uses the 1.2 km return figure.

Start at the Lower Weano trail near the information shelter in the Weano day-use area. The approach across the plateau is the easy part. Read the trailhead safety information before descending the steps to the gorge floor. Once you're down, the walls rise close on both sides and ordinary walking gives way to scrambling over rough rock. Direction signs are limited inside the gorge, so keep the route to Handrail Pool in mind and don't treat every side passage as part of the walk.

Follow the gorge downstream. The line becomes more demanding as it narrows: expect uneven boulders, slippery rock and some wading, with the amount of water changing over time. The last drop into Handrail Pool is the crux. Use both hands on the fixed handrail to climb down; if that feels beyond your comfort, stop above it. The pool is enclosed by tall red, silver and dark rock layers, and a small fall may feed it depending on water flow. For a photo that shows the scale, get low by the pool and keep both the water and the enclosing walls in frame.

The gorge cuts through banded iron formations made from iron-rich minerals and silica that settled on an ancient sea floor roughly 2.5 to 2.0 billion years ago. Later uplift raised the Hamersley Plateau, and streams cut through its resistant rock; fractures helped open the narrow gorges. Look for the alternating red and dark layers as you move downstream, then turn around and notice how the bands line up differently from the other direction.

Toilets, shaded seating and barbecues are at the day-use area, not down in the gorge. Bring your own drinking water and food. Gorge pools can be dangerously cold, especially from April through September, and hypothermia is possible; don't dive or jump. Flash floods can occur, so don't enter a gorge when rain is in the area and leave if it starts raining. Summer temperatures often top 40°C. Dogs and other pets aren't allowed in Karijini National Park.
