Knox Gorge

Overview

Knox Gorge is the park’s sleeper hit: a dramatic, red‑walled chasm with a wow‑factor lookout up top and a short, serious scramble down inside. The rocks here are ancient and beautifully layered, telling a story billions of years in the making. Views take in the junction with Wittenoom Gorge, and the light can be exquisite when it rakes across the cliffs.

Hiking options

• Lookout walk: an easy ~200 m return stroll (about 15 minutes) to the cantilevered Knox Lookout for huge vistas and context of the gorge system.
• Gorge walk: a 2 km return, Class 5 route (allow 1–3 hours). Expect a steep, shaley descent, sections of hands‑on rock scrambling, and boulder hopping along the floor. In season you’ll find small waterfalls and natural pools; the water is bracingly cold even on warm days.

The public route ends at signs/ropes where a Class 6 restricted section begins—do not continue beyond the marked endpoint unless you’re on an approved guided trip.

Safety & hazards

This is a true gorge environment: leave immediately if rain threatens because flash floods can occur. Water can be extremely cold from April to September, so limit immersion time and never dive or jump. Summer heat is fierce (often over 40°C), so carry plenty of water (plan on at least 1 liter per hour per person), wear sun protection, and pace yourself. The area intersects with Wittenoom Gorge where blue asbestos occurs—avoid disturbing dust and heed all signage. Dingoes are present in the park: don’t feed them and secure food. Glass and alcohol aren’t permitted in the gorges, and drones are restricted.

Consider carrying a personal locator beacon if you’re heading into the gorge, and wear sturdy footwear with good grip; the entry/exit is steep and loose.

Best time to visit

April–September is the sweet spot: cooler walking temps, softer light, and (in many years) flowing water. Aim for early morning or late afternoon for the lookout when the sun grazes the cliffs and colors pop. In the hot/wet season (roughly November–April), storms and extreme heat are common—check conditions before committing. Water levels can vary by season and year, so set expectations accordingly.

Logistics

Access is from the Knox Gorge Lookout car park at the end of Joffre Road, roughly an hour east of Tom Price. There are no toilets or taps here—come prepared and pack out waste. Park entry fees apply (per‑vehicle). There’s no fuel within the park; top up in Tom Price (about 80 km west) before you go.
