Tunnel View Lookout

Overview

Tucked above Glenbrook Gorge, Tunnel View Lookout trades crowds for big horizons. You get sweeping views across the gorge toward Glenbrook and even out to basalt-capped peaks like Mount Banks and Mount Tomah. The lookout is unfenced and natural, so it feels wild—part of the appeal—and the namesake view picks out two historic train tunnels (built in 1911) across the valley.

What You’ll See

• Glenbrook Creek Gorge and layered Blue Mountains ridgelines
• The pair of early 20th‑century railway tunnels across the valley
• Seasonal wildflowers (notably in spring and early summer)
• Birdlife—flocks of honeyeaters, red wattlebirds and friarbirds are noted in cooler months

Getting There

Drive into the park via Glenbrook (Bruce Road entrance). Follow signs toward Mount Portal/Tunnel View; parking is near the trackhead on Mount Portal Road. From the car park, it’s roughly a 200 m bush path to the lookout. The last stretch of road is unsealed and can be corrugated with some steep, blind hairpins—take it slow. Park entry fees apply ($8 per vehicle per day).

Amenities (or lack of them)

There are no toilets, water, bins, or shelter at the lookout or trackhead. Toilets and drinking water are available back at the Glenbrook Information Centre near the park entrance carpark. No dogs (except certified assistance animals).

Best Times to Visit

Sunrise gives the softest light and the calmest feel; late afternoon adds warm color on the sandstone. It’s generally quieter than the headline Blue Mountains lookouts, so even weekends can feel peaceful. Shade is limited, and midday glare can flatten photos—time your visit for golden hours if you can. Check NPWS local alerts before you go for any access or track updates.

Wildlife & Flora

Spring and early summer bring a bloom of wildflowers—woody pears and flannel flowers are standouts. Birdwatchers do well here: watch for seasonal movement of honeyeaters and friarbirds, and keep an ear out for noisy flocks sweeping the valley.

Safety Notes

The lookout is unfenced with sheer drops. Keep children close and mind your footing on the rock near the edge. The short track is easy but can be rough in places. Weather changes quickly along the cliff tops; bring layers, sun protection, and adequate water.

Make a Day of It

Pair Tunnel View with nearby Mount Portal Lookout, Nepean Lookout, or a dip at Jellybean Pool for an easy, high‑reward Glenbrook day.
