Blue Mountains National Park, NSW
A short walk to a broad valley and two 1911 rail tunnels.
Overview
From the lookout, look across the railway cutting to the pair of tunnels built in 1911, then out toward Kurrajong and the basalt-capped Mount Banks and Mount Tomah. The gorge and wooded ridges do most of the work; the tunnels are a small but distinctive detail in the wider view. In warmer months, woody pears and white flannel flowers bloom nearby. May can bring feeding flocks of red wattlebirds, honeyeaters and noisy friarbirds. If you take a photo, keep some of the rocky foreground with the gorge so the depth reads.

Why the Rainbow Moves“A rainbow in waterfall spray depends on where you're standing. Sunlight bends as it enters each droplet, reflects inside, then bends again on the way out. Different colours leave at different angles.”

Trail guide
Tunnel View walking track is a short 0.32-mile (about 520 m) out-and-back in the Glenbrook area, ending at an unfenced lookout above a forested gorge. The mapped footpath is about 260 m one way; the total counts the same path back. Allow around 25 minutes for the walk and a look around. It is a fast scenic stop, not a longer bushwalk, and the short route here is separate from the steep approach up from Glenbrook Creek.
Start at the Emu Road access near 64 Emu Road in Glenbrook. The path is very short, but its surface and grade are not described in detail; the lookout access is rated hard, so don't assume a step-free route. The Glenbrook gates have seasonal hours: 8:30 am–7 pm from the first Sunday in October to the first Sunday in April, and 8:30 am–6 pm the rest of the year. Park entry fees apply. Dogs are not allowed except certified assistance animals.
The lookout is unfenced. Keep children well back from the edge; you can take in the full view without going to the rim.
