The Megalong Valley: The Blue Mountains' Other Side

Megalong Valley Blue Mountains — The Valley Under the Rock

Most visitors to the Blue Mountains spend their day on the Katoomba clifftops, looking south across the Jamison Valley. It's a spectacular view and it deserves its reputation. But the mountains have another side — quieter, more rural, and almost entirely off the standard tour itinerary.

The Megalong Valley lies below the escarpment south-west of Blackheath, enclosed on three sides by sheer sandstone cliffs. Its name comes from a Gundungurra word meaning "valley under the rock" — a description that captures the geography precisely. The cliffs above it are the same plateau visitors stand on at Cahill's Lookout and Boars Head. The valley floor, with its green paddocks, farmhouses and wandering cattle, is what you're looking down at.

Coming Down from Blackheath

The drive down into the Megalong Valley from Blackheath is part of the experience. The road winds through temperate rainforest — tree ferns, coachwood, mossy rock walls — the air noticeably cooler and damper as you lose altitude. It opens out suddenly onto the valley floor, and the change of scale is striking: after a morning of clifftop lookouts, you're now inside the landscape rather than above it.

On the way down, there are two short walks worth knowing about.

Coachwood Glen Nature Trail is an easy 600-metre loop through rainforest — mostly flat, about 15–20 minutes, and suitable for everyone. Coachwood trees are tall and distinctive, their smooth pale bark characteristic of the cool, wet gullies on the escarpment's lower slopes. It's a gentle contrast to the exposed clifftop stops earlier in the day, and one of the few places in the Blue Mountains where you can walk through temperate rainforest without a significant descent.

Mermaid Cave is a different proposition — 130 steps cut into the cliff face lead down to an undercut sandstone cave above a natural amphitheatre of tree ferns and a small waterfall. The light in here is unusual: filtered, green, almost subterranean. The cave has been used as a film location — productions including Mad Max: Beyond Thunderdome and Planet of the Apes have shot here, drawn by the same otherworldly quality. It's worth doing for those with the energy and a reasonable level of fitness.

The Valley Floor

The Megalong Valley has been farmed since the 1830s and has a character quite different from the rest of the Blue Mountains tourist trail. The Megalong Valley Tearooms have been serving Devonshire tea since 1956. There are two small wineries. The Six Foot Track — the historic 44km route to Jenolan Caves, originally blazed in 1884 — begins here.

For visitors arriving on a day tour from Sydney, the valley floor offers a genuine change of pace: unhurried, rural, surrounded by cliffs that put the scale of the escarpment into perspective from below.

Cliff Drive and the Lookouts Above

The best views of the Megalong Valley are from above — specifically from the string of lookouts along Cliff Drive on the Katoomba plateau's western edge. These lookouts face the Megalong rather than the more famous Jamison Valley, which means they're significantly quieter than Echo Point despite offering views that are equally dramatic.

Cahill's Lookout, at the far western end of Cliff Drive, is the standout. A 500-metre paved path leads to a series of platforms with a 180-degree panorama: the full breadth of the Megalong Valley to the west, the Narrow Neck Peninsula running down the middle, and the escarpment cliffs rising on all sides. Named after NSW Premier J.J. Cahill — who also commissioned the Sydney Opera House — the lookout opened in 1959 and still feels like a genuinely local secret.

Boars Head Rock

A short walk from Cahill's Lookout brings you to Boars Head — a sandstone pinnacle that juts out from the cliff face above the valley, separated from the escarpment by erosion and tilted slightly forward over the drop below.

The name dates to at least 1882. The Katoomba and Leura Illustrated Guide of 1940 described it as "the perfect presentation of the head of a great boar, the beetling snout, the slavering jaws, the curved tusks." From Cahill's Lookout the likeness is convincing. From the lookout closer to the rock, the angle shifts and it reads more like a horse or a dragon — a reminder that pareidolia depends as much on where you're standing as on what you're looking at.

The rock itself is unfenced. The drop from the cliff edge to the valley floor is around 600 metres, and the perspective here — the valley spread out below, the Narrow Neck Peninsula stretching away, the farmland at the bottom — is one of the more arresting in the mountains.

A Different Blue Mountains Day

The Megalong Valley doesn't feature on most Blue Mountains itineraries because it requires a detour and a descent. Most visitors never make it down. That's what makes it worth including — the contrast between the clifftop lookouts and the valley floor, between the exposed sandstone escarpment and the rainforest gullies, gives the day a shape that a morning at Echo Point and Scenic World alone doesn't.

On our Blue Mountains private tour, the Megalong Valley is one of the stops guests tend to mention in their reviews. Often because they hadn't expected it.
