Blue Mountains National Park

One of eight reserves in a World Heritage property of over a million hectares, and the one nearly every visitor actually enters. What it protects, what it costs, and why a sandstone plateau ended up on the same list as the Great Barrier Reef. The practical side of a visit is on the visiting page; the best Blue Mountains day tour are compared separately.

What the Greater Blue Mountains Area protects

The property was inscribed on the World Heritage List in 2000 and covers over one million hectares, spread across eight adjacent conservation reserves. NSW Environment and Heritage records the listing as recognition of its natural values, and the National Parks and Wildlife Service summarises the case as outstanding geology, biodiversity and Aboriginal significance.

It is a plateau rather than a mountain range in the alpine sense. Nothing here is especially high; what makes it remarkable is how deeply the sandstone has been cut, and how much intact bushland sits between the cuts.

The eight reserves, and where the park sits among them

Blue Mountains National Park itself is divided by the National Parks and Wildlife Service into six areas: Katoomba, Blackheath, Glenbrook, the Lower Grose Valley, Mount Wilson and the Southern Blue Mountains. A day tour from Sydney sees the first three.

Why 96 eucalypt species matter

The listing rests substantially on the eucalypts. NSW Environment and Heritage records 96 species within the property, which is 13 per cent of all eucalypt species on earth, concentrated in a single protected area. That density is the evolutionary story the inscription cites: a landscape where the genus diversified and where the record of it is still standing.

It is also why the range looks the way it does. Oil evaporating from those leaves scatters short-wavelength light, and the haze it leaves over the ridgelines reads as blue at a distance.

The Wollemi pine

Among the rare and endangered plants in the property is the Wollemi pine, Wollemia nobilis, recorded by NSW Environment and Heritage as occurring here. Its wild location is not published, and it is not somewhere a visitor goes. It is, however, the single clearest answer to why a plateau ninety minutes from a capital city carries a World Heritage listing.

Sandstone, swamps and 245 million years

The National Parks and Wildlife Service dates the coal and shale beds under the Katoomba escarpment to between 245 and 290 million years ago, when the area held vast swamps and deltas. Millions of years of volcanic uplift and erosion since then carved out the Jamison Valley and the Three Sisters standing off its northern wall.

What a visitor sees at a lookout is the cut, not the peak: a plateau surface at around a thousand metres, and a valley floor several hundred metres below it.

Country, and the six nations

The Katoomba area lies within the Country of the Dharug, Gundungurra, Wiradjuri, Darkinjung, Wanaruah and Dharawal People, as the National Parks and Wildlife Service records it. The Three Sisters is a declared Aboriginal Place. More than one version of the story attached to the formation is told, which is worth knowing before a guide tells you one of them as though it were the only one.

Fees, and the one place they apply

There is no admission charge for Blue Mountains National Park. The National Parks and Wildlife Service applies a vehicle fee of $8 per vehicle per day at attractions in the Glenbrook area only, and the entry station there operates on weekends, public holidays and school holidays. Everywhere else — Katoomba, Blackheath, Wentworth Falls, Mount Victoria — there is no gate and nothing to pay.

When it is open, and when it closes

The park is always open, though parts of it close overnight, and it may close in poor weather or high fire danger. That last clause does real work in an Australian summer, and it is why the alerts page is worth a look the night before rather than the morning of. Guided departures run in rain and fog rather than cancelling; what they cannot do is open a road that has been shut.
