It is located 63 kilometres (39 mi) west of the Sydney central business district, in the local government area of the City of Blue Mountains.

It plays host to trendy cafes and boutiques, while offering various tourist attractions, including weekend markets, recreational opportunities and native flora and fauna.

The town takes its name from Glenbrook Creek, which is on the southern side of the village and must be crossed to enter the Blue Mountains National Park.

[2] In 1815, William Cox constructed the first road over the Blue Mountains with a gang of convicts and the Glenbrook area became an important stopping point after a storeroom was built near the lagoon.

This was later widened to carry the old Great Western Highway, and it is now part of a walking trail on the old railway/highway alignment, including a memorial to the engineer in charge of the construction of the Blue Mountains line and many other early railways, John Whitton.

As a result of the new line, the Old Glenbrook station was relocated from next to the Great Western Highway to its current location next to the village of Glenbroook at the end of Ross Street, and was officially opened 11 May 1913.

[4] The abandoned 1892 Glenbrook Tunnel has been used to store mustard gas during World War II, and grow mushrooms in recent times.

Since 2005, the suburb has been the home of The Australian Gnome Convention organised by the Rotary Club of Lower Blue Mountains and held on Australia Day each year.

[10][11] On the trail to the caves, along the banks of Camp Fire Creek, there are also aboriginal axe grinding grooves on the Sydney Sandstone.

[13][14] Additionally, Glenbrook hosts many natural pools and swimming holes, that can be accessed by walking tracks from the town centre, by a few kilometres.

Netball is currently the largest participation sport in the Blue Mountains and all matches are played at the Lapstone complex.
