Glenbrook Lagoon

Glenbrook Lagoon, in the lower Blue Mountains, is a rare upland wetland within the Hawkesbury-Nepean system, and provides habitat for flora and fauna species that are otherwise unusual in the area.


The lagoon was described during the historical crossing of the Blue Mountains by Blaxland, Wentworth and Lawson. In the late 1860’s the lagoon was resumed from the lands of Barnett Levy by the railways, and the storage capacity increased with the construction of a low dam (see road photo below) to provide water during the construction of the railway across the Blue Mountains. During the 1870’s water from the lagoon was used for the mountains (steam) trains.

The lagoon is about 25 minutes walk from Glenbrook and Blaxland stations. There is a walking track around the lagoon, with parking off Glenbrook Drive near Olivet Street.

It is a further 2Km walk to Lennox bridge (above right), via Kodala Lane which connects Glenbrook Road to Kedron Steet. The photo above (left) shows the rough trail from the end of High Street to Lennox bridge on Mitchell’s Pass. The bridge built by David Lennox from sandstone quarried nearby, is the oldest stone arch bridge on the mainland, completed in 1833. 

There is a Lennox bridge both in the the Blue Mountains and also in Parramatta, as Joan Elizabeth pointed out in a comment to my Parramatta post.

A small shopping centre with restaurants, take away shops and a hotel is located near the lagoon at Kidman Street, off the Great Western highway.  Blue Mountains buses (route 690) is the local bus service.

Bicentennial Park

    Badu Mangrove Board-walk and Coastal Saltmarsh

Sydney's Bicentennial Park is just west of Concord West station (about 15Kms from Central station) and is adjacent to Sydney Olympic Park. The Badu Mangrove boardwalk enables people to walk through the largest remaining mangrove ecosystem along the Parramatta River.

A coastal saltmarsh is a salt-tolerant plant community that lives between high and low tide, often behind mangroves.

On our visit, the air had a smoky haze from hazard reduction burning in the Blue Mountains the previous day.

The parklands contain diverse habitats for many plants and animals that are significant locally, nationally and internationally. These include rare saltmarsh communities, breeding populations of insectivorous bats and endangered Green and Gold Bell frogs. Species of migratory birds protected under international treaties also often roost and feed in saltmarsh during their stay in Australia.

   The Brickpit Ring Walk

The Ring Walk is within Sydney Olympic Park,  was opened in 2006. It is an elevated circular walkway which allows visitors access to view the former brickpit area without disturbing the habitat of the endangered Green and Golden Bell frogs.

The Ring Walk, is 550 metres in circumference and is 18.5 metres above the floor of the Brickpit.
The original audio has packed it in, but the informative panels around the side are in good condition. They give a history and geology of  the Brickpit and information on the frogs.

My thanks to Jean B. for leading us on this interesting walk
