Cordeaux Dam – A Hidden Water‑Wonder in New South Wales
Discover the tranquil beauty of Cordeaux Dam, a lesser‑known gem perched on the slopes of Mount Keira. Perfect for day‑trippers, photographers, and anyone craving a peaceful escape from the city buzz.
Introduction
If you’ve ever driven along the winding roads that hug the Illawarra escarpment, you might have caught a glimpse of a shimmering blue lake tucked into the forested hills—Cordeaux Dam. While the iconic Sydney Harbour Bridge and the Blue Mountains dominate most travel itineraries, this serene reservoir offers a refreshing alternative for nature lovers exploring New South Wales. With its crystal‑clear waters, lush surroundings, and sweeping views of Mount Keira, Cordeaux Dam is quickly becoming a favorite spot for locals and adventurous tourists alike.
About Cordeaux Dam
Cordeaux Dam is a gravity dam built to augment the water supply for the greater Wollongong region and, indirectly, for parts of Sydney. Constructed in the early 20th century, the dam forms part of the larger Cordeaux Water Supply Scheme, which channels water from the Southern Highlands to the coastal plain.

The dam’s reservoir is surrounded by native eucalyptus forest, creating a cool micro‑climate that contrasts sharply with the warm coastal towns just a short drive away. Its historic significance lies in the engineering feats of the 1920s, when workers carved tunnels through solid rock to bring water to a rapidly growing industrial hub. Today, the dam continues to play a vital role in regional water security while offering a picturesque backdrop for outdoor recreation.

How to Get There
By Car
Cordeaux Dam is most easily accessed by car. From Sydney, take the M1 Pacific Motorway south to the Illawarra Highway (A1), then follow signs for Wollongong. After passing the city, keep an eye out for the turn‑off to Mount Keira Road (B69). The dam sits just off this road, roughly 95 km (≈1.5 hours) from Sydney’s CBD.
From Wollongong, the drive is even shorter: head north on the Princes Highway (A1), then turn left onto Mount Keira Road. In about 20 minutes you’ll arrive at the dam’s parking area.
Public Transport
While there is no direct train or bus service to the dam, you can take a train to Wollongong (NSW TrainLink) and then catch a local bus (routes 55/56) toward Mount Keira. From the bus stop, a short taxi ride or rideshare will drop you at the dam’s entrance.
Parking & Access
A modest free parking lot sits near the dam wall, offering space for cars and small campervans. The lot fills quickly on weekends during summer, so an early arrival (before 9 am) is advisable.
