A historic Sydney swim site just reopened in time for summer

Summer has only just begun and Sydney’s already scored a new spot to cool off. The sandy riverside stretch is offering locals a quiet escape from the heat and hints towards a city slowly reclaiming its waterways.

Where is Sydney’s new beach?

Nestled along the Parramatta River roughly 15 kilometres from Sydney’s CBD, the waterfront suburb of Gladesville has gained a new swimming spot just in time for summer. Although new may not be the most accurate way to describe it.

Originally opened to the public back in the 1860s, Bedlam Bay has long been a treasured outdoor space for the local community. But the bathing site was demolished in 1956 due to the development of a sports oval and increased water pollution. Now, after almost 70 years, swimmers are being welcomed back.

Hunters Hill mayor Zac Miles says reactivating the site provides a valuable community asset this summer. “This project highlights our ongoing commitment to enhancing community recreation around our natural waterways. It’s great to reactivate this cherished place once again for our community and visitors alike to enjoy."

Nestled at the bottom of Parramatta River Regional Park, the swimming spot looks out towards bobbing moored boats and is surrounded by greenery. It’s a low traffic area with plenty of peaceful pockets to enjoy the sun – minus the crashing waves, crowded shores and often long-winded drives to other popular beaches in Sydney.

Is it safe to swim at Bedlam Bay?

In recent years, local councils and the NSW government have been committed to improving the water quality of the Parramatta River. Working with Sydney Water and the Parramatta River Catchment Group , over $560,000 worth of funding has been invested into making Bedlam Bay suitable for swimmers again.

Upon opening, the site features a secure shark net to keep visitors safe, as well as on-site lifebuoys and a boat jetty. It adds to a growing line-up of seven revitalised swimming spots along the waterway, including the establishment of Putney Beach back in January.

Thanks to programs like RiverWatch™, water quality at the site has been continuously monitored since 2020 to ensure it is safe for aquatic activities.

The Sydney Water initiative assesses microbial contaminants such as algae, enterococci and chlorophyll-a in water samples, as well as temperature, turbidity (the amount of material suspended in the water) and conductivity (an indicator of salts in the water).

Even once a site is marked safe, levels are continuously monitored during its ongoing operation. Routine sampling occurs every four to six days, as well as five days of consecutive targeted sampling at sites that have received heavy rainfall.

“Our RiverWatch™ recreational water quality monitoring program was specifically established to support the opening of new swim sites in waterways," says Leanne Niblock, waterway coordination manager of Sydney Water.

“Sydney Water has also made a significant investment in upgrading the wastewater network in the upper and mid Parramatta River catchments to reduce the impact of wet weather overflows, directly supporting the swimming outcome in the Parramatta River."

There are also plenty of public transport options . Sydney’s F3 ferry service from Circular Quay will take you to Huntleys Point Wharf, two kilometres away. This route also stops at all major ferry terminals along the Parramatta River. The 501, 507 and 536 bus routes all stop at Gladesville Hospital, too.

Like many of Australia’s natural swimming holes, locals heading to Bedlam Bay can dive in with confidence knowing that they’ll be swimming safely this summer. Stay up to date with water quality alerts via Urban Plunge by Sydney Water or the Parramatta River Catchment Group’s interactive map .

    Kassia Byrnes Kassia Byrnes
    Continue
    Thredbo in summer is a nature lover’s dream of show-stopping alpine beauty, cool mountain air and magical moonlit adventure.

    For many of us, Thredbo calls to mind shimmering slopes and snow-dusted gums, but come summer, this Alpine resort transforms into a playground of an entirely different kind. A cool mountain retreat despite the season, Thredbo summer hikes are astonishingly beautiful, criss-crossing over dramatic peaks, pristine glacial lakes and abundant flora and fauna.

    From approachable tracks for novice walkers to more challenging hikes across the Main Range and even journeys under moonlight, Thredbo puts on an unforgettable show of natural splendour all summer. Lace up your walking boots and take the chairlift from Thredbo village to embark on a self-guided exploration or a tour of the Snowy Mountains’ most compelling landscapes.

    These eight unforgettable hiking experiences are only available in summer and offer an alpine adventure like you’ve never experienced before.

    1. Full Moon Hike to Mt Kosciuszko

    There’s something almost mystical about hiking by the light of a full moon. This guided experience begins with a 15-minute chairlift ride, where you’ll admire the Thredbo Valley below, bathed in the fading sun.

    Once at the top, you’ll pass rivers, alpine lakes and spot nocturnal wildlife on your way to the Kosciuszko Lookout and Lake Cootapatamba. By the time you reach the summit, sunset is well underway as you watch day give way to night and the alpine landscape magically illuminated by the lunar glow. Enjoy a hot chocolate here before following the path back to Eagles Nest, brightened by the night sky.

    This 13-kilometre hike will take place on 3 January, 2 February, and 2 April in 2026.

    2. Super Full Moon Hike

    Take in the might of a super full moon.

    The only thing that could level up the celestial beauty of a full moon hike would be a super full moon hike . Following the same route, you’ll meet the moon when it is largest and closest to Earth by ascending to the summit of Mount Kosciuszko at an elevation of 2228 metres. From such a height, it almost feels as though you could reach out and touch its glowing surface.

    Given the rarity and splendour of the super full moon, limited spots fill up fast for this awe-inspiring hike, so be sure to book the 5 December in advance.

    3. Lunar Eclipse Hike

    What could be more extraordinary than witnessing a lunar eclipse from Australia’s highest peak? Whether you’re a keen astronomer or simply revel in nature’s beauty, this guided 13-kilometre hike will place you on top of Mount Kosciuszko just as Earth passes between the sun and moon, throwing shade over the lunar surface before transforming it with a deep-red hue.

    It’s an epic place to witness one of our galaxy’s most spectacular and rare light shows. Apart from the dazzling celestial display, you’ll also enjoy walking through the moon-bathed landscape, an evening chairlift ride, and a hot chocolate at the summit.

    Book now for 3 March.

    4. New Moon Hike

    Catch the changing skies of a new moon.

    A stargazer’s delight, the darkness of a new moon gives the Milky Way full permission to dazzle with its shimmering display. Both astronomers and photographers will relish this opportunity to observe and capture the starry skyscape from the lofty height of Australia’s highest peak, Mount Kosciuszko. Departing Thredbo Village at dusk and leaving its twinkling lights far below, you’ll arrive at the summit in time to see the sun slip away and the stars appear.

    Catch this hike during the new moon lunar phase on 20 December, 19 January, 17 February, 19 March or 17 April.

    6. Merritts Nature Track

    On warm summer days, venturing into the cooler air of Thredbo’s alpine tracks offers relief from the heat. Particularly if you set course for the four-kilometre Merritts Nature Track , where there are opportunities to take a refreshing dip in swimming holes along the way.

    The two-to-three-hour self-guided hike meanders through towering ancient trees (dubbed the ‘Pixie Forest’ by locals), takes in stunning mountain vistas and is soundtracked by the melody of birdsong. Stop for a picnic and discover a hidden natural infinity pool, the location of which is given away by the roar of a cascading waterfall.

    7. Mt Kosciuszko Summit Tour

    Follow a guide along Mt Kosciuszko's summit.

    While you can easily steer yourself to Australia’s most iconic peak without a guide, following an expert guide to the summit of Mount Kosciuszko will colour your experience with a deeper knowledge of the landscape and its wild inhabitants. The 13-kilometre return trail puts the alpine scenery on display with 360-degree views from the highest spot in the country.

    The walk begins at the top of the Kosciuszko Chairlift and takes around four to six hours to complete, but is gentle enough to be embarked upon by all ages.

    8. Snowies Alpine Walk Experience

The Snowies Alpine Walk can be tackled over two or three days and includes nightly accommodation in the iconic Thredbo Alpine Hotel, daily buffet breakfast, packed lunch and dinner vouchers, plus daily transfers to and from trail heads in a brand-new Defender.
