The season is just about to start.

Sydney might be a concrete jungle, but it’s definitely not short on natural beauty. From coastal hikes to UNESCO-listed national parks, nature is never far away. But hidden on the city’s northernmost fringes is a reserve most locals have never heard of – a protected patch of bushland that opens to the public for just six weeks a year.

Where is it?

Muogamarra Nature Reserve is only a 45-minute drive from Sydney’s CBD, situated between the small suburb of Cowan and the iconic Hawkesbury River, which just got a brand-new walk. Its sheltered location, paired with a varied landscape and temperate climate, creates the perfect conditions for a flourishing environment.

The natural sanctuary is a haven for Australian wildlife, with 14 native mammals, 16 reptile species and around 140 native birds recorded across its 2,274 hectares. Visitors are encouraged to keep their eyes peeled for echidnas, brushtail possums, swamp wallabies, kookaburras and lyrebirds, among others.

Muogamarra Nature Reserve is also home to a thriving wildflower population, making spring the ideal time to visit. Native flowers are especially abundant, including dazzling waratahs, delicate eriostemons, angophoras, boronias, Gymea lilies and even native wild orchids.

Why the six-week limit?

The National Parks and Wildlife Act 1974 was designed to conserve NSW’s diverse natural ecosystems, officially listed as ‘protected areas of NSW’. The network of nature reserves, including Muogamarra, is protected by the state government and managed by the NSW National Parks and Wildlife Service .

While many protected areas of NSW can be accessed year-round, Muogamarra Nature Reserve is only open to the public for six weeks of the year. This is due to ongoing conservation efforts, as well as a range of scientific and educational purposes. The fragile environment has remained relatively undisturbed for centuries, creating a remarkable landscape of cultural, botanical and geological significance.

Located on Muogamarra Country, it is also home to a number of important cultural sites for the Traditional Owners of the land, the Dharug and Guringai Peoples. Rock art, engravings, shell middens and earthenware offer insight into thousands of years of First Nations culture, a heritage that must be protected and preserved.

Add in the diverse array of flora and fauna that depend on this place, and it’s easy to see why it stays closed for most of the year. But for six weeks each spring, the gates open – offering visitors a rare chance to discover its natural beauty.

Planning your visit

There are multiple ways to experience Muogamarra Nature Reserve. Guided hikes are run during the six-week open window, all offering a different perspective. Beginners are encouraged to join the three-kilometre Muogamarra Highlights Walk or the 3.5-kilometre Muogamarra: Bird Gully Guided Walk.

There’s also the Muogamarra: Lloyd Trig and Deerubbin Guided Walk, a 6.6-kilometre loop that provides uninterrupted views of the Hawkesbury River. If you’re up for a challenge, the 10-kilometre, full-day Muogamarra: Peats Bight Guided Walk is for you. Or tackle one of many gorgeous self-guided trails at your own pace. Hungry for more? Head to nearby Ku-ring-gai Chase National Park, where you can explore bushwalks that lead to secret swimming spots.

Unfortunately, visitation in 2025 (from 9 August to 15 September) is completely booked out. But don’t despair – there’s always next year! Get in early to secure your spot now by emailing the NSW National Parks and Wildlife Service directly or calling 13000 PARKS.

No time to hibernate: experience the best of winter in NSW

    Kate BettesBy Kate Bettes
    Continue
    Whales breaching, fires crackling and slow-cooked feasts that make the cold so cosy, one might wish it lasted longer. Winter is no time to stay at home in NSW.

    When the mercury drops, winter in NSW comes into its own. Beaches are quieter, the air is crisper and hearty food tastes even better when there’s ice on the windows.

    Winter here isn’t for hiding away. It’s for long walks, deep baths, deeper reds and the kind of fireside lounging that feels simultaneously indulgent and entirely deserved after a day of exploring. From whale-watching up north to moodily lit bushwalks and pastry pilgrimages, we’ve mapped out your new favourite season.

    From coastal walks to tasty delights, winter in NSW is a time to get out and about.

    The Tweed

    In winter, the NSW north coast has a front-row seat to one of nature’s greatest migrations. From May to November, humpbacks cruise past the Tweed coast between Antarctica and the Great Barrier Reef. Spot them from the Cabarita Beach headland or get up closer with a boat cruise.

    Inland, find the Tweed Regional Gallery & Margaret Olley Art Centre , which is home to a rotating cast of big-name exhibitions (including Monet).

    Later, grab a table at Bistro Livi , where the modern Spanish menu features whipped salt cod on toast and spanner crab with curry butter and spelt flatbread. Stick around to poke through the artist studios and indie boutiques of M|Arts Precinct .

    The next day, jump aboard the Indigenous Lunch Cruise with Tweed Escapes. You’ll cruise upriver listening to yarns from local Indigenous guides, stop at the Minjungbal Aboriginal Cultural Museum and tuck into lemon myrtle-crusted snapper.

    Next, drive out to Farm & Co to pull apart some juicy smoked lamb shoulder with green olive tapenade while gazing out over the macadamia fields and avocado groves of this working farm.

    End the day at Mantra on Salt Beach where you’ll enjoy beach access, a heated rock spa and a lagoon pool.

    Blue Mountains

    The cold season is hands down the best time to visit the Blue Mountains. Temperatures are perfect – sunny enough for hikes, and crisp enough at night for snuggling up.

    For a trip that equally soothes and stirs, start with a meditative meander through the national park’s eucalypts and Australian wildflowers. Brave the steepest passenger railway in the world, Scenic Railway , then hop the Skyway aerial cable car for unrivalled Three Sisters views.

    Thaw out at the Japanese Bath House in South Bowenfels. Soak in steamy outdoor onsens filled with natural mineral water and mountain views, wander the rose and zen gardens, or sip hot drinks in the tea house.

    Afterwards, head to Ates in Blackheath, where everything revolves around a 150-year-old ironbark-fuelled oven – like the wood-roasted duck with nectarines and Szechuan spice. Or visit Tempus Katoomba , which leans experimental and sustainable, serving up dishes like braised fennel with cumin, spiced yogurt and Aleppo pepper.

    Rug up and head into the night with Blue Mountains Stargazing . Sessions are guided by astrophysicists, helping you understand what you’re looking at as you look into deep space.

    Wrap it all up at Fairmont Resort Blue Mountains – MGallery Collection . There’s a whiskey bar in the basement (and crackling fires that make a dram taste even better), indoor and outdoor pools and a day spa. Kids will love the mirror maze and ice rink, too.

    Southern Highlands

    Good food and wine by the fire, experienced between sifting through second-hand treasures, is a winter vibe in Bowral.

    Start with a lap around Dirty Janes , an antique and vintage market. Recover from your shopping frenzy at Bendooley Book Barn , where floor-to-ceiling shelves and a roaring fire set the tone for an afternoon of red wine or hot coffee.

    When it’s time to eat, head to Hickory’s Restaurant & Bar , Peppers Craigieburn Bowral’s onsite restaurant. Try the crispy pork belly with Granny Smith crisps and apple gel, or ocean trout with wakame, lemon gel and pickled radish.

    Another option, Onesta Cucina , does Italian with flair. For something more casual (with cocktails), Flour Bar swings between brunch and dinner, with an onsite bakery, over 400 wines and a hidden deli in the old bank vault.

    Later, clamber Mt Gibraltar , where trails wind through eucalypt forest to views over Bowral and Mittagong.

    Stay at Peppers Craigieburn Bowral , a century-old estate with open fires, elegant lounges and a nine-hole golf course.

    Penrith

    Shake off winter inertia with an adrenaline boost out in Penrith. Kick things off with a kayak paddle on the Nepean River with Horizon Line, or head to Cables Wake Park , where cold-weather wetsuits take the edge off a wipeout.

    For something a bit more cruisy, opt for the Nepean Belle Paddlewheeler for slow-floating views and a hot cuppa.

    Refuel at Marcel Bar & Bistro , where reimagined European comfort food – like seafood risotto in bisque with little neck clams and Moreton Bay bugs – is king. Then check in at the Pullman Sydney Penrith , the area’s first international five-star hotel, to enjoy your well-earned rest.
