This nature reserve near Sydney is open for just 6 weeks a year

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.

I’ve stayed in 21 hotels in Sydney and this is my favourite

Welcome to the first instalment of Hotel Addict, a monthly column where I check into Australia’s best hotels, exploring not just the rooms, but the stories, service and settings that make each stay unforgettable and worth adding to your wishlist.

Hotel stays have quietly become my thing. Long before I became a travel journalist, I was booking staycations just for a change of scenery. Some had charm, some had character, some had neither. Once, I even stayed in a hotel directly opposite my own apartment partly for the novelty, partly because I wanted to see my life from a different angle.

For me, hotels represent a kind of mystery I find myself wanting to know what these buildings contain. Many of them are designed with intention: lighting, materials, scent and sounds that often reflect the city they sit in. Time seems to gently pause in these spaces, which have increasingly become the destination itself for modern travellers.

It only felt fitting for the first hotel in this series to be in my home city and at the hotel that’s been at the top of my list: Capella Sydney

A sandstone heritage building and palm trees

Capella sits within an Edwardian Baroque‑style sandstone building.

An email with a hotel program from the “Culturist Team” lets me know this will be a luxurious stay. There’s a guided walk around the Botanic Gardens, a weaving workshop and a Sydney contemporary art tour the kind of addition that signals a hotel that’s tuned into the finer details, and one that’s not surprising given that Capella’s ethos centres on delivering personalised, immersive experiences. 

Capella opened in 2023 within a transformed Edwardian Baroque‑style sandstone building in Sydney’s CBD that was originally designed by renowned Scottish-Australian architect George McRae. I often walk past this building and once attended an event inside – I distinctly remember being surprised by how beautiful it was. Bar Studio, Make Architects, and stylist Simone Haag were engaged to sensitively adapt the building for contemporary luxury while honouring its past, in collaboration with Heritage NSW and the City of Sydney.

When I arrive, I’m greeted by three different staff members along the way to reception. There’s a lovely subtle scent, which I later learn combines notes of bergamot, green tea leaves, peony, freesia, vetiver and cedarwood. This hotel strikes such a beautiful balance between grandness and intimacy, with large floral bouquets, contemporary artworks, impressively high ceilings that give it an international feel and quieter nooks to unwind in. Each space is unique, but they’re all unified by a warm, textural and layered design.

Sydney has been deserving of a hotel of this calibre for quite some time, with many of the accommodations in the city looking and feeling dated.

The design strikes the perfect balance between grandness and intimacy.

I have a treatment booked at the hotel’s Auriga Spa prior to check-in. The space is ultra-luxe, moodily lit and intimate, featuring timber joinery, green walls and a sleek design that’s so perfect it almost transports me to Japan. I opt for the Replenish Beauty and LED Facial a strategic choice with a TV segment on the horizon, and a hopeful bid to look extra fresh for the camera.

The treatment begins with me sitting in the softest robe of my life, wearing slippers and sipping chamomile tea. I’m then whisked away to my private treatment room, which has its own bathroom, a large skylight and a small Japanese-style garden. The treatment is extremely relaxing and moves through cleansing, exfoliating, massaging (arm, head, neck and face) and LED Light Therapy. There’s so much attention to detail even at the end, the facialist puts my slippers back on me, while I’m still lying down.

While this treatment certainly hasn’t had a Benjamin Button effect, my sister seems to think I’m glowing, so I walk away happy, or at the very least, zen.

Auriga Spa has a sauna, steam room, ice fountain and a beautiful indoor heated swimming pool. There’s also “experiential showers” new to me, but essentially it combines water flowing from different places, changing temperatures, mood lighting, gentle sounds, and a subtle lemongrass scent.

You could easily spend the better part of a day at the spa and pool, even if you’re not a guest.

I’m escorted to my room, drunk on relaxation, but I make sure to take note of how noisy the hallways are answer: dead quiet. My room is 50 square metres, which is huge by hotel standards, but particularly for one in the CBD. It feels like a high-end apartment with floorboards, a freestanding bath and a seating/dining area. My eyes are immediately drawn to the line-up of macarons waiting for me on the dining table. 

I’m thrilled to see the mini bar armoire includes a small wine fridge stocked with Minuty Prestige Côtes de Provence, Cloudy Bay Sauvignon Blanc, Handpicked Wines Pinot Noir, and Moët Grand Vintage. Not that I plan on using it (I simply could not justify the prices) but it’s a nice extra that makes the room feel that much more luxurious. The drinks lineup reads like a who’s-who of local favourites Young Henrys, Maybe Sammy cocktails, Four Pillars gin and Archie Rose gin. Snacks include Tyrell’s chips, Pringles, Natural Confectionery lollies, and a Carman’s oat bar. 

Some small touches I appreciate that some hotels don’t offer: the option to choose your housekeeping time, an iron that actually works well, a Bluetooth speaker, the beloved wine fridge, aluminium water bottles and a bathroom without a glass door or screen that awkwardly exposes you. The one downside is that some of these rooms don’t offer much in the way of a view.

4:30pm is Swill Hour a daily tradition that nods to the historical “six o’clock swill” in Australia. This one-hour event takes place in the Living Room and invites guests to gather and enjoy each other’s company with a signature cocktail in hand. This afternoon’s tipple is a Eucalyptus Gimlet, a clever, herbaceous little cocktail, by the multi-award-winning Maybe Sammy Team, served on coasters depicting drawings of the historic building. The canapé of the day is a tomato and stracciatella tart. I noticed several staff members chatting with guests like old friends, asking how their adventures earlier in the day went clearly remembering previous conversations from earlier visits. 

Dinner is booked for 6:30pm in Aperture arguably the most beautiful area of the accommodation. It’s decorated with Australian flora and features a kinetic sculpture hanging from the roof that opens like flowers, with softly changing lights. Tyler, who is serving us, clearly admires the Capella brand, speaking enthusiastically about the other international properties he’s been to and sharing how he sometimes brings his five-year-old daughter here to use the pool.

The scale of Aperture gives it an international feel.

I kick things off with a basil melon margarita a winning recommendation before tucking into the best prawn toast I’ve ever had. For mains it’s crispy Ōra King salmon and spaghetti with mud crab. 

When I arrive back at my room, there’s a vegan leather journal on my bed with a note that says: “The ritual of journaling allows us to pause, reflect and focus.” This is part of the turndown service, and my slippers are neatly lined up next to my bed. Will I journal? No. Do I think it’s a nice touch? Yes.

The next morning, I make the predictable choice of smashed avo for breakfast at the on-site restaurant, Brasserie 1930. There’s also a buffet brimming with all the usual suspects.

Afterwards, I head to the pool to relax for a few hours before the 11am checkout. Despite my earlier resolve not to journal, I find myself reflecting nonetheless – an irony not lost on me – on my 21st hotel stay in Sydney. I write this with growing assurance that great hotels don’t just provide a place to stay; they create memorable moments, thanks in large part to fantastic staff. Kudos to the hiring manager.
