Great South West Walk - Victoria's Coastal Odyssey
The Great South West Walk is a monumental 250-kilometre loop trail that showcases the raw, untamed beauty of Victoria’s far southwest corner. Starting and finishing in the historic maritime town of Portland, this journey is a masterclass in ecological diversity, traversing four distinct landscapes: rugged coastal cliffs, the majestic Glenelg River, the vast dunes of Discovery Bay, and the ancient, towering stands of the Cobboboonee Forest. Established in 1981 by the Friends of the Great South West Walk, the trail was designed to provide a world-class long-distance walking experience that remains accessible yet profoundly challenging. Unlike many linear tracks, the loop format offers a sense of completion that is rare in the hiking world, beginning at the edge of the Southern Ocean and returning there after a fortnight of immersion in the wild.

Overview
The Great South West Walk is often described as four walks in one, each offering a completely different sensory experience. The first stage leads walkers away from the industrial heritage of Portland and into the deep, silent world of the Cobboboonee Forest. Here, the air is cool and scented with eucalyptus, and the path winds through stands of Messmate and Peppermint gums. This section is a haven for birdlife, where the screech of Yellow-tailed Black Cockatoos echoes through the canopy and Eastern Grey Kangaroos graze in the dappled light of the understory. The transition from the forest to the river marks the beginning of the second stage.
The Glenelg River section is perhaps the most serene part of the journey. For over 70 kilometres, the trail follows the winding path of the river as it carves through spectacular limestone gorges. The cliffs, some rising 50 metres above the water, are a pale honey colour, reflecting in the glassy surface of the river. This is a landscape of quiet reflection, where the only sound is the rhythmic dip of a canoeist's paddle or the splash of an Azure Kingfisher. The trail here is well-shaded and relatively flat, providing a welcome reprieve before the physical demands of the coastal sections.
The third stage, Discovery Bay, is where the Great South West Walk earns its reputation for being a true wilderness challenge. This 50-kilometre stretch of coastline is dominated by massive, shifting sand dunes and the relentless power of the Southern Ocean. Walking on the beach requires careful timing with the tides and a high level of physical endurance, as the soft sand can be punishing on the legs. However, the reward is a sense of absolute isolation; it is not uncommon to walk for days here without seeing another human soul, with only the tracks of emus and dingoes in the sand for company.
The final stage brings walkers along the dramatic "Capes" section—Cape Nelson and Cape Bridgewater. These are some of the highest coastal cliffs in Victoria, offering panoramic views across the ocean where Southern Right Whales can often be spotted during their migration. The trail passes through the "Petrified Forest" and the "Blowholes," geological wonders that highlight the volcanic and erosional history of the region. As the loop closes back toward Portland, walkers are treated to a final display of coastal grandeur, finishing where they began with a profound new appreciation for the resilience of the Australian landscape.
History and Cultural Context
The Great South West Walk is situated on the traditional lands of the Gunditjmara people, who have maintained a deep spiritual and physical connection to this country for tens of thousands of years. The region is home to the Budj Bim Cultural Landscape, a UNESCO World Heritage site located just north of the trail, which features one of the world’s oldest and largest aquaculture systems. The Gunditjmara used the volcanic rock of the area to create complex channels and weirs to harvest eels, demonstrating a sophisticated understanding of land management and engineering. Throughout the walk, particularly along the Glenelg River and the coastal capes, the landscape is rich with cultural significance, including shell middens and sites of ancestral importance.
The modern history of the trail is a testament to community spirit and volunteerism. In the late 1970s, Bill Golding, a local resident and visionary, conceived the idea of a long-distance walking track that would showcase the natural beauty of the Portland region. In 1981, the Friends of the Great South West Walk was formed, and through thousands of hours of volunteer labour, the trail was cleared, marked, and infrastructure was built. Unlike many state-managed trails, the GSWW was born from the grassroots, and to this day, the Friends group remains integral to its maintenance and promotion, working in partnership with Parks Victoria.
The trail also passes through areas of significant European maritime history. Portland was the site of Victoria's first permanent European settlement, established by the Henty brothers in 1834. The coastline is notorious for its treacherous waters, and the trail passes near the sites of numerous shipwrecks, as well as the historic Cape Nelson Lighthouse, which has guided mariners since 1884. This layer of history—from ancient indigenous heritage to colonial exploration and modern conservation—gives the Great South West Walk a depth of character that enriches every kilometre of the journey.

Seasonal Highlights and Weather Reality
The Great South West Walk is located in a temperate maritime climate, but its position on the edge of the Southern Ocean means it is subject to the "Roaring Forties"—strong westerly winds that can bring rapid changes in weather. Choosing the right season is critical for both safety and enjoyment.
Autumn (March–May): This is widely considered the best time to hike the GSWW. The fierce heat of summer has dissipated, and the winter rains have not yet arrived in full force. Days are often clear and mild, with temperatures ranging from 15°C to 22°C. The winds are generally lighter, making the beach sections of Discovery Bay more manageable. This is also a great time for birdwatching as many species are active before the colder months.
Spring (September–November): Spring is the season of wildflowers. The heathlands of the capes and the understory of the Cobboboonee Forest erupt in a vibrant display of orchids, wattles, and heath. The weather is cooler and more variable than autumn, with occasional showers, but the landscape is at its most lush and green. This is also the peak time for whale watching, as Southern Right Whales and Blue Whales frequent the waters off Portland and Cape Bridgewater.
Summer (December–February): Summer can be extremely challenging. Temperatures can soar above 35°C, and the risk of bushfires is a serious concern. Many sections of the trail, particularly in the forest and along the river, may be closed on days of Total Fire Ban. Water management becomes critical, and the lack of shade on the Discovery Bay beach section can lead to heat exhaustion. Hiking during this period is only recommended for very experienced walkers who are well-prepared for extreme heat.
Winter (June–August): Winter brings the most rain and the strongest winds. While the forest and river sections can be quite beautiful in the mist, the coastal sections can be brutal. High tides and storm surges can make the Discovery Bay beach walk dangerous or impossible. However, for those who enjoy solitude and don't mind the cold (temperatures often drop to 5°C at night), winter offers a raw and powerful perspective of the Southern Ocean.

Essential Preparation
The Great South West Walk is a significant undertaking that requires thorough physical and logistical preparation. Because it is a 250-kilometre loop, walkers must be capable of carrying a full pack (typically 15–20 kg) for up to two weeks. Fitness training should include long-distance walks with a weighted pack, ideally on varied terrain including sand. Portland is the primary base for the walk, offering all necessary services including supermarkets, outdoor stores, and long-term parking at the Visitor Information Centre. It is highly recommended to spend a night in Portland before starting to finalise gear and register your intentions with the local authorities.
Logistically, the most important factor is food. While Nelson (Day 8) offers a small general store for basic resupply, most walkers choose to cache food at specific points or carry the full amount. Some local transport operators offer food drop services for a fee, which can significantly lighten your load. Water is available at all 14 campsites via rainwater tanks, but its availability depends on recent rainfall, and it must be treated before consumption.
Trail Accommodation
Accommodation on the Great South West Walk consists of 14 purpose-built walkers' campsites. These sites are spaced approximately 15 to 20 kilometres apart, allowing for a consistent daily rhythm. Each campsite is designed to provide a basic but comfortable wilderness experience.
Campsite Facilities:
- Cleared tent sites (usually on sand or dirt)
- A three-sided shelter with a table and benches
- A rainwater tank (collection from the shelter roof)
- A pit toilet (toilet paper is usually provided but bring your own as a backup)
- A shared fireplace (subject to seasonal fire restrictions)
What is NOT Provided:
- Power or charging stations
- Rubbish bins (all waste must be carried out)
- Showers or laundry facilities (except in the town of Nelson)
- Bedding or mattresses
- Cooking equipment or fuel
Booking Requirements:
- All campsites must be booked in advance through the Parks Victoria website.
- The cost is approximately $15.00 to $20.00 per site, per night (subject to change).
- During peak periods (Easter and school holidays), sites can fill up, so early booking is advised.
- Camping is only permitted in the designated walkers' camps to protect the surrounding environment.
Required Gear
- Footwear: High-quality, broken-in hiking boots with good ankle support. Gaiters are essential for protection against sand, scrub, and snakes.
- Pack: A 60–75L trekking pack with a comfortable harness and a waterproof rain cover.

- Repair Kit: Duct tape, needle and thread, and sleeping mat patches.
Permits
While there is no "permit" required to walk the trail itself, you must book and pay for your campsites through the Parks Victoria booking system. This acts as your permit and ensures that the campsites do not become overcrowded, preserving the wilderness experience for everyone. It is also a requirement to register your walk at the Portland Visitor Information Centre before you depart. This is a free service and is vital for search and rescue purposes should an emergency occur.
Booking Process:
- Visit the Parks Victoria website and navigate to the "Great South West Walk" booking page.
- Select your start date and the number of people in your group.
- You must book each individual campsite for the specific night you intend to stay there.
- Payment is made via credit card at the time of booking.
- Keep a digital or printed copy of your booking confirmation with you on the trail.
Important Considerations:
- Group Size: Group sizes are generally limited to 8–12 people to minimise environmental impact. Larger groups must contact Parks Victoria for special permission.
- Cancellations: Refunds are generally not provided for changes in weather, so ensure you have adequate travel insurance.
- Fire Restrictions: During the summer months, Total Fire Bans are common. During these times, no fires (including fuel stoves) may be used in certain areas. Always check the Country Fire Authority (CFA) website for daily updates.
Other Activities in the Area
The region around Portland and the Glenelg River offers numerous opportunities to extend your adventure or relax after your walk:
- Canoeing the Glenelg River: If 250 km of walking isn't enough, you can hire a canoe in Nelson and paddle the limestone gorges. Many of the walkers' camps are also accessible by water, allowing for a "paddle and hike" multi-sport trip.
- Budj Bim National Park: Located a short drive from Portland, this park offers shorter walks through volcanic landscapes, including lava tubes and a crater lake. It is a site of immense cultural significance to the Gunditjmara people.
- Whale Watching: From June to October, Portland is one of the best places in Australia to see Southern Right Whales. Cape Bridgewater and the Portland harbour are prime viewing spots.
- Surfing: The beaches around Cape Bridgewater and Discovery Bay offer world-class (and often very powerful) surf breaks for experienced surfers.
- Portland Maritime Discovery Centre: A great place to learn about the shipwrecks, whaling history, and natural history of the region before or after your walk.
- Princess Margaret Rose Cave: Located near the Glenelg River, this spectacular limestone cave offers guided tours of its intricate stalactites and stalagmites.
Safety and Conditions
Weather and Exposure: The most significant safety risk on the GSWW is exposure to the elements. The coastal sections are extremely exposed to wind, rain, and sun. Hypothermia is a risk even in summer if you are caught in a cold Southern Ocean storm. Conversely, heat exhaustion is a major threat on the beach sections. Always check the Bureau of Meteorology (BOM) forecast for "District: South West" before departing and carry adequate clothing for all conditions.
Water Management: While tanks are provided at campsites, they are not guaranteed to be full. In dry years, water levels can be critically low. Always carry at least 3–4 litres of water, especially on the Discovery Bay and Capes sections where there is no shade. Never rely on finding water between campsites.
Snakes: The region is home to several species of venomous snakes, including the Tiger Snake and the Lowland Copperhead. They are most active in spring and summer. Always wear gaiters, watch where you step, and carry a specific snake bite bandage (and know how to use it). If you encounter a snake, stop, remain still, and allow it to move away.
Tides and Beach Walking: The 50 km stretch of Discovery Bay involves significant beach walking. At high tide or during storm surges, the beach can become narrow or impassable, forcing you into the soft sand of the dunes, which is exhausting. Check tide charts before you leave Nelson and aim to walk the beach sections on a falling or low tide.
Cliff Safety: The cliffs at Cape Bridgewater and Cape Nelson are spectacular but dangerous. They are composed of limestone and volcanic rock which can be unstable. Always stay on the marked trail and never approach the edge of the cliffs, as undercutting is common and falls are fatal.
Emergency Communication: Mobile phone reception is patchy at best and non-existent in many sections of the forest and Discovery Bay. A Personal Locator Beacon (PLB) is considered essential equipment for this trail. In an emergency, a PLB is the only reliable way to signal for help.
Side Trips and Points of Interest
The Petrified Forest: Located on the tip of Cape Bridgewater, this is not actually a forest of trees but a collection of hollow sandstone tubes formed by the erosion of ancient dunes around tree trunks. It is a surreal, moon-like landscape that is a highlight of the final stages of the walk.
The Blowholes: Right next to the Petrified Forest, the Blowholes are a series of vents in the volcanic rock where the Southern Ocean swells are forced through, creating spectacular plumes of spray and a thunderous sound. They are most impressive during high seas.
Cape Bridgewater Seal Colony: A side trip from the main trail leads to a viewing platform overlooking a colony of hundreds of Australian Fur Seals. You can see them basking on the rocks or playing in the surf below the 200-metre high cliffs. Boat tours from Portland also visit the colony for a closer look.
Tarragal Caves: These massive limestone sea caves are located across the road from the Tarragal campsite. They offer a great vantage point over Discovery Bay and are a fascinating geological feature to explore.
Point Danger Gannet Colony: Located just outside Portland, this is the only mainland breeding colony of Australasian Gannets in Australia. The sight of thousands of birds nesting and diving into the ocean is a spectacular way to end the walk.
Leave No Trace
The Great South West Walk passes through fragile coastal and forest ecosystems that are easily damaged by human activity. Adhering to Leave No Trace principles is essential to ensure the trail remains pristine for future walkers and to protect the habitat of local wildlife.
Key Principles for the GSWW:
- Plan Ahead and Prepare: Ensure you have the correct maps, enough food, and a reliable way to treat water. Know the fire regulations for the day.
- Travel and Camp on Durable Surfaces: Stay on the marked trail at all times. In the dunes, walking off-track can cause significant erosion and destroy sensitive vegetation. Only camp in the designated walkers' campsites.
- Dispose of Waste Properly: Pack it in, pack it out. This includes all food scraps (even "biodegradable" ones like orange peels), tea bags, and hygiene products. Use the provided pit toilets at campsites.
- Leave What You Find: Do not collect shells, rocks, or wildflowers. Respect the cultural heritage sites of the Gunditjmara people by not touching or disturbing middens or stone arrangements.
- Minimise Campfire Impacts: Use a fuel stove for cooking. Only use the provided fireplaces at campsites if there is no fire ban, and keep fires small. Ensure the fire is completely extinguished with water before leaving.
- Respect Wildlife: Observe animals from a distance. Do not feed kangaroos, emus, or birds, as this can make them aggressive or sick. Store your food securely to prevent animals from raiding your pack.
- Be Considerate of Other Visitors: Keep noise levels down, especially at campsites. The GSWW is a place for solitude and natural sounds.
