Since the Great Ocean Walk officially opened in 2006, Walk91 has proudly helped thousands of walkers explore this breathtaking 104km coastal trail in southwest Victoria.
Founded by locals who helped build and promote the trail, we know this coastline like the back of our hand — because it’s our backyard. Walk91’s founder, Mark Kininmonth, is an ex-Parks Victoria Ranger and even helped construct sections of the Great Ocean Walk itself.
Our Self-Guided Great Ocean Walk Tours allow you to walk at your own pace, with expert local insight, detailed maps, transport logistics and support — so you can focus on enjoying the journey.
One of the most common questions we’re asked is:
“What’s the difference between the Mild Side and the Wild Side of the Great Ocean Walk?”

The Mild Side of the Great Ocean Walk
Apollo Bay to Castle Cove (approx. 50km)
When Parks Victoria designed the Great Ocean Walk, they referred to the eastern half of the trail — from Apollo Bay to Castle Cove — as the Mild Side.
This section is more accessible and flexible, with:
- Shorter daily walking distances
- Fewer steep climbs
- More step-on, step-off access points
- Easier connections to accommodation
It’s ideal for walkers who want a moderate challenge, those new to multi-day walking, or anyone looking for flexibility in their itinerary.
You’ll walk through towering eucalypt forests, sheltered bays and coastal headlands, often finishing each day close to civilisation — without losing that feeling of immersion in nature.
Highlights of the Mild Side
- Apollo Bay Trailhead – Begin beside the Visitor Information Centre and follow the trail past the harbour and foreshore.
- Marengo to Shelly Beach – Gentle coastal walking past Halley’s Reef and the Marengo Marine Sanctuary.
- Blanket Bay – A calm, protected bay nestled between forested headlands.
- Parker Inlet – Home to the historic Eric the Red shipwreck, sometimes visible when the sand shifts.
- Cape Otway Lighthouse – One of Australia’s oldest light stations, with sweeping ocean views and rich maritime history.
- Cape Otway Cemetery – A poignant reminder of the region’s shipwreck and settlement past.
- Rainbow Falls – An optional detour to a unique cliffside waterfall fed by mineral-rich groundwater.
- Aire River – A tranquil, heritage-listed crossing known for birdlife such as herons and black swans.
- Castle Cove – Finish with spectacular cliff-top views and unforgettable sunsets.
💡 Walk91 Tip:
If the Mild Side sounds like your ideal adventure, our 3-Day Hike the Cape Walk is a perfect introduction to the Great Ocean Walk, combining highlights with expert local support.
🌊 The Wild Side of the Great Ocean Walk
Castle Cove to the 12 Apostles (approx. 58km)
The western half of the trail — from Castle Cove to the 12 Apostles — is known as the Wild Side, and it truly earns its name.
This is where the Great Ocean Walk becomes more remote, rugged and dramatic. Expect:
- Longer days (more of a commitment to walk longer/harder distances)
- Steeper climbs and descents
- Fewer access points (where you may exit the trail)
- Vast, untamed coastal scenery
Walkers on the Wild Side often go hours without seeing another person. The sense of isolation, scale and raw coastal power is what makes this section so unforgettable.
Highlights of the Wild Side
- Johanna Beach – A huge, wild surf beach once used as a backup venue for the Bells Beach Surfing Classic.
- Milanesia Beach – One of the most remote and atmospheric sections of the trail.
- Moonlight Head & The Gables – Towering cliff-top viewpoints with jaw-dropping coastal panoramas.
- Wreck Beach – A steep descent (tide permitting) to see the anchors of the Fiji and Marie Gabrielle embedded in the sand.
- Princetown Wetlands – A peaceful landscape filled with kangaroos, wallabies and birdlife as you near the end.
- Gibsons Steps & the 12 Apostles – Finish your journey at one of Australia’s most iconic natural landmarks.
💡 Walk91 Tip:
For walkers craving solitude and dramatic landscapes, our 3-Day 12 Apostles Walk or 4-Day Wild Walk showcase the very best of this remote section.
Mild Side vs Wild Side: Which Should You Choose?
Both sections are spectacular — the difference lies in access, terrain and commitment.
- Choose the Mild Side if you want flexibility, gentler terrain and easier logistics.
- Choose the Wild Side if you’re seeking remoteness, big coastal drama and a true wilderness feel.
- Can’t decide? Many walkers do the Mild Side first and return later for their “Part Two” on the Wild Side.
You can also walk:
- Just the Mild Side
- Just the Wild Side
- Or the entire Great Ocean Walk in 5, 6, 7 or even 10 days
