Visitors can now explore historic underground tunnels on the Mornington Peninsula.

At the very tip of the Mornington Peninsula sits a fascinating part of Australia’s history. Fort Nepean cuts a dramatic figure on the coastline of Point Nepean National Park, built to defend Melbourne in the First and Second World Wars. It was here that the first shot of the First World War was taken for the British Empire, and Australia’s opening shot of the Second. And now, for the first time since the wars, visitors can also head underground and explore the historic Fort Nepean tunnels.

What’s inside the tunnels?

Heading underground, visitors will be able to follow a web of narrow corridors carved into limestone, spreading out underneath Fort Nepean. Highlights underground include old ammunition stores and bomb-proof chambers, remnants of its military past.

Above ground, beyond dramatic vistas of the surrounding coastline, visitors can spot historic gun emplacements.

When were the tunnels sealed?

After the Second World War, in 1945, Fort Nepean was permanently sealed and closed to the public after the site’s coastal artillery was removed. The whole area remained closed to the public for another 40-plus years, being used as a restricted military training area.

Then, in 1988, it was opened back up as a public area, as part of Point Nepean National Park. But it’s only now that the labyrinth of underground tunnels has been part of that equation.

Why are they open now?

Work to “remedy structural issues, and conserve and repair concrete structures across the site" has been done as part of the Victorian Government’s Heritage Icons Project. So, essentially, the tunnels are now structurally safe to walk through. The work was aimed at both preserving the history and character of the site while safeguarding its future.

Getting to Fort Nepean

Getting to the Fort Nepean tunnels does require a walk, but it’s considered one of the most beautiful coastal trails in Victoria. And there are a couple of options.

For a shorter walk, follow the approximately 1.6-kilometre (one-way) Gunner’s Cottage route. Follow this sealed road from Gunners Car Park, passing the historic Point Nepean Cemetery along the way.

Those feeling more energetic can opt for the approximately 16-kilometre (return) pathway from Point Nepean Quarantine Station. From there, follow the signposted coastal and sealed road track through coastal scrub and rugged cliffside scenery. Look out over Phillip Bay, Bass Strait and The Rip, and even plan to stop at dedicated picnic areas along the way.

Don’t want to walk at all? Wait for the hop-on, hop-off shuttle running through the national park. It connects the park entrance with Quarantine Station and Fort Nepean. You can also opt for a combo of shuttle and hiking.

8 experiences to get the most out of Victoria’s Great Ocean Road

    Louis Costello Louis Costello
    Continue
    Beyond the winding bitumen and coastal views lies another side to Victoria’s most famous route.

    There’s something hypnotic about this stretch of Victoria’s coast. Maybe it’s the way the road hugs the ocean so tightly, or how the cliffs catch the sun in colours you can’t name. Or, for local Victorians who drove this route as kids, maybe it’s the memories of winding through the impossibly tall trees as they seemingly guide you on your journey like wooden guardian angels. Most travellers know it for the 12 Apostles, but there are plenty of alternate experiences on the Great Ocean Road equally as worthy of your time.

    So, next time you’re in that neck of the woods, park that car, stretch those legs and try these experiences.

    1. Discover living culture at Budj Bim

    Breakaway Creek’s Budj Bim Cultural Landscape is a masterclass in educational storytelling. Join a guided tour with Budj Bim Cultural Landscape Tourism to walk across the world’s oldest known aquaculture system, where the Gunditjmara people built sophisticated eel traps and stone channels more than 6,000 years ago.

    Budj Bim’s aquaculture system predates Egypt’s pyramids by roughly 2,000 years, making it one of the oldest examples of human engineering on Earth. If that’s not enough to get your history-loving family members involved in this road trip, we’re out of ideas.

    2. Unwind in the hot springs at Warnambool

    Let mineral-rich water heal you.

    If your legs need a break after a long drive, Deep Blue Hot Springs is your remedy. The geothermal pools sit just metres from the coastline, filled with mineral-rich water that bubbles up from deep underground. Move between open-air baths, waterfall pools and quiet zones made for meditation.

    The water in Deep Blue’s geothermal pools comes from an ancient aquifer nearly 850 metres below the Earth’s surface, which, in non-scientific terms, means it’s far more likely to have healing properties than the mineral water you’d find at the supermarket.

    3. Take to the air at Princetown

    You may have seen the Twelve Apostles from the trusty viewing platform, but a helicopter flight with 12 Apostles Helicopters shows you just how sprawling and rugged this coastline really is.

    The trip covers everything from Port Campbell to London Bridge (not to be confused with the UK’s own), giving you a rare chance to watch waves carving the limestone cliffs from above. It’s worth noting that the limestone stacks of the Twelve Apostles are said to erode by roughly two centimetres each year, so the longer you leave it, the less of the Apostles you’ll see.

    4. Step into the past at Flagstaff Hill

    Visit a time of yore.

    Continue the tour through Warnambool at Flagstaff Hill Maritime Village and Museum, a recreated 19th-century port town. Hear stories from the days when shipwrecks were as common as seagulls, with an astounding 180 ships believed to have sunk along the Shipwreck Coast in less than five years.

    The night show, complete with lights, sound, and sea spray, brings the coastline’s most dramatic stories to life.

    If you’re staying the night, Simon’s Waterfront offers relaxed dining with fresh local seafood and oceanfront views. Order the catch of the day and toast to the sailors who never made it ashore.

    5. Learn to surf in Torquay, Lorne, or Anglesea

    Whether you’ve surfed before or can barely stand on a board, Go Ride A Wave will have you upright in no time. Torquay’s calm beaches are ideal for first-timers, while Lorne and Anglesea bring a bit more energy for those unafraid to get dunked.

    Bells Beach, just down the road from Torquay, has even hosted the world’s longest-running professional surfing competition since 1962. So, for those eager to have a gander at pros using surfboards like they’re an additional appendage, the competition usually runs sometime in autumn.

    6. Tackle the trails in Forrest

    Hire a bike and explore MTB trails through the Otways.

    Forrest is a haven for mountain bikers thanks to an expansive network of trails through stunning natural scenery. The Forrest trail network has almost 100 kilometres of singletrack across 36 trails, so there’s something for every level of rider. That’s including more than 60 kilometres of purpose-built mountain bike trails winding through the Otways’ dense forest. Cycle through ancient myrtle beech trees and towering tree ferns, with smaller ferns and soft mosses forming a carpet at your feet.

    Hire a bike from Forrest MTB Hire and take your pick from easy, scenic rides to more challenging singletracks, such as Red Carpet or Rollercoaster.

    7. See wildlife up close in Apollo Bay

    If spotting koalas and kangaroos in the wild feels like winning the lottery, Wildlife Wonders gives you guaranteed sightings without cages or crowds. Every visit to the sanctuary helps fund the Conservation Ecology Centre which supports endangered species across the Otways, so your business is appreciated by humans and animals alike.

    The guided walk takes you through protected Otways habitat where you might spot potoroos (or joey lookalikes for those unfamiliar with a potoroo), wallabies, and sleepy koalas lounging in the trees.

    8. Visit the Cape Otway Lightstation

    Cape Otway Lightstation
    Delve into the tales of Cape Otway Lightstation.

    Towering over the sea on a cliff above the Southern Ocean, Cape Otway Lightstation has been guiding ships since 1848. Before the lighthouse was built, Cape Otway was one of the most treacherous points on the Victorian coast, with dozens of shipwrecks occurring in its surrounding waters. Pick the right day, and you may bump into a local willing to tell you about the wreck of Eric the Red.

    While at the Cape Otway Lightstation, explore the keeper’s quarters, walk the coastal trails, and take in views that only stop short at the horizon.

    And no, contrary to popular belief, the Round the Twist lighthouse is actually located in Split Point, just shy of two hours in the direction of Melbourne. Nothing’s stopping you from embarking on a lighthouse crawl, though.
