Road trip: The Limestone Coast in 4 days

You'll find all the delights of a seaside village and more in lively Glenelg, which sits in Holdfast Bay, a 20 minute drive from Adelaide's centre. Water babies can swim with wild dolphins, go diving or snorkelling, or join a fishing charter, and history buffs can trace Glenelg's history in the galleries and museums.

The McLaren Vale wine region beckons the next morning, where over 85 wineries – some well over 100 years old – are packed into the small, mountainous area above Adelaide’s southern beach suburbs. Visit d’Arenberg, which is run by a fourth-generation winemaker and uses vines planted as far back as 1900, and book yourself in for one of its ‘Blending Bench’ experiences. For a few hours you can pretend to become a celebrated winemaker, tasting a selection of drops and then combining them into my own signature blend.

The days are long in South Australia through summer and with plenty of light left so you can make the most of exploring the area. Take the hour-long stroll across to Granite Island, where you can ride an historic horse-drawn tram over the wharf. From the island the views are amazing and it’s calming to sit on the leeward side, out of the wind and in the afternoon’s warmth.

Have a leisurely start (and breakfast pie) the next morning, and make your way to Goolwa Wharf, 10 minutes down the road, and jump aboard a Cruise the Coorong tour, exploring the Murray River mouth. On your way out you have to pass through the Goolwa Barrages, where seals are waiting for an easy feed at the gates that were built to help regulate the Murray’s flow.

The eastern side of the mouth marks the beginning of the Coorong, a 160km long wetland and dune system that runs to the township of Kingston SE. Jump off the boat at Barker’s Knoll and learn of the area’s significance to Indigenous people, and forage for bush tucker such as native spinach, muntrie berries and, my favourite, pigface fruit. Most of the foods native to the area are in season in January. Interestingly, this part of the Coorong is home to Australia’s first Aboriginal mission and the first child born there is featured on our $50 note. David Unaipon of the Ngarrindjeri peoples was an inventor, author and influential Aboriginal rights advocate.

Make a trip to the Naracoorte Caves National Park the following morning, and join the Victoria Fossil Cave tour, which takes us through a limestone cave formed over hundreds of millions of years when this area was under the sea (not 100km inland). Later on there must have been a hole into this particular cave system, which animals, especially mega fauna, fell in and died. Soil then built up over time and there’s now a significant cache of well-preserved fossils. Interestingly, one of the people who theorised much of the Limestone Coast is in fact a series of much older coastlines, was Julian Tenison-Woods – the Catholic priest who worked alongside Australia’s first saint, Mary Mackillop. Visit the museum dedicated to the pair in Penola for a short 20 minute break.

Continue your journey into the past at the Rymill Coonawarra winery. It’s next-door to the property at which Mary McKillop first started teaching, and the family who established the winery make regular appearances in her story. Over five generations, this family has excelled at wine making and their high achievements don’t end there. John Riddoch Rymill was a famed explorer and led the 1934 British Graham Land Expedition, mapping over 1,000km of the Antarctic Peninsula. Whilst there, enjoy a fine cheese platter in the shade of the quiet garden.
