Hallett Cove Boardwalk

The Hallett Cove Boardwalk traces the dramatic coastline of the Hallett Cove Conservation Park, on Adelaide's southern shore. This excellent clifftop boardwalk and trail leads you past one of the most geologically significant sites in the country — ancient rock formations, sculpted cliffs and the striking Sugarloaf, revealing hundreds of millions of years of Earth's history, including evidence of an ancient glacial period.

The appeal is that combination of an easy, accessible walk and genuinely remarkable scenery: sweeping coastal views, fascinating geology and interpretive signs that bring the deep-time story to life along the way. It's a rewarding outing that pairs a scenic stroll with a real sense of wonder, all within easy reach of the city.

With a 4.7 rating from more than 1,100 reviews, it's a much-loved spot. The boardwalk is free and open, but conditions are exposed to the coastal weather and sections can be uneven, so it's worth checking conditions before you go — and taking water, sun protection and sturdy footwear, and allowing time to read the interpretive signs that explain the extraordinary geology beneath your feet.
