The centre’s commitment to conservation and education ensures that your experience is both enjoyable and respectful of the penguins’ natural habitat.
Swimming with Wild Dolphins at Kangaroo Island Marine Adventures
If you’re after an unforgettable experience that will stay with you for years to come, book in to swim with wild dolphins at Kangaroo Island Marine Adventures. Take a ride onboard their custom-built dolphin swim jet boat, Energizer, where they will take you to the best spots to see the dolphins in the wild.
At the beginning of March, while the weather is still nice and warm, you might have the opportunity to swim with up to as many as 50 to 80 dolphins. Once the dolphins are spotted, you can slip into 1-3 metre deep water and swim alongside them.
There is also plenty of room to relax back on the boat and take plenty of photos as the dolphins swim and play around you.
A Scenic Ferry Experience
Before the weather starts to cool down, March is the perfect time of year to take a ferry ride to and from Kangaroo Island. Many tourists are often too caught up in the destination to sit back and enjoy the ride, which offers plenty of stunning scenery right before your eyes. The ferry takes you across the waters of the Backstairs Passage, where you’ll be treated to stunning views of the South Australian coastline and the island’s shores. You should also keep your eyes peeled for dolphins, seabirds, and even whales along the way.
Learn about Bees at Clifford's Honey Farm
Bees are big business on Kangaroo Island (at least the honey is!) and Clifford's Honey Farm offers a glimpse into the world of bees and the art of beekeeping. As you explore the farm, you’ll learn about the unique Ligurian bees, known for their gentle nature and the pure, high-quality honey they produce.
The farm provides tours where you can see the bees at work in glass hives, watch the honey extraction process, and gain insights into the role bees play in our ecosystem. After learning about the bees, you can sample a variety of honey products made on-site, including the farm’s famous honey ice cream.
Enjoy a Drink or Dinner at Sunset Food & Wine
Sunset Food & Wine is a modern bistro that overlooks America Beach. It was the first restaurant on Kangaroo Island to be awarded one Chef Hat from the Australian Good Food Guide in 2017, so you know you’re going to sample some delicious food. Whether you’re enjoying a leisurely lunch, a romantic dinner, or just a glass of wine, you’re in for a treat.
As the name implies, the real magic happens as the sun begins to set. The restaurant’s outdoor terrace provides the perfect vantage point to watch the sun dip below the horizon, as all the gorgeous colours cast a glow on the water. It’s the perfect way to soak up some natural beauty at the end of a busy day.
March is a fantastic time to explore Kangaroo Island, with its mild temperatures and daylight hours that welcome in the autumn months. The island’s endless landscapes, unique wildlife, and vibrant local culture come alive in this season, offering plenty of opportunities for adventure, relaxation and discovery.
