Kangaroo Island: The Highlights

Kangaroo Island is one of those rare places where wildlife, rugged beauty, and untouched wilderness collide. One moment, you’re gazing at cliffs plunging into turquoise seas; the next, you’re nose-to-nose with a sleepy koala in a gum tree. Throw in sea lion colonies, dramatic rock formations, and secluded beaches, and you’ve got a destination that feels worlds away from the everyday.

If you’re wondering what to do on Kangaroo Island, this guide will take you through the must-see highlights, especially the ones you’ll experience when exploring with True North. A True North adventure brings a different level of access, allowing you to discover the island’s wild corners by sea, air, and land, all with expert guides leading the way.

Where is Kangaroo Island?

Kangaroo Island sits off the coast of South Australia, about 13 kilometres from the mainland, across the Backstairs Passage. It’s Australia’s third-largest island, stretching over 4,400 square kilometres, with a wild, windswept coastline and a population of just under 5,000 people.

Despite its size, much of Kangaroo Island remains protected and undeveloped. Over a third of the island is dedicated to national parks and conservation reserves, making it one of the country’s best places to encounter native wildlife in its natural habitat.

How to get to Kangaroo Island

By sea

Many travellers take the car and passenger ferry from Cape Jervis to Penneshaw. But when you explore with True North, you’ll arrive in style aboard a luxury small ship, giving you front-row access to the island’s spectacular coastline, without the crowds.

By air

Regular flights run from Adelaide to Kingscote Airport, or if you’re on board True North, you can take advantage of our onboard helicopter to experience the island from above. Few views match seeing the jagged cliffs and rolling green hills of Kangaroo Island from the sky.

Best time to visit Kangaroo Island

Summer (December – February)

Warm days and long evenings make this a great time for coastal adventures. Sea lion pups are active on the beaches, and it’s ideal for swimming and snorkelling.

Autumn (March – May)

Mild temperatures and fewer crowds. The landscape is still lush from the summer rains, and wildlife spotting is excellent.

Winter (June – August)

Cooler weather brings dramatic seas and the chance to spot southern right whales migrating offshore. It’s also peak time for koala sightings as they feed actively in the eucalypts.

Spring (September – November)

Wildflowers blanket the island, birdlife is abundant, and it’s a beautiful time for photography and coastal walks.

Top things to see & do on Kangaroo Island

The Remarkable Rocks

Perched high above the Southern Ocean, the Remarkable Rocks live up to their name. Sculpted by wind and sea over 500 million years, these massive granite boulders create surreal shapes that look like they belong on another planet.

On a True North adventure, you’ll often arrive here by tender boat or helicopter, avoiding the day-tripper crowds and giving you space to explore and photograph this geological wonder in peace.

Koala spotting in the wild

Few experiences rival spotting a wild koala, and Kangaroo Island delivers. In places like Hanson Bay, Flinders Chase National Park, and the island’s eucalypt forests, koalas are often seen lazing in the forks of trees or munching leaves. On True North guided excursions, you’ll be led to quieter areas where you can enjoy close, respectful wildlife encounters—no zoo fences, no staged settings, just nature.

The epic coastline

Kangaroo Island’s coastline is a study in contrast: sheer cliffs that plunge into the sea, hidden coves with crystal-clear water, and windswept island beaches where you can walk for kilometres without seeing another soul.

True North brings you right into the heart of this landscape. Whether cruising below the cliffs, landing in remote spots with the onboard helicopter, or venturing out in adventure boats, you’ll see parts of the island that most never do.

Sea lion and fur seal colonies at Seal Bay

At Seal Bay Conservation Park, a thriving colony of Australian sea lions sprawls across the sand. Watching these endangered animals up close, lounging, feeding, and tending their pups, is a highlight of any Kangaroo Island visit.

Nearby, rocky outcrops around Cape du Couedic and Admirals Arch are home to playful fur seal colonies. Seeing these agile creatures darting through the water and sunbathing on the rocks is always a crowd favourite on True North coastal excursions.

Cape du Couedic Lighthouse

Standing watch over the island’s rugged southwest, Cape du Couedic Lighthouse is an icon of Kangaroo Island. Built in 1909 to protect ships from the treacherous coastline, it remains an atmospheric spot to visit, especially at sunrise or sunset when the cliffs below are bathed in golden light.

A True North cruise gives you the perfect vantage point to view the cliffs and lighthouse from the water, a perspective few visitors get to enjoy.

Kangaroo Island Wildlife Park

For even closer encounters, a visit to Kangaroo Island Wildlife Park offers the chance to learn about and support the conservation of local species. Here, rescued animals including koalas, echidnas, kangaroos, and reptiles are cared for by dedicated staff. It’s a great stop for families and wildlife lovers alike.

Penguin Centre

In Penneshaw, the Penguin Centre runs informative evening tours that let you see the island’s smallest residents, little penguins, waddling ashore after a day at sea. With expert guides, you’ll gain insight into their fascinating behaviours while ensuring the experience remains safe and respectful for the birds.

American River

The tranquil village of American River is a haven for birdwatchers and seafood lovers. Known for its oyster farms and serene inlet, it’s also a great spot to kayak, fish, or simply enjoy the peaceful scenery. When exploring with True North, you’ll often cruise through this area and have the chance to sample some of the island’s freshest local produce.

Stokes Bay

A hidden gem on the north coast, Stokes Bay is famous for its secret beach, accessed through a maze of rocks. The sheltered lagoon is ideal for swimming, and the surrounding landscape is one of the island’s most photogenic spots. Many True North guests count this as a favourite beach day on their cruise itinerary.

Tips for exploring Kangaroo Island

Bring your camera

From sweeping coastal vistas to close encounters with wildlife, Kangaroo Island is a photographer’s dream. If you’d prefer to simply soak it all in, True North’s onboard expedition photographer is always ready to capture the magic for you.

Respect the wildlife

Kangaroo Island is a haven for local wildlife. Whether it’s a koala in a gum tree or a fur seal basking on the rocks, always maintain a respectful distance and follow your guide’s advice to minimise disturbance.

Pack layers

The weather can change quickly, especially along the coast. Lightweight layers, sun protection, and sturdy shoes will keep you comfortable on land and sea excursions.

The best way to experience Kangaroo Island

Kangaroo Island is a land of wild beauty and close up wildlife encounters, best explored with expert guidance and a spirit of adventure. On a True North cruise, you’ll see it from every angle, cruising along the coast, flying high above in the onboard helicopter, and landing in places few visitors reach.

It’s not just about ticking off the highlights. It’s about experiencing them in a way that’s immersive, luxurious, and unforgettable. From the Remarkable Rocks to Stokes Bay, Cape du Couedic Lighthouse, and the fur seal colonies, every moment with True North puts you closer to the heart of this remarkable island.
