Best Things to Do on Kangaroo Island in May

The onset of winter brings a slower pace to Kangaroo Island in May. The cooler temperatures and increased rainfall are perfect for enjoying the island’s cosy indoor experiences, while still presenting plenty of opportunity to get outdoors and explore. Whether you’re looking to get up close with wildlife, explore underground caves, or warm up with a local brew, May offers plenty of activities to make the most of your trip. Here are some of the best things to do on Kangaroo Island in May.

Kangaroo Island Wildlife Park

The animals really do come alive in the winter months, as the cooler weather brings them out and makes them much more active during the daytime. At Kangaroo Island Wildlife Park, you can get up close and personal with many different creatures, including the cuddly koalas. During your visit, you can learn all about where they live, their diets and the challenges they are currently facing in the wild.

You can also see the kangaroos, echidnas and a variety of bird species. Kangaroo Island Wildlife Park is committed to the conservation and care of native Australian animals, so it’s a chance to contribute to this ongoing work while learning more about Australian wildlife.

Kelly Hill Caves

Ready to step back in time? Kelly Hill Caves on Kangaroo Island is a must-do activity in the cooler months. Known for their incredible limestone creations, you can glimpse into the geological history of the region as you explore stalactites and stalagmites that have been formed over thousands of years underground.

You can take an audio-visual tour with narration to experience an immersive history of the caves as you wander through. Start above ground and learn all about the caves’ history before you head underneath. And if you have a sense of adventure, you can even crawl, climb, and squeeze your way through lesser-known parts of the cave system.

Emu Ridge Eucalyptus Oil Distillery

As the temperatures cool down in May, there’s no better place to warm up and experience a slice of Kangaroo Island’s history than at the Emu Ridge Eucalyptus Oil Distillery. This iconic distillery is the only commercial eucalyptus oil distillery in South Australia, and it has been producing high-quality eucalyptus oil since 1991. 

Guided tours take you through the process of eucalyptus oil production, from harvesting the native eucalyptus leaves to distilling the oil using age-old techniques. You’ll have the chance to see the distillery in action and learn about the various uses of eucalyptus oil, from natural remedies to eco-friendly cleaning products.

After the tour, you can sample skincare items, soaps, and delicious local honey before enjoying a hot drink or a light meal in the distillery cafe or checking out the cellar door for Kangaroo Island Ciders.

Wildlife Safari

As the sun sets over Kangaroo Island in May, the island’s wildlife begins to stir, making it the perfect time for a dusk wildlife safari. The cooler evening temperatures and early sunset are ideal for spotting the island’s nocturnal animals as they become more active. A guided wildlife safari at dusk offers a unique opportunity to experience Kangaroo Island’s diverse fauna in their natural habitat.

With an experienced local guide, you’ll learn about the behaviours and habitats of these animals, as well as the best spots to watch them as they play and interact. Spot Stone Curlews, Boobook Owls, Brush-tailed Possums and maybe even an Echidna. See the Kangaroos grazing in open grasslands, or discover the Wallabies hiding in the shrublands.

May on Kangaroo Island offers a unique blend of adventure, and cosy comfort as the island transitions into winter. The cooler weather and shorter days are perfect for exploring the natural beauty, whether you’re cuddling a koala at the wildlife park, exploring the depths of Kelly Hill Caves, or warming up by a fire with a hearty meal.
