Trail summary
Hike overview
Enjoy a scenic 4km return hike (grade 3) through Flinders Chase National Park on Kangaroo Island. The Snake Lagoon Hike, starting at Snake Lagoon carpark, takes roughly 1.5 hours to complete and is perfect for those with moderate fitness levels.
The path winds through towering Sugar Gums and Mallee scrub, offering a cool, shaded start to your journey. Descend into the scenic Rocky River valley, where glimpses of unique rock formations and diverse flora will keep you engaged. A boardwalk guides you across the river, leading to the dramatic finale – the mouth where the river meets the Southern Ocean.
Be rewarded with breathtaking coastal views. The vast expanse of the Southern Ocean unfurls before you, meeting a beautiful white sand beach. Keep an eye out for the secluded beach with caves and large rocks, a perfect spot to relax and soak in the scenery after your hike. Remember, the beach may be scenic, but strong waves and rip currents make swimming dangerous.

About the region
Kangaroo Island's crown jewel, Flinders Chase National Park, offers a chance to explore a vast wilderness teeming with wildlife. Witness the otherworldly shapes of the Remarkable Rocks, their golden hues contrasting with the ever-changing ocean backdrop. Stand in awe at Admirals Arch, a natural wonder carved by relentless waves, and observe a colony of long-nosed fur seals basking on the shores below.
Entry fees are required, and while there's a Wi-Fi hotspot for payment at Rocky River, reception can be unreliable. For a smoother visit, consider purchasing your day pass beforehand. Park rangers are stationed within the park daily (9am-5pm) to answer your questions.
Be mindful of wildlife while driving, especially at dawn and dusk. Pack sufficient water and snacks, and adhere to leave-no-trace principles to ensure the park's continued health. Public toilets are limited, and there are no shops inside the park, so plan accordingly.
Flinders Chase National Park offers a unique experience year-round:
- Winter: Witness cascading rivers, diverse fungi, and blooming orchids.
- Spring: Experience an explosion of wildflowers, lively frogs, and breeding birds and animals. Spring and summer are perfect for camping, picnics, and exploring the many walking trails.
- Summer: Enjoy mild weather, ideal for swimming on pristine beaches. However, expect larger crowds during this peak season.
