Dentrecasteaux National Park

Dentrecasteaux National Park is a wild, windswept stretch of Western Australia's south coast, where the Southern Ocean crashes against dramatic limestone cliffs and ancient karst formations. Named after the French explorer Bruni d'Entrecasteaux, this park offers a raw, untamed beauty that feels a world away from the tourist trail. Here, you can walk among towering karri and jarrah forests, explore eerie limestone caves, and stand atop rugged headlands watching for whales and seabirds. It's a place for those who love solitude, coastal walks, and the powerful rhythms of nature.

Highlights & What to See

• Canal Rocks: A series of granite boulders forming a natural breakwater, with waves crashing through channels – perfect for coastal photography and spotting dolphins.
• Yallingup Caves: Explore underground marvels like Ngilgi Cave, with its stunning stalactites and Aboriginal Dreamtime stories.
• Cape Naturaliste Lighthouse: Climb this historic lighthouse for panoramic views over Geographe Bay and the surrounding national park.
• Boranup Karri Forest: Drive or cycle through towering karri trees, some over 60 metres tall, with walking trails that weave among the giants.
• Whale Watching: From June to December, humpback and southern right whales migrate past the coast – head to the Cape Naturaliste lookout for prime views.

Suggested Time to Spend

To fully appreciate Dentrecasteaux National Park, plan for at least a full day – ideally two if you want to hike several trails and explore the caves. A single day allows you to drive the scenic loop, stop at Canal Rocks and Cape Naturaliste, and visit one cave. With two days, you can add a longer walk like the Cape to Cape Track section between Cape Naturaliste and Sugarloaf Rock, and explore the Boranup Forest in depth. The park is compact enough for a relaxed self-drive itinerary, but the best experiences come from slowing down.
