Step inside a breathtaking cave beneath the Boranup karri forest of Margaret River.
Venture down a dramatic sinkhole known as a doline, to enter this spectacular cave, where active crystal formations hang above a perfectly reflective underground lake.
What can I expect?
Join a fully guided one-hour tour beneath the Boranup Forest, beginning your journey with a descent into a natural sinkhole. From here, you follow a staircase weaving through sunken forest, before entering the pristine cave chamber below.
Inside the cave, your friendly guide reveals the delicate formations that make Lake Cave so awe-inspiring. Carefully placed lighting highlights shimmering stalactites, crystal decorations, and the famous ‘suspended table’ formation, a rare multi-tonne structure that appears to hover above the still waters of the underground lake.
- Pack a water bottle, but no other food or drinks are allowed inside the cave.
- Please wear comfortable shoes and clothing suitable for walking stairs.
- The caves are delicate and fragile. For conservation and safety reasons, we encourage you to limit the items you bring inside. Please leave backpacks in the car.
- Front-worn baby carriers are great for adventures but backpack baby carriers are not permitted.
- A reasonable level of fitness is required to join the cave tour.
- There are 325 stairs. Your guide will pause at landings along the way to share facts and stories, giving you plenty of time to catch your breath.

Each of the Margaret River Region’s show caves offers something different. Lake Cave is the only show cave in the South West with a permanent underground lake, and home to the remarkable ‘suspended table’ formation, a one-of-a-kind structure weighing over five tonnes that appears to hover above the cave’s reflective waters.
It is also the most active “dripping” cave in Western Australia, where droplets fall from delicate formations, creating ripples across the lake’s mirror-like surface.
Our Jewel Cave and Lake Cave experiences are fully guided. A visit to Ngilgi Cave is self-guided, and Mammoth Cave is audio-guided.

About Lake Cave
Stalagmites, stalactites, underground streams and sunken forests, some of the Margaret River Region’s most compelling landscapes, lie just beneath the surface.
Explore our cave guide to discover which underground experience is right for you.
Lake Cave is located within the Leeuwin-Naturaliste Ridge, a limestone formation approximately 90 kilometres long and 3 kilometres wide.
Formed over the past million years, the ridge is made primarily of Aeolian calcarenite—a type of limestone that began as coastal sand dunes, seashells, and coral, blown inland by strong westerly winds and gradually cemented by rainwater. Today, this landscape of limestone has been shaped by water and time into dramatic ridges, cliffs, and the caves we explore.
Inside the caves, you’ll find intricate natural features known as speleothems (pronounced spe-leo-thems). These formations include straws, stalactites, stalagmites, columns, shawls, helictites, and flowstone. All speleothems are made from calcite, a crystalline form of calcium carbonate.
As rainwater seeps through the limestone, it dissolves small amounts of calcium carbonate. When this mineral-rich water enters a cave, it begins to deposit calcite crystals, slowly building the stunning decorations that line the cave walls and ceilings today.
