Remarkable Cave from the viewing platform

Details

Remarkable Cave is a walk in the Tasman National Park.

15 minutes return. Grade 3.

Enjoy the vista from Maignon Bay Lookout of the rugged southern coastline before descending the steps to the spectacular Remarkable Cave.

From the car park it’s a short, accessible walk to the large viewing platform where you will find exceptional views of Penguin Rocks and the bay with Cape Raoul in the distance. Wild waves pound away at the coastal rock below to create this dramatic coastline. From the central carpark, descend the 115 steps to view the aptly named Remarkable Cave. You’ll be surrounded by steep, ancient sandstone cliffs​ and view the cave from the custom-designed platform at the base.

The tunnel-shaped cave was formed through years of torment from crashing waves, eventually causing a wall of the sandstone cave to collapse and create the tunnel that stands today. Some of the collapsed rock from the cave can still be seen at the base of the cliffs. At certain times of year, the waves rush through the tunnel creating a thrilling spectacle for those lucky enough to witness it. Be prepared to get a little wet!

Please refer to the Parks and Wildlife Service Tasmania website (parks.tas.gov.au) for up-to-date information about this walk, alerts, closures, safe walking guidelines, leave no trace principles and National Park entry fees where applicable.
