When Is the Best Time
Remarkable Cave, located near Port Arthur on Tasmania’s rugged southeast coast, is a natural sea cave with two ocean-facing entrances and one inland exit. This dramatic tunnel was shaped over millennia by tectonic activity and relentless wave erosion, especially during high tide when powerful southwesterly swells crash into the cave.
The cave’s structure is constantly evolving, carved by the force of the sea and wind. At low tide, adventurous visitors can access a hidden beach through the cave — a rare and unforgettable experience. Important: Always check tide times for Remarkable Cave before visiting, as access is only safe during low tide.

Tide Times Matter

Location and Tips
The short five minutes trail starts at the Maingon Bay Lookout. The view of Cape Raoul from here is terrific. After a short walk, steep steps lead to a viewing platform.
If you want to enter the cave, you must climb over the handrail to the beach. We saw several footprints, and it was low tide. We were too curious not to go—the tunnel cave branches in two entrances heading out to the sea. 
Straight ahead, the cave is shaped like Tasmania and leads to the hidden beach. Local surfers love this spot if the conditions are right. 
Above the platform was a part of the cave’s roof, which collapsed long ago. Why remarkable? Sometimes special effects in rocks get created by intense heat, earthquakes, and pressure. The beautiful sandstone and dolerite folded patterns are rare and remarkable. It is best seen on the outside wall of the cave. 
On a clear day, you are able to see Cape Raoul in the distance. My top tip for an exceptional day hike nearby.
