A Spectacular Sea Cave on Tasmania’s Rugged Coast

Remarkable Cave is one of the Tasman Peninsula’s most impressive natural attractions. A short walk from the car park leads to a dramatic viewing platform overlooking a sea cave carved by thousands of years of relentless Southern Ocean swells.

Despite its short length, this walk delivers some of the most spectacular coastal scenery in Tasmania. The surrounding sandstone cliffs, crashing waves and sweeping views across Maingon Bay make it an essential stop for anyone exploring Tasman National Park.

Walk Overview

Track Description

The walk begins at the Remarkable Cave car park, where a short sealed path leads to the Maingon Bay Lookout. This accessible viewpoint offers magnificent views across the rugged coastline and is suitable for visitors with limited mobility.

From the lookout, descend approximately 115 steps to the purpose-built viewing platform beneath the towering sandstone cliffs. From here you can safely admire the remarkable tunnel-shaped sea cave carved by centuries of wave action.

During periods of large ocean swell, waves surge dramatically through the cave, creating one of the most spectacular coastal displays on the Tasman Peninsula.

Difficulty

Although the walk is very short, it is rated Grade 3 because of the long staircase leading down to the viewing platform. Most visitors can comfortably complete the walk, but the return climb may be challenging for those with limited mobility or fitness. The upper lookout is accessible without using the stairs.

Walk Highlights

Remarkable Cave

The enormous sea cave has been sculpted by the Southern Ocean into a striking tunnel through the sandstone cliffs. Depending on the angle of the light, some visitors notice the cave resembles the outline of Tasmania.

Maingon Bay Lookout

Before descending the steps, enjoy sweeping views across Maingon Bay, Penguin Rocks and the rugged Tasman coastline from the elevated lookout platform.

Dramatic Coastal Scenery

Towering sandstone cliffs, pounding surf and spectacular ocean views combine to make this one of the most photographed locations on the Tasman Peninsula.
