Trowutta Arch, Tasmania - A Hidden Geological Wonder along the Tarkine Drive

Tucked away in the Trowutta Caves State Reserve along the scenic Tarkine Drive, Trowutta Arch is one of Tasmania’s most intriguing natural landmarks. This remarkable formation was created when ancient caves collapsed, leaving behind a large, naturally sculpted rock arch that feels both dramatic and mysterious.

Surrounded by lush rainforest and cool-climate forest, Trowutta Arch offers a quiet, almost otherworldly experience — a place where geology, nature, and tranquillity come together beautifully.

A Landscape Shaped by Collapse and Time

On either side of Trowutta Arch are two striking ground depressions known as dolines. One is a dry, fern-filled hollow, carpeted with moss and shaded by native trees. The other is a deep, water-filled sinkhole — known scientifically as a cenote — with steep sides and an eerie, green-hued pool that drops to a depth of around 20 metres.

These contrasting features provide a fascinating insight into the dynamic geological processes that have shaped this part of Tasmania over thousands of years. The Trowutta Caves State Reserve, covering 66 hectares, has been protected since 1976, ensuring the preservation of these unique and spectacular formations for future generations.

Trowutta Arch Walk

Distance: Short walk - Time: Approximately 15 minutes - Grade: Easy

A short, well-formed path leads through cool-climate rainforest to Trowutta Arch, making this an easy and accessible walk for most visitors.

The walk itself is a highlight. Towering blackwood and myrtle trees rise overhead, while fragrant sassafras and majestic man ferns create a lush, enclosed feel. Fallen logs and branches are draped in thick, vibrant moss, giving the forest a timeless, ancient atmosphere.

Reaching the Arch

As you approach Trowutta Arch, the scale and beauty of this natural structure become clear. The arch is large enough to walk through, and its sheltered setting makes it a wonderful place to pause, sit quietly, and take in the surroundings.

Whether you’re admiring the dramatic rock formations, listening to the subtle sounds of the forest, or simply enjoying the peaceful isolation, this short walk delivers a surprisingly powerful experience.

The unsealed roads are generally suitable for 2WD vehicles, though it’s best to take care after rain.
