Tyenna: Karst Spring, Caves and River Landscape

Natural attractions around Tyenna include karst, caves and the Tyenna River. Marriotts Falls State Reserve protects important landscape and natural values. When choosing your destination, you can consider whether you would like to focus mainly on cave landscapes, a walk or fishing opportunities. These priorities also provide a practical guide when looking for a hotel for your stay in Tyenna.

Karst and Caves at Junee Cave

A significant karst spring at Junee Cave lies in the Tyenna River catchment near Mount Field National Park. It is fed by up to 80 underground tributaries. Junee Cave State Reserve is a short drive south of Tyenna and five kilometres west of the town of Maydena. The Junee River emerges at the cave entrance, which can be reached via a short nature trail.

The river reaches the surface after travelling 30 kilometres underground through a system of almost 300 caves. The area is also remarkable below ground: the Junee Cave aquifer is among Australia’s most extensive and hydrologically complex karst systems. Interpretive signs explain the cave system, which includes Niggly Cave, considered Australia’s deepest cave. Here, the visible river at the cave entrance and an extensive underground system are both highlights.

Walk to Marriotts Falls

A signposted turnoff just outside Tyenna leads to the walking track to Marriotts Falls. The nearby walk is described as short and moderately challenging, and suitable for most fitness levels. The total return distance is about five kilometres. The track passes through groves of tree ferns and mighty swamp gums, the tallest flowering plants on Earth.

A 2002 management plan describes a route through a river reserve on the Tyenna River, across two private properties, and then through another river reserve on Marriotts Creek to the reserve. As track conditions can change, check conditions and local signage before setting out.

River Landscapes and Fishing

The Tyenna River is a large, fast-flowing river in the nearby area and offers opportunities for all types of fishing. It is managed as a wild trout fishery dominated by brown trout, while also having a reputation as a rainbow trout fishery. Large populations of small to medium-sized brown and rainbow trout offer another point of interest for anglers. Fishing conditions vary seasonally. River conditions and access can also vary depending on rainfall and land access.

These natural attractions also differ in how you might plan your visit: at Junee Cave, a short nature trail leads to the cave entrance, while the walk to Marriotts Falls covers an approximate return distance of five kilometres. The river, by contrast, offers an opportunity to explore the destination from a fishing perspective. You can choose Tyenna based on the focus that best suits your trip.
