This reserve is just south of Mt Field National Park, a one-hour drive north-west of Hobart, near the township of Tyenna. Marriotts Falls offers a moderate short walk suitable for most fitness levels. A signposted turnoff just outside the township takes you to the Marriotts Falls walking track beside the Tyenna River.
The walk passes through groves of tree ferns and immense swamp gums, the tallest flowering plants on earth. The total return distance to Marriotts Falls is around five kilometres.
A short drive further south from Tyenna is the Junee Cave State Reserve, five kilometres west of the township of Maydena. A short nature trail leads to the entrance of the cave where the Junee River rises to the surface after travelling 30 kilometres underground through a system of almost 300 caves.
Interpretive signs describe the Junee cave system, which includes Niggly Cave, Australia's deepest cave.
