Sisters Beach is a compact settlement between a broad Bass Strait beach and the eastern end of pinmatik / Rocky Cape National Park. It is a residential place with direct walking access to protected coastal heath, not a resort town with extensive services.
Begin at the beach and boat-ramp end
The beach is open to Bass Strait weather, and its apparent shelter changes with wind and swell. Swim only after assessing current conditions, keep clear of boat launching activity and avoid disturbing shorebirds on the sand.
Banksia Grove is the short park walk
The Banksia Grove and Caves Circuit begins near the Sisters Beach boat ramp and takes up to an hour for about 1.6 kilometres. It climbs through saw banksia heath before reaching viewing points above Aboriginal cultural sites.
Platforms protect midden material and other evidence of thousands of years of Aboriginal occupation. Stay on the track and platforms, and do not enter the caves.
Postmans Track needs a return plan
Postmans Track is 2.1 kilometres one way. Parks Tasmania estimates about an hour one way or two-and-a-half hours return when combined with the beach. A two-car arrangement can shorten the outing, but parking must not obstruct residents, boat users or emergency access.
Longer inland and coastal routes connect Sisters Beach with the western side of the national park. They cross steeper and rougher country and need a car shuttle or pickup plan.
Clean soil from footwear when leaving because Phytophthora is present in the national park. Drive slowly on the unfenced access road, especially around dawn and dusk. Boat Harbour Beach and Wynyard provide nearby services and a different style of coastal stop.
