Shack communities of the Royal National Park will welcome visitors on Sunday, April 13.
Walkers are invited to visit Little Garie, a 15-minute walk along the cliff line from Garie beach or to go to Burning Palms or Era, a steep two-kilometre walk down the escarpment.
There will be several open shacks so visitors can peep inside and hear about life away from all the mod cons of 21st century life.
Visitors will be able to have a sausage sizzle and a cuppa made from tank water heated on a kerosene stove.
The communities were built originally on freehold land that was a grazing lease. Shack owners lobbied against its sale before it was incorporated into the Royal National Park in 1953.
National Parks and Wildlife Service demolished 50 shacks in the 1970s and 1980s and in 1993 the National Trust recognised their heritage value and stopped the demolition.
