Hundreds of locals and visitors enjoy bushwalking and swimming at Mermaids Pools but they are tainting the area by leaving rubbish.
Lakesland resident Naomi Murrin said she had noticed an increase in discarded take away containers and picnic plates.
She is encouraging everyone who visits the spot to not only take away their own rubbish but to collect an extra bag of rubbish to keep the area beautiful for all.
“Everyone has a personal responsibility to keep the pools looking beautiful,” she said. “I know carting empty food rubbish back to the car is undesirable but it is appalling that people leave their rubbish behind because of laziness.
“Locals should have pride in the beautiful natural spot we have been blessed with and I want to be enjoying the pools for a lot longer.”
Mrs Murrin said her family of eight would make an effort to visit the site regularly to collect bags of rubbish.
She said any tourism material about the pools should have a note saying there are no bins available.
Infrastructure and environment director Michael Malone said Wollondilly Council didn’t provide maintenance because the pools were in a natural reserve.
“The council does not install rubbish bins as they cannot be serviced appropriately,” he said. “If bushwalkers are going there then we encourage them to take only photos and leave only footprints.”
