Castlecliff Beach is in for a post-summer clean up.
Whanganui District Council's youth committee has organised the event for this Saturday and will top it off with beach volleyball, prizes and a sausage sizzle.
Committee member Josie Verhaaren said they had wanted to organise an environmental focused event for a while.
"It's something that impacts us all and we think it's important," she said.
"A lot of Whanganui youth go to the beach over the summer and it's such a massive asset to Whanganui but there's a lot of rubbish left over; bottles, cans, chip packets. It's really not good."
