Building a themed sandcastle, digging for prizes and learning some safety tips are just some of the activities on offer at the Kai Iwi Beach Dig.
The community fun day on Sunday, March 3, is being organised by the Whanganui Lifeguard Service and Mitre 10 Mega Wanganui.
Paula Fore, Mitre 10 MEGA's marketing, events and promotions co-ordinator, said the event would highlight water safety and support the lifeguard service.
"In 2017 we helped build the guard tower at Kai Iwi Beach," Fore said.
"We want to keep awareness going of the dangers of the surf. People don't realise how dangerous it is at Kai Iwi Beach."
