"Every time we've gone down to the beach it's been different, very changeable and very cute with the park there as well.
"I can imagine it would get quite rugged if the weather wasn't so nice."
Across the grass, Whanganui local Maria Larking was parked up in front of a fan, enjoying some reggae.
She said there had been a large family gathering at "The Bach" for Christmas.
"We've had this spot for about six years, and we're here every summer.
"It started with the caravan, then we put on the annex, then we got the deck.
"We were down at the beach fishing at 6.30 this morning. The sunrise was just magnificent."
Downpours of rain hadn't dampened spirits during the two-week stay, Larking said.
"That's the time for board games, then when the rain settles, the kids are back out again splashing around.
"You've got to make the most of your time out here."
Jo Manson from Levin was enjoying the shade with friends and family.
Like the Smyths, it was her first time camping at Kai Iwi.
"You're allowed to bring your dogs too, which is great," Manson said.
"They had a hard day at the beach yesterday, and they will have another one later on."
The grass at Kai Iwi was a welcome change, she said.
"We've got a bit sick of camping on sand."
The Somerville family were in Whanganui from Christchurch to visit family.
The flying fox was the number one reason for their visit to Kai Iwi, Wendy Somerville said.
"We definitely don't have one [in Christchurch] that goes over a creek," she said.
"The whole playground here is great, we're really impressed."
