GRAB your swimmers and get ready to jump into the Gympie Memorial Pool to celebrate its last season open before the aquatic centre unlocks its doors.

Manager Jeff Manthey said the transition was bittersweet, and an unfortunate reality of time marching on.

"My son, his whole life he's been at this pool,” he said.

Having worked at the pool for 21 years, Mr Manthey said it had been the site of a lot of fun for Gympie families - a trend which he has been delighted to see continue over the years, when people who had jumped in as young children now brought their own families along.

"It's fascinating when you see them turn up and they've got kids themselves now,” he said.

While the number of people through the gates in any season has dropped over the years, Mr Manthey said, the pool has seen increased usage by some demographics.

"A lot more of the older people are starting to use it.”

While there has been no official confirmation of the pool's final date, he said he was certain people could expect it to be open until at least February.

"We may get a full season here which would be to the end of April,” he said.

The pool will be open from 7am-6pm weekdays.

From the end of the holidays, weekday hours will change to 5am-6pm and 8.30am-5.30pm on weekends.

Entry costs $3.50 for adults and $2.50 for children.

It will be closed on Christmas Day.
