Big Thank You to the Atlantic Iowa Lion's Club for the cabana area overhaul! Give them a big shout out in the comments for us and let our community know how thankful you are that they invest in the betterment of the pool ❤️
We have been so blessed by some great donations this year, we cant wait to keep recognizing all the new at the pool.
If you missed our past post, these Cabanas are now available to be reserved! You can do one side or the whole area for a daytime party. Daytime parties are available every day of the week during open pool hours.

ATLANTIC – The Atlantic Lions Club donated $2,500 to the Sunnyside Pool to improve an area at the pool, and turn it into a resort style seating area.
