1. Pick Your Splash Zone
Start by choosing where your water fun will happen. You’ve got a few great options, depending on your budget and how much effort you want to put in.
Splash Pads
Perfect for low-stress parties! Most are free or super affordable and already set up for fun. Just bring towels, sunscreen, and some birthday treats.
Check out the best splash pads in the 903 area with a built-in map to help you find one nearby.
Public Pools
Want something more traditional? Many local pools offer open swim hours, shady picnic areas, and lifeguards on duty.

Rent a Private Pool
Want privacy without the prep? You can rent a private pool by the hour on Swimply, like Airbnb but for swimming!
Set Up Water Fun in Your Own Backyard
Don’t want to leave the house? You can throw a water party at home! Here are some easy, kid-approved ideas:
Slip n Slide
Sprinklers or splash pads
Kiddie pools with squirt guns
Water balloon games
Inflatable bounce house with a water slide
Mix and match to fit your space and your crowd. Even toddlers and grandparents can join in when you keep things simple and safe!
2. Plan Snacks & Seating
Water play works up an appetite! Keep the food kid-friendly and refreshing:
Watermelon slices
Grapes
Juice boxes or ice water
popsicles
icecream sandwhiches
Cupcakes or dirt cake; it was a hit at my son’s last party. Both kids and adults came back for 2nds.
Set up a shady rest zone for parents and littles who need a break. Blankets, lawn chairs, and umbrellas go a long way.
3. Add a Touch of Wow
Want to make the day feel extra special? Add one or two fun extras:
Balloon arch for a festive entrance
Foam machine for wild, bubbly fun
Cotton candy cart for sweet party vibes
