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
