Tucked inside Palmetto Islands County Park in Mt. Pleasant, SC, Splash Island is a colorful water playground perfect for little toddler adventurers and elementary-aged kids alike. 

Our Favorites at Splash Island

My daughter loves the toddler area, there are enough activities in there to keep her busy all day. The small turtle water slide is one of her favorites, along with the interactive water “dams” where she can figure out exactly how she can get the water to overflow in all directions!

My son loves the otter slides and the swimming pool. The otter slides are great if you have multiple children because they can hold hands and go down at the same time, it makes for a sweet sibling photo op too! 

Note: While both of my children are too small for the body flume slide, it doesn’t put a damper on the day.

Cool Stuff to Play On at Splash Island

There are also lockers, restrooms, shower/changing spots, and a party area for birthdays! 

Extra Fun Outside the Water 

Splash Island is inside a big nature park — so families can also: 

• Bike or walk on miles of paved or wood trails 
• Picnics under shady trees 
• Visit the playground “Big Toy” area 
• Fish or crab off the tidal creek dock 
• Rent kayaks and paddle around (Just remember: the park’s bike rentals start at 10 am, and a $2 gate fee applies for entry) 

Tips for a Great Day at Splash Island

• Come early (right at opening) to grab a good lounge chair. We have come a few times and there were none available. Getting there early is key!

• Bring towels, sunscreen, and a change of clothes 
• Even after water time, explore the trails or the playground 
• Check if your birthday party could be here—Splash Island does private party rentals and birthday packages.
