Oh, summer! The sun is shining, the birds are singing, and the heat just keeps climbing, making a refreshing splash the only thing on everyone’s mind. But what if cooling off could be even more fun? Imagine beating the heat while having a blast with friends or family, the ultimate way to make those hot days unforgettable.
Around the city, water parks offer great escapes, but none compare to the biggest inflatable aqua park in Southern California, floating right on the county’s largest man-made lake. That’s Cali Splash Park, where the shimmering waters of Castaic Lake become a giant playground for thrill-seekers of all ages!
At Cali Splash, adventurers can tackle over 45 obstacles, from slides and wobble bridges to trampolines and climbing walls, all designed to test balance and bravery. It’s a unique experience that’s as challenging as it is exciting.
To make the most of it, the park runs sessions every two hours from Wednesday through Sunday. Visitors can grab a two-hour session pass or go all-in with a full-day ticket. This setup lets everyone find their perfect pace, whether they want a quick splash or a whole day of fun.
And if you’re bringing kids who prefer a bit less action, Castaic Lake has plenty to offer beyond the inflatables: kayak and boat rentals, picnic spots, barbecue areas, and a calm swimming beach, making it a perfect day out for the whole family.
⏰ Hours: Wednesday through Sunday, 10AM-6PM, until September 28, 2025.
