Summer’s not even officially here yet, and the temps are already soaring. Before it gets too late, you’re going to want to make sure you’re ready for the hottest days ahead. And what better way to keep the kids cool than by bringing home Costco’s giant, new backyard water slide before it’s gone?

The Happy Hop Dinosaur Cave Adventure is an inflatable that features an enclosed cave slide shaped like a T. rex—perfect for the Jurassic Park enthusiasts in the house—a fun climbing wall, and a pool area where kids (ages 3+) can play and splash. It’s 216.5" x 153.5" x 151.6", and it weighs 71 pounds. While large, it comes with a constant flow electric blower said to inflate it entirely in one minute, according to the site.

Additionally, it comes with eight ground stakes to secure it to the ground, a repair kit in case all the fun results in any damage, a water jet with hose connection, and a large bag for easy storage during the colder months.

Reviewers on Costco’s website are calling it “totally epic” and say their kids can’t get enough of it. “Love it! Worth every penny! We are going to put it to good use! These are good quality and super easy to install!” one said.

“This has been such a great purchase. It’s the perfect size for our backyard, and my kids have hours of fun on it,” said another.

You can only purchase this specific water park if you have a Costco membership. And coming in at $430, it’s a bit pricey. However, if you’re not ready to fully commit to the membership, we’ve found similar water parks on Amazon you can check out (they’re also cheaper).
