A major Arlington waterpark is undertaking a big expansion: Hurricane Harbor Arlington, which calls itself the largest water park in North Texas, is adding a massive new water play structure with slides and surprise features, set to open in 2025.

The park is also introducing guest amenities including a coastal-themed area with vividly-colored slides and a multi-level interactive play structure. There'll be more activities for children, plus updated dining options, family cabanas, and refurbished restrooms.

Located at 1800 E. Lamar Blvd. in Arlington, Six Flags Hurricane Harbor Arlington is the watery cousin of Six Flags Over Texas, the longtime theme park in Arlington; the two facilities are just across from each other on opposite sides of I-30.

Hurricane Harbor features more than 40 rides and attractions like Typhoon Twister and Tsunami Surge. But in the competitive world of waterparks, it's never enough, you need more more more.

The expansion includes:

• Splash Island: A 58,000-square-foot area with a multi-level water play structure, more than 110 water features, seven kid-friendly water slides, and various water gadgets. A 1,000-gallon Texas-sized tipping water bucket will add to the fun, soaking splash-seekers below.
• Kids Water Slide Area: Seven additional water slides for smaller riders, including a mini-tornado water slide and a mini wave slide. They have names: Cowabunga, Jellyfish Twist (two slides), RipQurl, Shark Attack, Splashin’ Seal, and Stingray Racer — designed to brings the perfect number of drops and twists for little ones seeking a gentle thrill.
• Splash Pad: with 24 water features

Other amenities include the option to rent new family cabanas and oversized umbrellas. Junior guest-friendly furniture will also be available, and restrooms in the area will be refurbished.

Enhanced dining options will include the renovation of the in-house restaurant.

In a statement, Six Flags Over Texas and Hurricane Harbor park president Richard Douaihy calls it a "historic expansion" that will represent a new experience, which attendees can enjoy in an unlimited manner if they buy a season pass to both facilities.

"We are transforming the water park with exciting new family attractions and enhanced comfort and dining options, making it the premier destination for family waterpark fun in North Texas," Douaihy says.
