Even though it's not open yet, the Big Rivers Waterpark & Adventures at Grand Texas promises to be the boldest and bravest of water park experiences. The wildly anticipated park will open on Saturday, May 25.

Hidden within northeast Houston’s tall evergreen pines and located within the Grand Texas 632-acre entertainment, dining, and shopping destination, Big Rivers is the city’s only 80-acre spot for water and adventure.

This place has more than 50 water and dry adventures. Expect water park attractions including Houston’s biggest lazy river, named the Rio GRAND River, that winds and curves more than a half mile. There's also Gator Splash, Texas’ largest interactive play structure, which is home to more than 300 water play elements, slides, and sprayers — and a Texas-sized, large bucket that dumps gallons of water onto playscape families below.

Fans can splash into the Boca Chica Bay Wave Pool, which produces the "tallest waves in Houston" and has a gradual slope from shallow to deep; the Comal Crush, a speedy raft ride with surprise drops and twisting turns; the seven-stories high, Pecos Plunge body slide; and Polliwog Puddle, a splash pad for the little ones, which has a special flooring and features light-pressure sprinkler water activities.

Families can also ride on Wild Isle, the state's largest inflatable obstacle (and the nation’s second largest inflatable obstacle). This floating obstacle complex on the park’s spring-fed lake contains 54 inflatable challenges.

For those who don't want to get wet, there are three different levels of zip lines for young children and adults that span throughout the park, giving families the ability to fly through the trees and over attractions. The six-story Eagle Challenge is home to 50 different zip and climbing activities and is ready to test any patron seeking a challenge.

Other activities include nature trails to view the park’s natural beauty and wildlife; a 70-foot climbing and free-fall tower named Vulture’s Dive; a petting zoo featuring more than 30 animals; a Mystic Forest maze to race friends and family; pony rides at the Pony Express; an interactive gator habitat; catch-and-release fishing at Big Al’s Fishing Hole; and Big Rock Mining, where guests can discover hidden treasures through a sluice box and more.

Big Rivers also offers up food and entertainment. Big Red's BBQ full-service restaurant features traditional, Texas barbecue favorites with indoor and outdoor seating, while The Dragonfly Biergarten has local craft beer and shaded seating. And, coming soon, an amphitheater will be able to hold up to 4,000 guests and will be home to many concerts and events year-round.

"My greatest experiences in life have been spending time and doing fun things with my family," said Big Rivers CEO/co-founder Monty Galland in a press release. "I wanted to create a local and unique destination for families that is unlike any other experience in Houston. The natural and serene beauty combined with the spacious grounds and number of activities that you can’t find elsewhere will be a big draw for families. Big Rivers Waterpark & Adventures is an opportunity to escape the hustle and bustle of everyday life, and to have fun making memories together in a beautiful setting.”
