MONTGOMERY COUNTY, Texas - Another venue at the Grand Texas Sports and Entertainment District in New Caney will open to the public for a sneak peek event.

The event will offer free admission to Gator Bayou Adventure Park from 10 a.m. to 6 p.m. Nov. 3. However, the maximum occupancy is 5,000 attendees, according to a post on the venue’s website.

Most of the park’s “adventures” will be free. The venue’s website lists a variety of activities, such as a fishing hole, a petting zoo, pony rides, bumper boats, a maze, zip lines, a free-fall attraction, a climbing wall and Wild Isle, a floating attraction with water slides, play features and challenge course activities.

Three adventures will be pay-to-play on Nov. 3: Big Rock Mining, where visitors use a sluice box to mine for rocks and gems; Eagle Challenge, a six-story structure with more than 50 activities; and Raccoon Run, an aerial adventure for kids ages 5-10.

There will also be food and vendors, according to the East Montgomery County Improvement District, which is hosting the event. If there is inclement weather, the sneak peek will be rescheduled.

Gator Bayou is adjacent to Big Rivers Waterpark.

The long-awaited venues were supposed to open on June 29, but the weather and other challenges delayed the opening, Grand Texas announced in July. A firm opening date was not set at the time, but the waterpark is expected to open in March 2019, according to the East Montgomery County Improvement District.

Grand Texas held a groundbreaking ceremony for the two parks last December after the project had already faced several delays. In March, the developer secured three USDA Rural Development Business & Industry loans totaling $20 million for the water park, adventure park and parking.

Both parks will be a total of 80 acres on the 630-acre venue and will include educational aspects to help guests learn about Texas rivers and wildlife.

The general contractor for the water and adventure parks is Huntsville, Texas-based Solid Bridge Construction LLC, and the architect is Sugar Land-based Van Horn Reed & Associates. Engineering and design work has been provided by Jacksonville, Florida-based WET Engineering; Houston-based Ward, Getz & Associates; Conroe-based Bleyl & Associates; and Minneapolis-based Quest Engineering.

Once Big Rivers debuts, the Grand Texas Theme Park and Grand Texas Sportsplex will begin their two-year construction process, Galland said previously. When finished, the theme park will have five roller coasters, dozens of rides and live entertainment. Plans for the entire project also include Grove Factory Outlets, four hotels, restaurants and a 24-hour urgent care center.

Other parts of the entertainment development, located at Highway 242 and Interstate 69, have already debuted. Grand Texas RV Resort opened in August 2016, and the SpeedSportz Racing Park held its soft opening in December 2016.

Grand Texas has faced significant delays since its master plan was first revealed in 2013. Some delays were due to a lender backing out, the energy downturn and construction delays on infrastructure projects surrounding the project.
