Review: Big Rivers Waterpark and Adventures brings big time fun to Greater East Montgomery County

The newest family destination is here to beat the summer heat and for those living in Greater East Montgomery County or northern Harris County, they won’t have to drive far to find it. Big Rivers Waterpark and Adventures is now open, and it brings with it a day filled with activities for all ages.


Opened in late-May, the crown jewel of the Grand Texas development years in the making is attracting large groups to the 80-acre park that features waterslides, a wave pool, lazy river, water obstacle course, petting zoo, a gator feature and more. Admission gets you into all the water attractions and many of the other activities. Certain ones, including the ropes course, zip lines, and others will cost extra.


The first thing we noticed as we walked up to the park entrance is the many colorful waterslides, namely the Colorado River Racer, six twisting slides several stories high. The bigger kids and adults will get into these as they twist and loop on their descent.



Located in the center of the park, Gator Splash is a huge splash pad that features eight slides. As my five-year-old will attest, this one is fun for everyone and the slides are just fast enough for older riders to enjoy. I really liked the massive bucket on top of the structure that dumped gallons of water below every five to 10 minutes.


Smallest waterpark visitors can experience Hatchling Hill, five tot slides that won’t be too much for toddlers to ride. The Polliwog Puddle is a smaller splash pad with sprinklers and water nozzles with room to splash and play.


We really enjoyed the Rio Grande lazy river, a tube ride attraction that winds through the middle of the park for about a quarter mile and offers a relaxing respite from the more thrilling rides.



Situated next to the lazy river is the Boca Chica Bay Wave Pool that produces tall waves that aren’t overpowering. To keep kids safe on either attraction, lifejackets are available at no cost, lining the fences of the wave pool.


Hidden in the forest, a short walk from the wave pool is Wild Isle, an intense water obstacle course situated on a small lake with 54 different elements that recalls an American Ninja Warrior course for Aquaman and his friends – this was a workout! Kids under four-feet-tall can’t do it alone but are allowed on with an adult if the grown-ups sign a waiver. Word to the wise though: if you don’t want to be pushing and lifting your small child up and down the course, it might be best to skip this one. For all others, Wild Isle is a can’t-miss attraction.


Want to take a break from the action? Big Rivers offers some quieter attractions on dry land, including the Mystic Forest Maze, which is harder than it looked. It took us around 20 minutes to find all the letters (M-A-Z-E, of course) and find the exit. 



Big Al’s Farm included baby chicks, baby pigs, and a petting zoo with goats and sheep. Don’t make the mistake we did and bring food ($3 a bag) into the enclosure as the goats will get a little too friendly. Pony rides are available for a fee, but the nice handler let us pet the pony at no cost. 


Big Al’s Fishing Hole, situated on the same lake as Wild Isle, offers fishing poles with affordable bait ($2) to try your luck in catching the big one. Gator Gulch allowed us to get up close and personal with real live alligators.



One massive feature at Big Rivers included several aerial challenges, including zip lines that crisscrossed the park and a tall ropes course. We didn’t get to try it out because we were too busy in the water, but it looked like it was worth the extra cost to strap in and climb.


Unfortunately, one set of slides, including the Comal Crush and Storm Surge attractions, had yet to be open when we were there, but we checked back in and the park is now 100 percent open. This area consists of several rides, including one that ricochets tubes up the side of two angled walls, sure to be one of the most sought-after attractions in the park.

A few things to know before you head to the park: food and beverages aren’t allowed in, so be sure to bring some extra money for the food vendors, including two food trucks and Big Red’s BBQ restaurant. Lockers are also offered and cost $10 a day for small ones. Parking is free, but it’s a bit of a walk from the free lot to the entrance, so have some decent walking shoes to wear into the park and when you leave.



The best part is Big Rivers is now running a special Monday through Thursday with admission 55 percent off its regular price, making it a great excuse to take the day off and enjoy some fun in the sun. Head to the park website for various specials throughout the summer.


Overall, this was a great way to spend a hot summer day and one that the entire family will enjoy. Being its inaugural year, the lines are very short to get on all the rides, so be sure to visit before everyone else discovers it. And always wear sunscreen.
