ZDT's Amusement Park in Seguin, Texas, is set to permanently close down on Sunday, August 17, after a nearly 20-year run.

The family owned and operated park is home to Switchback, which opened in 2015 as the world's steepest wooden coaster, designed by The Gravity Group and built by Gravitykraft Corporation.

Other popular attractions include the Thundervolt Speedway, Dizzy Toucan and Parachute Drop.

Statement from ZDT's Amusement Park:

We are so honored to have provided smiles, thrills, and happy memories for 18+ years! After much consideration, we have made the difficult decision to close our park. Our last operating day will be August 17, 2025. We sincerely appreciate all your support  over the years. It has been really fun and heart-warming being a part of your story! We hope you will come out for one last visit!

We had the pleasure of visiting ZDT's Amusement Park in 2023 as part of our Texas Twist tour.

A Brief History of ZDT’s Amusement Park

ZDT’s Amusement Park, located in Seguin, Texas, is a 10-acre family amusement park that opened to the public in March 2007. Founded by Danny and Sarah Donhauser, the park was named after their three children—Zac, Danielle, and Tiffany—using the first letter of each of their names. Originally launching with five indoor attractions, ZDT’s quickly expanded, adding multi-level go-karts in 2008 and its first water ride, the Mad Raft Water Coaster, in 2011.

In 2015, the park made national headlines with the debut of Switchback, a groundbreaking wooden shuttle coaster designed by The Gravity Group. Featuring an 87-degree incline and a 104-degree overbanked turn, Switchback was the first and only wooden coaster of its kind, named in honor of the 1884 Switchback Railway, considered the first roller coaster in the United States. The ride was carefully integrated into the park's historic setting, weaving through existing buildings and culminating in the dramatic "Grand Spike."

ZDT’s was uniquely built on a property with rich agricultural and industrial roots. Instead of demolishing existing structures, the Donhausers preserved and repurposed them—grain silos became climbing walls, warehouses were turned into go-kart tracks, and the original Santa Fe train tracks were transformed into pathways. An executive train car still sits on the grounds as a tribute to this legacy.

Open year-round (with water rides operating seasonally from March through September), ZDT’s has offered a mix of 12 attractions and a classic video game arcade. After 18 years of operation, the park is set to close its doors permanently on August 17, 2025, marking the end of a uniquely Texan amusement experience rooted in family, innovation, and history.
