In the seven months that Jumpoline Park has been open, the trampoline playland has steadily increased its customer base through parties and a weekly disco night. On 100-degree-plus temperature days and recent cold spells, manager Brian Kelly said the place is packed.

"People just come for the exercise," he said.

The Roh family opened Jumpoline Park in Northwest Austin in July, and in December, followed with a second location on I-35 in South Austin.

Admission is $10 for the first hour for patrons age 5 and older and $7 for children younger than 5. Each additional hour costs $5.

Jumpoline Park also hosts a weekly disco night on Friday from 7–11 p.m. that is geared toward teenagers. Admission is $10 for the four hours.
