Visitors can wander through 1.25 miles of trails cut in the 7-foot-tall restored prairie grasses.
Maze walkers should park at the west lot at the northwest corner of Worster Lake. Maps of the maze will be available at the park entrance gate, park office and the nature center through the end of October.
The maze is free. Admission to the park costs $5 per in-state vehicle or $7 per out-of-state vehicle.
