The park came to existence in 2018 from land donated by John Deere. The area was the original proving grounds (testing area) established for John Deere Dubuque Works. It has been transformed into a premier mountain biking destination. Enjoy a wide range of double track hiking and mountain bike paths throughout the park. Intermediate to advanced single track trails provide every rider with a unique riding experience. Beautiful vistas, swift timber runs, and vertical jumps make this a go to for all skill levels.
