About the Recreation Area

This 137-acre recreation area is located in North Dubuque. The unique beauty of the Driftless region of Iowa is very evident here with the following natural beauties:
  • Limestone rock outcroppings
  • Panoramic scenery
  • Restored prairies
  • Upland timber
  • Wildlife

John Deere Donated the Property

In 2018, John Deere Dubuque Works donated the property to the Dubuque County Conservation Board. The name Proving Grounds was selected for this area because previously John Deere used the grounds to test and prove out the quality of their machines and products. Also, the name was selected because when it comes to outdoor recreation, people often are trying to challenge themselves, establish mental and physical goals, and ultimately prove it to themselves that they can do what they set out to do.


This area offers hiking trails, picnic areas under the pavilion, and mountain bike/multi use trails. Hunting is allowed during archery season.
