OHV Park Closure Alert Page and OHV Park Pages

The DNR OHV Program has recently made some changes to the program pages on the web site and with the OHV Reference Guide to make finding OHV-related information easier for enthusiasts. 

To find information about OHV rules, regulations, grants, ATV Education, riding in Iowa, and more, go to

A page for each park has been added to the web site to provide riders with information about location, trails, and amenities.  This information can be found at  Want to see yourself on the DNR web site?  Send your pictures, videos, and your favorite things about your favorite park to  Remember to showcase your personal protective equipment, registered vehicles, and good stewardship practices in addition to your riding skills.

From time to time the OHV parks need to be closed due to wet weather, trail projects, or special events.  A new OHV Park Closure Alert System has been implemented to provide you with up-to-date closure information.  A listing of park closures can be found by going to the link for the parks and opening the menu in the left-hand navigation pane (click on the plus sign).  Each park manager can post real-time closure information about the park.  This is the best tool we have to let riders know about a park's status of closed.  The OHV Park Hotline has been discontinued.

Additionally, the 2014 OHV Reference Guide has QR codes for each park's page and the park closure page for enthusiast convenience.  These codes can be found on pages 26-33.

Special Events Calendar

When individuals and groups want to use public land and water for events, they must apply for use of that resource through the Iowa Department of Natural Resources.  These events are compiled by the Special Events System and are displayed on a calendar of events.  These events can be searched by type, location, and date.

Special Event Permits

The Iowa DNR is authorized to approve a club or individual to hold an organized special event (an organized race, exhibition, or demonstration of limited duration which is conducted according to a prearranged schedule and in which general public interest is manifested) within the state if the event is scheduled to be held on public land or public ice.
