Poison Spider OHV Park

Poison Spider Off-Road Vehicle Park is a 284-acre open OHV play area located on the site of a former bentonite mine near Casper. It allows visitors to explore just under 300 acres of terrain.

Use of the area is free to the public, but ATV stickers are required. There are limited picnic facilities and a vault toilet. For safety reasons, only motorized recreational uses are permitted in this park.


The BLM welcomes you to explore, enjoy, and make positive memories from your outdoor experiences on America's public lands and waters. Please remember these are wide-open spaces and wildlands. Plan ahead and be aware of potential hazards. It is everyone's responsibility to take the necessary steps to minimize chances of becoming lost or injured on public lands.

When visiting public lands, please also practice Leave No Trace and Tread Lightly principles.

For other key advice on various recreation activities, please see the BLM's trip-planning tips. These helpful tips can help you make the most of your recreation experience. However, for more information about local conditions, regulations and recreation resources, there is no substitute for visiting the closest BLM office.
