The Main OHV area is closed seasonally from April 9 through November 1 to help minimize disturbance to wildlife and cattle, while also reducing soil erosion. Regulations and a map of the area are available online at www.fs.fed.us/r2/arnf/recreation/ohv/png/index.shtml. 
The Crow Valley Campground is now available to those exploring the grassland. This is the only developed campground on the PNG and is located on Weld County Road 77.
