A cooperative agreement between Central Oregon's Combined Off Highway Vehicle Operations (COHVOPS) and the Deschutes County 4-Wheelers of Bend Oregon made this play area a reality in 2006. Complete with a rock crawling pit and large gravel mounds which are remnants of the old rock quarry; this play area has something for every OHV enthusiast.
In addition to all this, Groundhog also makes for a convenient staging area for accessing 318 miles of trails on the East Fort Rock OHV Trail System. The pit and play area is open to all classes of vehicles, the trail system is open to Class I (Quads, 3-wheelers less than 50" wide and 800 pounds) and Class III (motorcycles).
