Clay Pit SVRA

The clay here was excavated to build Oroville Dam, leaving a shallow basin ringed by low hills. California State Parks fenced it and opened it to motorcycles, ATVs, and 4x4s. Roughly three miles of informal tracks cross the 220 acres. There is no marked trail system. The fenced boundary is the limit, and riders set their own lines across the pit floor and up the surrounding rim.

Terrain and difficulty

The surface is compacted clay and dirt, and it behaves differently with moisture. Damp clay turns greasy and slick; dry hardpan goes firm and dusty. Elevation tops out around 150 feet, and nothing on the property is steep or technical. That makes Clay Pit a low-consequence place to start a new rider on a bike or quad, or to shake down a rig and confirm repairs before a longer trip. Riders after ledges, rock, or sustained climbs will exhaust it in an afternoon.

When to go

Fall is the most predictable window, once summer heat breaks and before winter rain saturates the clay. Summer days in Butte County run from the mid-80s into the low 100s, and the site carries little shade, so summer means early-morning riding. Winter and spring rain leave the clay slick and the basin prone to standing water. Check with the Northern Buttes District before a wet-season visit, because conditions can close the area.

Getting there

The riding area is about two miles west of downtown Oroville at 4900 Larkin Road. It is fenced, with a vehicle entrance sized for trailers. The nearest fuel, food, and lodging are in Oroville.

Registration, fees, and facilities

Entry is free. Every vehicle ridden here needs current California OHV registration, the green sticker, or an out-of-state equivalent. On-site facilities are limited to shade ramadas, picnic tables, and a vault toilet. There is no water on the property, so carry your own. The gate is open 8 a.m. to sunset, seven days a week.

The verdict

Clay Pit is a practical local riding area and a useful first outing or pre-trip shakedown, not a destination in its own right. Use it to log seat time or test a fix, then head east into the Sierra Nevada foothills when you want elevation and rock.
