Barnard Pipeline Road follows a gas pipeline over 21 miles from Alamo Road across the Buckskin Mountains to the Bill Williams River. The initial third of the trail is unremarkable along Butler Valley's saguaro and ocotillo-studded flat land. The trail passes a large pipeline facility a few miles in.
After crossing Cunningham Wash, the trail gets far more interesting. The semi-maintained trail climbs steadily into the mountains, reaching gradients of 16 degrees. Two bypasses help with the steepest sections, but only slightly. The mountain views are exceptional. The descent provides a long look ahead.
The final third of the trail is a seemingly never-ending series of deep wash crossings, many quite steep. 4WD is required, and low range helps with the steepest grades. The trail ends at the Bill Williams River. The pipeline is elevated across the river. Numerous ATV trails lead down to the river.
Only one established campsite near the river was located along the trail. It is suitable for up to 3 vehicles, has a fire ring, and nice views.
