Pedal or shuttle up the forest service roads, same as if you were doing Hardesty Trail #3469. There's a short singletrack climb to the top (tough if you already pedaled up).
About 0.5 miles from the top, take a hard right instead of continuing on Hardesty Trail #3469. The top half gets kind of steep, with some loose rocks and small drops for good measure. After that, let go of those brakes! The bottom half flows nicely with some tighter switchbacks mixed in. The trail ends at the South Willamette Trail.
