Early settlers who accessed the pack trail along the Luckiamute River had difficulty connecting with Corvallis, the county seat. In response, the county surveyed "County Road 10" -- from Wren to Corvallis -- in 1854. The road carried supplies and troops to and from the riverfront at Corvallis between 1856 and 1865, when Fort Hoskins was manned, first with regular U.S. Army troops, then during the Civil War with volunteers from California and Oregon. Although for most of its distance Cardwell Hill Road is unimproved and not accessible to vehicles, it is dedicated public right-of-way and used as a service road today. Plenty of room to hike as it winds through forest and fields from Oak Creek area heading west past Mary's River to Wren.

Okay, I lowered the terrain rating to 2.5 - it's not THAT bad! It's a short hike, not a long haul.
