The Crown Zellerbach Trail, known locally as the CZ Trail, follows a former logging railroad through quiet and picturesque forests in northwest Oregon. Its east end begins at Multnomah Channel and, from there, the trail continues for 25 miles on a northwest course largely paralleling the Scappoose-Vernonia Road from Scappoose to Vernonia. (Note that the last 4.2 miles of the route are on-road.)
In Vernonia, the CZ Trail ends only about a quarter mile from the paved Banks-Vernonia State Trail, which offers another 22 miles of scenic riding through wooded and rural landscapes.
To begin at the Scappoose Trailhead: From Highway 30 northbound, turn left (west) onto Scappoose-Vernonia Road and follow the signs toward Vernonia. Continue on Scappoose-Vernonia Road for about 2 miles until you reach the trailhead and parking area at Sam Blehm Road. (Note that this trailhead is about 4 miles from the official east end of the trail at Chapman Landing.)
Unimproved along sections, and some muddy spots. But gorgeous. Everything the Banks Vernonia LT used to be before it was paved and became a bicycle race track.
Ran half of it (from Vernonia) with a friend today (2/27), and it was very muddy. We had fairly appropriate tires, but full mountain bike knobbies would have certainly helped. The trail would be much more enjoyable after about three rain-free weeks. The first stretch out of Vernonia is pretty steep, but once you cross the paved road it levels out a lot. One other thing to note is that if you ride the paved road on the return leg, the chance of an encounter with an angry motorist is pretty likely. We had several.

The CZ Trail does not go through at tunnel, but the old logging rail road did.

Near the West end the map shows the trail as veering North on the Columbia Forest Road. You can go this way, but the CZ Trail actually crosses the Scappoose-Vernonia Hwy about 16.7 miles from Scappoose. Google Maps shows it continuing on Pebble Creek Mnln (whatever Mnln means). Strava identifies the road as Crown Zellerbach Trail. Signage identifies Pebble Creek Mnln as the CZ Trail. Pebble Creek Mnln turns in to E Knott Street in Vernonia.
The trail is very lovely. Smooth packed gravel for the most part. Wet and a bit muddy in places when I road it on New Years Eve. If riding in winter use wide tires. I had 2.25" and was glad for it.
