Fort Stevens has seven miles of bike trails and, combined with the lightly traveled roads, you can create over 35 miles of riding from Astoria.
Start with a morning coffee underneath the Megler bridge, then head west out US route 101. You cross the Young’s Bay bridge which isn’t particularly attractive. Alternatively, you can cross south of town over the Old Young’s Bay bridge, but it adds a few miles.
Once you cross the bridge, turn right onto Harbor way towards downtown Warrenton. Harbor continues through town and just as you cross First street, you’ll see the trailhead of a bike path on the right. This is part of a bigger planned loop throughout the region. Be sure to ride the segment that begins at Carruthers park and follows along the Columbia river.
Once that segment ends, turn right on Pacific drive and follow it all the way into Fort Steven’s state park. You can stop at the visitor’s center to review the history and grab a trail map of the park. From here I recommend following the bike trail out to Jetty road. You can continue riding on the lightly traveled Jetty road to one or both view points.
After climbing the Jetty observation tower, I elected to carry my bike down to the beach to ride along the hard packed sand to , where I picked up the pike path again heading south to the wreck of the Peter Iredale. If you want to stick to paved surfaces, you can head back the way you came on Jetty road and join the Peter Iredale path at.
Once you’ve taken your pictures and inspected the wreck, head on the trail to Coffenbury lake, a beautiful mountain lake on the coast. If it’s hot, jump in for a swim. There are also restrooms nearby. Continue through the campground and out of the park to NW Ridge road. Take a right and follow Ridge to 9th, where you’ll take a left back into Warrenton.
Ride through town on Main and take a right on Harbor to return to Astoria.
