Park at the Tafton Trailhead, 4 miles east of Arlington, by an old barn or at one of the other trailheads further east for a shorter ride and ride east towards Darrington. At mile 7, pass the site of the 2014 Oso Landslide, a sobering site which now hosts a memorial for the victims of the slide. Continue east ~21 miles to Barco and turn right on 512 Drive NE and then immediately right again to reach Squire Creek Campground. This road crosses private property. Be respectful and watch for farm animals. If desired, continue to Darrington from the Squire Creek Campground by riding 3.5 miles on SR-530.

  • The trail is overall in good condition, but not regularly maintained so downed trees and bushes close to the trail can be encountered especially closer to Darrington.
  • As of Nov 2022, there are currently two closures. The first is between the Centennial Trail connection and the Trafton Trailhead. The second is just west of 435th Ave NE near Darrington. These closures are because of landslides and river washouts. The remainder of the trail is open to the public and much of the trail has recently been resurfaced with compacted gravel.
