If you exit the trail in Woodinville, take 175th east, follow it up the hill (it becomes Woodinville-Duvall Rd.), right at the T and continue on the Woodinville-Duvall Rd. all the way to Duvall. Woodinville-Duvall is a busy road, but it has decent shoulders. The section just before E. Snoqualmie Valley Rd. is narrow with no shoulder and limited sight lines, but the rest is OK.
