From I-5, take exit 240 (Alger) and head west on Lake Samish Road. Take the first left onto Barrel Springs Road and travel 0.6 mile, to where there is a sign reading “Blanchard Forest Block”.
Turn right on the dirt road and travel another 1.7 miles to the junction marked “Samish Outlook”. Without turning, stay straight and follow signs to the UPPER TRAILHEAD. At the end of the road is a large parking lot.
