From the ferry dock in Friday Harbor; continue through town on Spring Street, in about a mile take a left on Douglas Road. Continue to a right-hand bend in the road; at this point the name changes to Bailer Hill Road. Follow this road to the coast where it turns north, parallels the shore and becomes the West Side Road. Go past Lime Kiln State Park; in another 2 miles come to San Juan County Park, turn into the entrance on your left. Smallpox Bay is directly in front of you, continue to parking.
