When we had an office in the city of Granite Falls, often tourists would stop in to ask "Is there really a falls?"
Yes - there is a falls - it is located about a mile east of town on the road to the popular camping areas of the Mt Baker National Forest located further up Mt. Loop Highway.
Just before the first bridge where the highway crosses the Stilliguamish River, if you look closely, you can see the sign at the trail head. A small parking lot has trail access on both ends.
