Directions to Trailhead

Smith Lake is an often-forgotten lake that is nestled in the forest at Castle Junction. It is a stunning green-blue colour and a great place for fishing. Nearby Copper Lake is only a 0.6 km side trail that is a must-see on this route. If you are looking for a quick walk in the woods, this is a wonderful option.
