The Whetstone Vista Trail #602 begins on County Road 738, Brush Creek Road, and ends at an intersection with the Upper Upper Loop Trail #435.1A. This trail ascends through a dense aspen grove that has excellent colors in the fall. During the summer, this is where the best wildflowers can be seen, especially at the Upper Upper Loop Trail end. This trail offers great view of Whetstone Mountain across the valley and southern valley views. Geo-Ref Trail Map Geo-Reference Instructions
