The Mainline Loop is a popular route through the Boxley Creek region. This route utilizes the two most popular trails in the area (Mainline and Ethan's) to make a climb-then-descend loop. The climb is all done on Mainline and ends at the top by the horse farm (you'll know it when you see it). The descent is all done on Ethan's Enduro Course, which offers a great flow with a few features and options. After exiting Ethan's onto the Snoqualmie Valley Trail, head downhill/Northeast to get back to the Mainline entrance.
