The trailhead is just north of the old mill pond from Waite Mill, one of the largest employers near Granite Falls in the early 20th century. Most of the trail follows the route of the original Everett and Monter Cristo railbed along the south shore of the Stillaguamish, passing an old Lime Kiln, after which the trail is named. The rails were removed in the mid-1930s, after which it was possible for a while to drive automobiles on the old railbed and trestles. The trail ends where the railroad crossed the river and immediately entered Tunnel #1. Remains of the old Howe Truss Bridge can be seen below in the river if you look carefully.
