Share Album Published August 29, 2019 Spruce Lake (1 new item) Trailhead: Fern Lake Via: Fern Lake Distance: 4.8 mi Elevation Change: 1,510' The spur trail to Spruce Lake is actually a hundred yards or so short of Fern Lake. This is a very pretty trail but can be difficult to follow at times, particularly a cairn marked section through a boulder field. The trail also passes through a few marshy spots with boardwalks.
