Boulder River Waterfall Trail Professional Review and Guide
"A gentle trail, smooth and level enough for small children, takes families comfortably through old-growth forest beside a glacier-fed river in the Boulder River Wilderness. A magnificent destination is the spectacular wall-curtain waterfall at 1.25 miles. A bit beyond, an open area by the river makes a pleasant camp or lunch stop. One particular reason for preserving this valley as wilderness is that it contains one of the few remaining low-elevation old-growth forests.
Foresters estimate the age of some of the trees at 750 years. All along the path are awesome old-growth Sitka spruce, silver fir, western red cedar, western hemlock, and Douglas fir. The accompanying mosses, ferns, berries, shrubs, and flowers are samples of what, before logging, all the low-elevation North Cascades valleys were like."
