Wander through carpets of dazzling wildflowers along the shoreline of the monument’s second largest lake. Formed when debris and earth from the 1980 eruption dammed Coldwater Creek, Coldwater Lake is now over four miles long and 200 feet deep.  Wildlife is prolific and views are nonstop on this rolling lakeshore trail.


Enjoy spectacular wildflower displays along Coldwater Lake.

Follow the Lakes Trail along massive Coldwater Lake. Hike through former clear-cuts and across the blast zone. Once a devastated landscape, now enjoy flowered slopes and shady emerald groves of alders, willows, and cottonwoods. The way gains no net elevation but plenty of cumulative elevation is racked up along the way rolling up and down bluffs and ledges.

Throughout the hike enjoy good viewing of surrounding Coldwater Peak and the stark southern face of Minnie Peak. Pass the Elk Bench Trail which climbs left to the former Coldwater Science and Learning Center. Continue right reaching a wonderful lakeside spot at water’s edge at 1.1 miles. This is perfect spot to call it a hike if out with young children.

Otherwise keep hiking passing some fallen giant firs, reminder of the grand forest that once grew here. Cross the first of many creeks too, eventually coming to one donning a pretty waterfall. Next skirt some cliffs before climbing across some steep ledges high above the lake. Use caution here as the drop off is steep.

Descend and cross another series of creeks reaching a wide rocky outwash. Follow cairns across the open rocky and sandy terrain eventually coming to a daisy dotted flat at lake level. The trail continues, reaching the lake’s marshy eastern end. Look for beaver activity here among the alder thickets. Now following Coldwater Creek the way begins to climb reaching a junction with the Coldwater Trail at 4.5 miles. This is a good spot to turn around—but before doing so just walk a short distance south on the Coldwater Trail to a sturdy bridge spanning the thundering creek. Admire it cascading through a tight chasm—then cast your eyes upward to stone gargoyles peering down upon you from stark faced Minnie Peak.
