The entire Lost Lake Trail 1185 trail is within the Norse Peak Wilderness.

Experience clear blue alpine lakes and wildflowers on this trail and hike through old growth forest. You may spot several signs of wildlife: from deer and elk tracks to fresh tree scars from black bears. Lost Lake this is a wonderful late summer and early fall hike or ride.

Traveling north to south:

Begin at the junction with the Greenwater Trail 1176 and climb through old growth timber towards Quinn and Lost Lakes. Along the way keep an eye out for calypso orchids, wild ginger Sitka valerian, columbine, fringecups, yellow violets and trillium growing on the lower portions of the trail before you arrive at the Greenwater Lakes. Two miles into your hike Quinn Lake comes into view, a crystal clear alpine lake in the mist of the wilderness. Just a little further, at mile 2.6, arrive at Lost Lake with good campsites and horse feed available.

Continue past Lost Lake through sub-alpine timber and open country with scenic views of alpine lakes, the valley and the Cascade Mountain Range as you head to Noble Knob. Climb the trail to the north to the Noble Knob Trail 1184 junction at mile 5.1.
