Snow Lake Trail #1013 begins mildly, cutting a long swath through fields of bracken fern and salmonberry before entering a forest of hemlock and fir. At 1.7 miles, the trail meets up with Source Lake Trail #1013 (signed Source Lake Overlook Trail) which was the primary route to Snow Lake before washouts prompted building a more direct route over the cliffs. Stay to the right on the Snow Lake Trail, following the newer route to the lake.

Switchback steeply up the rocky ridge, crossing into the Alpine Lakes Wilderness and reaching the ridgetop at a saddle at 2.5 miles. At the saddle is another junction with the Source Lake Trail #1013.2 to the left; stay right on the Snow Lake Trail to descend to the shores of Snow Lake.
