Harrison Lake - Tunnel Creek Shelter - 7.8 Miles Round-Trip
The Tunnel Creek Trail to Harrison Lake is a 7.8 mile roundtrip hike to a small subalpine lake nestled at 4,700' within the Buckhorn Wilderness. The trail follows Tunnel Creek through a high canopied forest and features stunning views of the Buckhorn and Olympic mountain ranges.
Leaving from the Tunnel Creek Trailhead (0.0 miles : 2,700') the trail rises gently through a narrow riparian corridor rife with seasonal logjams and downfall. The trail slowly veers up and away from the creek riding a hillside above the valley floor (.5 miles : 2,650'). Tunnel creek disappears from eyesight, but it will rarely escape earshot.
The trail briefly levels out as it leads through a mature hemlock grove (1.0 miles: 2,950'). The towering old growth hemlocks provide a distinct dichotomy to the young saplings which fill the forest floor.
The trail continues beneath the high forest canopy, parallelling Tunnel Creek (1.5 miles : 3,215'). Occasional breaks in the trees offer views of the Tunnel Creek Valley and the base of Mt Constance.
Continuing on its gentle ascent, the trail reaches the Tunnel Creek Shelter - one of the few established backcountry camping options (2.75 miles : 3,700').
The trail passes the shelter (3.0 miles : 3,805'), crosses Tunnel Creek and begins a very aggressive ascent to Harrison Lake (3.9 miles : 4,700'). The trail will climb 900' in the final .9 miles with grades that can exceed 30 degrees.
The trail continues .5 miles past Harrison Lake to the Dosewallips Divide (4.4 miles : 5,050' - where views are impressive.
