Tunnel Creek Trail Hike
Craig Romano | author
Olympic National Forest’s Tunnel Creek Trail lies just a few miles south of the popular Big Quilcene Trail. But unlike the Big Quil which leads to Marmot Pass, a high windswept wildflower-rich gap providing sweeping views—the Tunnel Creek trail travels mainly beneath a thick canopy of primeval forest. Lacking the wow factor of Marmot Pass, Tunnel Creek gets passed over by many a hiker. However, those who take to this trail less taken soon discover; Tunnel Creek offers plenty of delightful spots and some pretty decent views as well. And all without the crowds of Marmot Pass.
Hit the Trail
The Tunnel Creek Trail immediately enters the 44,258-acre Buckhorn Wilderness, the largest roadless area in Olympic National Forest. Much of the wilderness lies within the Olympic rain shadow encompassing some of the driest mountainous terrain in the Olympics. But here at the wilderness’s southern reaches, precipitation increases. And it’s noticeable immediately upon starting up the trail. The surroundings are verdant—draped in mosses and lichens. The trees are grand. And the valley is alive with the sound of cascading water.
Work your way up a tight valley following alongside tumbling South Fork Tunnel Creek through a tunnel of towering old-growth western hemlocks and Douglas-fir. The hike is magical, almost ethereal on a misty morning. And it’s welcoming on a sweltering summer day, as the ancient trees do an excellent job of regulating the temperature, providing some much appreciated air-conditioning.
After 3.3 miles and gaining a modest 1500 feet of elevation, reach the still intact Tunnel Creek Shelter. A remnant from when this trail was much longer (before logging and roads obliterated much of it). In the early days of Olympic National Forest and Olympic National Park there were more than 90 trailside shelters in the Olympics. Many were developed through the guidance of Frederick William Cleator, who became one of the nascent US Forest Service’s first recreational specialists. Along with calling for trails, shelters, and fire lookouts, Cleator also advocated for a large portion of the Olympics to be left as wilderness, free from any developments.
The early shelters were meant to help administer the forest by providing rangers, trail workers and foresters a place to overnight while traversing the vast wild lands of the Olympics. But they were also welcomed by the few backpackers who plodded into the Olympic backcountry at the time. Through the years many of the shelters succumbed to fire, collapse and disrepair. And as recreational use increased and attitudes changed regarding land management, many hikers and land managers began to question the role of these structures in the wilderness. Under new directives many of the shelters were allowed to fall in disuse or were intentionally dismantled.
Many recreationists however continued to argue for the need of these shelters to provide emergency cover for backcountry users caught in severe weather. Many other recreationists including this author have argued to maintain the remaining shelters now numbering only around 20 as historically significant and preserve them as historic structures.
The Tunnel Creek Shelter is one of the last remaining in Olympic National Forest. Perhaps use it for a lunch break. Reflect on its long history and the role it has played providing refuge to many a wanderer on a cold and wet day. And help protect it from misuse. Beyond the shelter, the trail crosses via a log bridge the South Fork of Tunnel Creek and then gets down to business. They way now steadily and steeply climbs out of the valley ascending a thickly forested ridge. Eventually reach a small saddle in the ridge harboring two small bodies of water. The first is a small grassy pond known as Karnes Lake. Just beyond and a little higher up at 4.3 miles from the trailhead and at an elevation of 4300 feet is the more appealing Harrison Lake.
You don’t want to call it quits yet however. Conjure up a little more energy and continue hiking, ascending through open forest and over ledge coming to the 5050-foot ridge crest at 4.7 miles. Now take in an exceptional view of 7,743-foot (third highest peak in the Olympics) Mount Constance’s impressive sheer vertical east face.
You can scramble along the rocky ridge a little higher to better appreciate Constance’s towering presence, less than two miles away to the northwest.
For most hikers this is the turning around spot. But the trail continues from here making an insanely steep drop of more than 4300 feet in 3.6 miles to the Dosewallips River Road. It’s brushy in spots and easy to lose along the ridge. Otherwise it’s in decent shape down steep slopes and through old growth and past a small waterfall at Gamm Creek.
f you can arrange a car shuttle consider hiking out this route. There are some good views down to the Dosewallips River valley and out to Hood Canal during the initial descent if you want to just wander a little way down the trail. Otherwise start heading back to the cool forests of South Fork Tunnel Creek on the much more agreeable trail back to your start.
