From a historic ranger station, travel back into the early days of the Olympic National Forest. Then amble under moss-draped trees to an isolated gurgling fishing hole on the Duckabush River.

This short trail leads to, not along, the Duckabush-stoking your anticipation as it cuts its way through a dense and dank forest delivering you to a sunny ledge above the tumbling and churning river. But before you make a beeline to the river, a little historical appreciation is in order. Start by admiring the Interrorem Cabin. Built in 1907, this structure is the oldest Forest Service dwelling on the Olympic Peninsula. Interrorem served as a ranger station, a base for Works Progress Administration and Civilian Conservation Corps workers, and a fire guard station. Currently it's rented out by the Forest Service for the public to use overnight. Be sure to respect the privacy of any guests who may be staying in the cabin while you're visiting.

The first overnighter at Interrorem was Ranger Emery Finch. Mr. Finch, an avid fisherman, was responsible for building the Ranger Hole Trail-a path to his favorite fishing spot, the ranger's fishing hole. The trail leads 0.8 mile to that revered spot. Through mature second growth (cut circa Finch's tenure) the good path climbs a little hump then makes a slow descent toward the river. In April hundreds of trilliums line the way. As the Duckabush's roar becomes more audible, the trail makes a steep drop, emerging at the famed fishing spot.

While the fishing isn't what it used to be, you'll still catch some good views of the river. The Duckabush crashes through a narrow chasm here. Frothy gurgling waters crash up against the narrow cleft. Be sure to keep small children nearby while admiring this landmark. On your return, take the 0.3-mile interpretive loop for more information on the Interrorem Cabin and the Ranger Hole.
