Henline Falls Trail #3348 is a very easy out and back hike, perfect even for those folks who rarely hike. Because this trail is located in the Opal Creek Wilderness before starting on your hike you will have to fill out a free self issue wilderness permit if you hike here from Memorial Day to October 31st. The trail starts off very wide and level because this section used to be a forest service road, allowing kids to run up and down the trail and for adults to talk side by side. The trail takes you through a forest of red alder, Douglas fir trees, and western hemlock, with salal, Oregon grape, and sword fern littering the forest floor.
