Hiking Cedar Flats Nature Trail

The Cedar Flats Nature Trail is an 112-acre old growth mixed forest of western red cedar, Douglas fir, and western hemlock in the Cedar Falls Natural Recreational Area that was officially preserved in 1946. It's a peaceful stroll through deep, quiet forest, perfect for children and grown ups alike. The old growth grove begins immediately upon entering the forest from the road with a tall canopy and fern dominated understory.

The trail is an easy one mile walk along the forest floor, so it'll be friendly to little hikers. There are interpretive signs and several benches along its route. Just after a quarter mile, a bridge takes hikers over a small depression that leads to the Muddy River. After another eighth of a mile, the trail splits into a loop. At this point the trail narrows and meanders through the forest. Going left will bring hikers along a small bluff that overlooks the Muddy River, offering a partial view of the Gifford Pinchot National Forest. Just before the trail rejoins itself at the original split, there is a tree over the trail that requires walking around.

A few downed trees spanning the trail and sawed have growth rings showing them to be more than 500 years old. Part of the trail borders a small bluff on the west side of the Muddy River, offering a partial view of the Gifford Pinchot National Forest.

WTA Pro Tip: Save a copy of our directions before you leave! App-based driving directions aren't always accurate and data connections may be unreliable as you drive to the trailhead.

Getting There

Drive east on State Route 503 (the Lewis River Road) for 48 miles to the small community of Cougar. Continue through town, entering the Gifford Pinchot National Forest and in 18 miles, arrive at a junction with Forest Road 25.

Your road (now Forest Road 90) makes a right turn at this junction, but you continue straight ahead on FR 25. Drive another 3.6 miles to paved shoulder where you can park along FR 25 for the Cedar Flats Natural Area. The sign marking the entrance is difficult to see until parked.

Note that FR 25 is closed in winters, typically until late May but sometimes later.
