Cougar Creek is the first major tributary upstream from the mouth of Salmon Creek. Excellent riparian woodlands remain along much of the deep ravine in the lower reaches. Exposed sandstone along the stream bank bears the names and initials of visitors from over the past fifty years. The trail here connects NW 119 Street with the Salmon Creek Trail. This trail is a 6 to 12-foot-wide crushed gravel path that is relatively flat and parallels the Cougar Creek. The entry from 119th Street is a steep slope down to the trail from the sidewallk. The trailhead from the Salmon Creek is a steep uphill path to the main trail. There is a picnic table under some Douglas Fir trees, steps and a steep slope at the intersection with the Salmon Creek trail (at about the half way point on the trail).
