Mill Creek Trail Professional Review and Guide
"From its origin on the remnant slopes of ancient Mt. Tehama, Mill Creek tumbles through the southwest corner of Lassen Volcanic and across Forest Service land toward the Sacramento Valley. River runners and anglers regard sections of this creek as special places to ply their crafts. This section of the fabled stream has a 14-mile stretch of little-used trail that heads downstream through varied zones of vegetation that include montane forest, chaparral, and oak woodland.
Despite what Mill Creek Trail’s name implies, the creek stays out of sight for most of the journey, which is generally high above the water across the steep slopes of the canyon; indeed, the first unobstructed, bona fide view of the creek doesn’t come for 7.5 miles. However, dayhikers will find a walk along the first 6 miles to be a pleasant, forested stroll, and backpackers will find some little-used campsites near 4.25 and 6 miles."
