Trestle Loop Trail

Trestle Loop is a campground-circling hike of about 1.3 miles near Mill Creek. It follows parts of an old logging railbed through second-growth redwood, spruce, maple and alder forest. The creekside woods and railroad history are the main draw. Allow about 45 to 60 minutes for the circuit.

Start across from the campground campfire center, just northeast of the bridge. The path is not level throughout and has some steeper grades. The mapped line joins the open trail segments with a short campground-road link; follow the signed route on site where it differs from the map.

Hobbs, Wall & Company used this old railbed to haul logs to Crescent City. Look for traces of the logging route as you walk. Varied thrushes live in the forest, and their clear call can sound like a short train whistle. Berry picking is limited to one gallon per person per day.

Vehicle access to Mill Creek Campground depends on the seasonal gate. When it is closed, park along Highway 101 as directed by the park and walk in. Dogs are not allowed on the trail except for service animals. Current park information describes a 1.3-mile loop; other official listings and an older campground map round it to about 1.0 to 1.1 miles.
