Access is on river right just downstream of the outlet from Elk Lake. From Forest Road 2480 that runs along river right on the Hamma Hamma, it's a 2.2 mile drive up Forest Road 2401 to the turn off for the Elk Lake Trailhead. It's a short drive down of a couple hundred yards down the Forest Road 2480-012 spur to the trailhead. Hike in a short distance to Jefferson Creek.
