Eightmile Creek Falls near Centerville, Washington is a moderate 0.2-mile out-and-back hike to the waterfall, Eightmile Creek Falls.
Eightmile Creek Falls can be reached from above via the official, wide, road-converted-trail, but for a quick access and a much better view of the falls from down below, find an obscure user path leading out from behind the picnic shelter, and follow it. Aim to the left, towards a steep slope and cliff. If you go to far to the right, and end up at a dead end at the creek, do not follow the creek into it's deep slot canyon. Aim to the left. The path ascends the cliff through a narrow, steep, chute. It is short and quick to ascend.
Follow the path once at the top, and make your way up the ridge, following the sound of the falls. The best view of the falls is up the ridge, on a boulder field. There are also great views of the narrow basalt gorges carved out by the creek.
The user path may be more visible in winter, during my visit. During summer, the path may be more overgrown. Watch out for poison oak and rattlesnakes!!!
