Cathedral Falls is a 248 foot waterfall along an unnamed tributary of Goat Creek in an isolated corner of Mount St. Helens National Volcanic Monument. Cathedral Falls gets its name from the massive overhang the falls plunge from. The Goat Creek trail traverses behind the falls via the undercut, which has a massive church cathedral ceiling. The name Leona Falls has also been applied at times, after a Ranger in the Gifford Pinchot National Forest. At the peak of runoff season the falls can be quit spectacular with a considerable volume of water pouring over the cliff,.
Cathedral Falls is accessed from the Goat Creek Trail south of Riffe Lake. Drive east from Morton along Highway 12 and turn right onto Kosmos Road, (There will be a sign for Riffe Lake and Taidnapam Park). Then turn left, still following signs for Riffe Lake and then proceed another 4 1/4 miles across the bridge over the Cowlitz river. Turn right immediately on the other side of the bridge, follow the gravel logging road for 3/4 mile, and then bear left again onto FR 2750 (which isn’t signed). Shortly after turning onto Road 2750 is a sign pointing the way to the Goat Creek Trail, which is reached in another 3 3/4 miles of narrow and winding, but generally good condition road. The trail is unsigned but is obvious where it follows the old roadbed. Cathedral Falls is encountered after an easy mile of hiking.
