Through no small feat, but rather small volume, Devil Creek has created itself quite an impressive canyon over the years. The final 3/4 of a mile of the creek is spend meandering through a twisting 100 foot deep slot gorge. If that weren't enough for the geology nuts out there, add Boulder Cave and this pretty waterfall to the picture. The falls begin by sliding 10 feet over a rugged pitch of basalt (I had previously listed this 10-foot fall as Middle Devil Creek Falls, but it should be considered part of the main fall itself) into a flume-like portion of the canyon, then bends left and encounters a slot in the ground no more than a foot wide where the creek sprays into a large, dark, undercut amphitheater recess. It's almost like an underground waterfall, quite surreal. The creek then enters 500 foot long Boulder Cave, formed where the water undercut the canyon so deeply that it collapsed on itself. The creek now flows through the cave, and proceeds downstream, flowing placidly through the narrow canyon until it enters the Naches River. If you plan on walking through the cave (why wouldn't you), don't forget to bring a light or lantern. There is a $5.00 fee for day use at Boulder Cave (the various recreation passes do not not cover this location).
- Lower Devil Creek Falls is the Colloquial name of this waterfall.
Located near Cliffdell, off Highway 410, east of Mount Rainier National Park. On Highway 410, proceed just under 27 miles east of Chinook Pass, or 4.7 miles west of the Naches Ranger Station, to Old River Road (FR 1704), signed for Boulder Cave. Follow Old River Road to its end at the Boulder Cave Recreation Area. Follow the marked trail towards Boulder Cave, reaching the upper entrance in 1/2 mile. Before entering the cave, depart the trail, and walk up the rocky streambed for 500 feet to the bottom of the falls. After passing through the cave, and as long as the creek isn't running high, I recommend walking back to the parking lot through the canyon. It doesn't involve any technical climbing of any sort, but you will have to wade through knee deep water at one point, so bring your sandals. If you don't wish to walk down the canyon, the trail through the cave and back to the car is 1 1/2 miles round trip.
